Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information .
171-404: Geography (from Ancient Greek γεωγραφία geōgraphía ; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth . Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities —not merely where objects are, but also how they have changed and come to be. While geography
342-543: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in
513-472: A "bitter river" ( Oceanus ), with seven islands arranged around it so as to form a seven-pointed star. The accompanying text mentions seven outer regions beyond the encircling ocean. The descriptions of five of them have survived. In contrast to the Imago Mundi , an earlier Babylonian world map dating back to the 9th century BC depicted Babylon as being further north from the center of the world, though it
684-466: A consequence of accessibility ." Geography is a branch of inquiry that focuses on spatial information on Earth. It is an extremely broad topic and can be broken down multiple ways. There have been several approaches to doing this spanning at least several centuries, including "four traditions of geography" and into distinct branches. The Four traditions of geography are often used to divide the different historical approach theories geographers have taken to
855-494: A consequence of cartography shifting from simply producing maps to producing spatial information, influenced by a culmination of information theory and technology like the World Wide Web . Attempts at subdividing geography have often been met with criticism. Geography has a history spanning cultures and thousands of years and is described as a "mother science" from which more specialized disciplines emerge, resulting in
1026-740: A core focus of technical geography. In statistics, frequency refers to the number of occurrences of a particular event or value within a dataset. When dealing with spatial and temporal datasets, the concept of frequency can be applied to understand how often certain events or values occur across different locations (spatial) or over time (temporal). Spatial datasets contain data points that are associated with specific geographic locations, and frequency in spatial datasets can be used to analyze patterns and distributions across different areas. Temporal datasets involve data points that are associated with specific time points, and frequency in temporal datasets helps analyze trends and patterns over time. Analyzing how
1197-460: A deep understanding of the map's use case, the audience's needs, and the geographical context. Technological advancements, such as the World Wide Web (WWW), Geographic information systems (GIS), and information theory have greatly aided cartographers in generalizing maps more efficiently and consistently. These tools can apply generalization rules systematically, ensuring high-quality outputs even as data volume increases. Cartographic generalization
1368-417: A different model. More controversially, others deny the idea that the thought and techniques of geography constitute a new branch. This argument asserts that geography must be applied and, therefore, must focus on some subset of human or physical geography. They also argue that there is not enough well-established peer-reviewed literature to back the term as a new branch. Some have brought allegations that
1539-474: A distinct category vary. When subdividing the discipline within the literature, similar categories—such as "the Spatial Tradition", "techniques of geographic analysis", "geographic information and analysis", "geographic information technology", "geography methods and techniques", "geographic information technology", "scientific geography," and " quantitative geography " —are used to describe
1710-525: A fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in the Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as
1881-417: A fragmented discipline. Other existing models to subdivide the discipline of geography into categories and focuses, including William Pattison's four traditions of geography , vary dramatically between publications and cultures. While the term technical geography has been put forward as a distinct branch and umbrella for these wider concepts, the terms used to describe the study of spatial information as

#17327659243502052-416: A geographic information system). Remote sensing aids in land use, land cover (LULC) mapping, by helping to determine both what is naturally occurring on a piece of land and what human activities are taking place on it. Geostatistics deal with quantitative data analysis, specifically the application of a statistical methodology to the exploration of geographic phenomena. Geostatistics is used extensively in
2223-441: A geography. For something to exist in the realm of geography, it must be able to be described spatially. Thus, space is the most fundamental concept at the foundation of geography. The concept is so basic, that geographers often have difficulty defining exactly what it is. Absolute space is the exact site, or spatial coordinates, of objects, persons, places, or phenomena under investigation. We exist in space. Absolute space leads to
2394-608: A high level of information for Ptolemy to construct detailed atlases . He extended the work of Hipparchus , using a grid system on his maps and adopting a length of 56.5 miles for a degree. From the 3rd century onwards, Chinese methods of geographical study and writing of geographical literature became much more comprehensive than what was found in Europe at the time (until the 13th century). Chinese geographers such as Liu An , Pei Xiu , Jia Dan , Shen Kuo , Fan Chengda , Zhou Daguan , and Xu Xiake wrote important treatises, yet by
2565-509: A particular subject or activity and involving practical skills, and " geography ", from the Greek γεωγραφία (geographia, a combination of Greek words ‘Geo,’ The Earth, and ‘Graphien,’ to describe. Literally "earth description"), a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. Technical geography as a distinct term in the English language within
2736-498: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment
2907-561: A product with greater information than a two-dimensional image of places, names, and topography. This approach offers more inclusive strategies than more traditional cartographic approaches for connecting the complex layers that makeup places. Ethnographical research techniques are used by human geographers. In cultural geography , there is a tradition of employing qualitative research techniques, also used in anthropology and sociology. Participant observation and in-depth interviews provide human geographers with qualitative data. Geopoetics
3078-686: A remote corner of the country knows its value." Remote sensing technology again advanced rapidly during World War II , and the techniques employed were rapidly assimilated as aids in geographical studies. During the Cold War , advancements in photography, aircraft, and rockets only increased the effectiveness of remote sensing techniques. As the technology became available to the general public, geographers were soon overwhelmed with large volumes of satellite and aerial images. New techniques were required to store, process, analyze, and use this new data source, birthing remote sensing scientists. Coinciding with
3249-409: A signal with a delayed copy of itself over successive time intervals. Autocorrelation is the foundation of Tobler's first law of geography . Spatial autocorrelation is measured with tools such as Moran's I or Getis–Ord statistics . Autocorrelation is fundamental to technical geography because it provides critical insights into the spatial and temporal structure of geographical data. It enhances
3420-478: A single person from a single location. The European Age of Discovery during the 16th and the 17th centuries, where many new lands were discovered and accounts by European explorers such as Christopher Columbus , Marco Polo , and James Cook revived a desire for both accurate geographic detail and more solid theoretical foundations in Europe. In 1650, the first edition of the Geographia Generalis
3591-542: A strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to a lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either

#17327659243503762-432: A structured or semi-structured approach during interviews involving specific questions or discussion points when utilized for research purposes. These questions are designed to extract focused information about the research topic while being flexible enough to allow participants to express their experiences and viewpoints, such as through open-ended questions. The concept of geography is present in all cultures, and therefore
3933-484: A subdiscipline within technical geography, focusing exclusively on new quantitative methods, such as spatial statistics, time geography (including visualizations such as the space-time prism and continuous transportation modeling approach), and GIS, for handling spatial-temporal data generated by novel technology like GPS and remote sensing. This part of technical geography focuses on spatial statistics and visualizing spatial information, emphasizing quantitative data and
4104-432: A system. The amount of time an individual, or group of people, spends in a place will often shape their attachment and perspective to that place. Time constrains the possible paths that can be taken through space, given a starting point, possible routes, and rate of travel. Visualizing time over space is challenging in terms of cartography, and includes Space-Prism, advanced 3D geovisualizations, and animated maps . Scale in
4275-463: A three-branch model of technical, human, and physical geography, referring to human and physical as the primary two. The benefit of this wording is that it is consistent with the other two branches and clearly places the discipline within geography. The categorization of technical geography in the EOLSS as a branch is expanded upon by Ionel Haidu in his 2016 paper What is technical geography as being
4446-417: A variety of fields, including hydrology , geology, petroleum exploration, weather analysis, urban planning , logistics, and epidemiology . The mathematical basis for geostatistics derives from cluster analysis , linear discriminant analysis and non-parametric statistical tests , and a variety of other subjects. Applications of geostatistics rely heavily on geographic information systems , particularly for
4617-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and
4788-603: Is about geographic information." GIScience is mentioned explicitly as being separate from quantitative geography, but under the branch of technical geography. In 1995, the University Consortium for Geographic Information Science (UCGIS) was established in the United States to support the field of GIScience, such as the creation of a "model curricula" by geographer Duane Marble to help educators teach GIScience. There has been significant debate around
4959-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected
5130-739: Is an interdisciplinary approach that combines geography and poetry to explore the interconnectedness between humans, space, place, and the environment. Geopoetics is employed as a mixed methods tool to explain the implications of geographic research. It is often employed to address and communicate the implications of complex topics, such as the anthropocene . Geographers employ interviews to gather data and acquire valuable understandings from individuals or groups regarding their encounters, outlooks, and opinions concerning spatial phenomena. Interviews can be carried out through various mediums, including face-to-face interactions, phone conversations, online platforms, or written exchanges. Geographers typically adopt
5301-436: Is an ongoing source of debate in geography and is unlikely to be resolved anytime soon. Several laws have been proposed, and Tobler's first law of geography is the most generally accepted in geography. Some have argued that geographic laws do not need to be numbered. The existence of a first invites a second, and many have proposed themselves as that. It has also been proposed that Tobler's first law of geography should be moved to

5472-412: Is concerned with the study of processes and patterns in the natural environment like the atmosphere , hydrosphere , biosphere , and geosphere . Technical geography is interested in studying and applying techniques and methods to store, process, analyze, visualize, and use spatial data. It is the newest of the branches, the most controversial, and often other terms are used in the literature to describe
5643-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in
5814-478: Is credited to Hipparchus . He employed a sexagesimal system that was derived from Babylonian mathematics . The meridians were subdivided into 360°, with each degree further subdivided into 60 ( minutes ). To measure the longitude at different locations on Earth, he suggested using eclipses to determine the relative difference in time. The extensive mapping by the Romans as they explored new lands would later provide
5985-494: Is foundational in technical geography because it ensures that maps are functional, readable, and tailored to their intended use. It balances the need for detail with the practical limitations of scale and medium, enhancing the effectiveness of maps as tools for communication, analysis, and decision-making. The term "technical geography" is a combination of the words " technical ", from the Greek τεχνικός (tekhnikós, translated as artistic, skillful, workmanlike), meaning relating to
6156-463: Is impacted by all other locations on Earth. In one of Yi-Fu Tuan 's papers, he explains that in his view, geography is the study of Earth as a home for humanity, and thus place and the complex meaning behind the term is central to the discipline of geography. Time is usually thought to be within the domain of history , however, it is of significant concern in the discipline of geography. In physics, space and time are not separated, and are combined into
6327-442: Is impractical and can overwhelm the map reader. The primary goal of cartographic generalization is to balance detail with readability, ensuring that the map serves its intended purpose without sacrificing essential information. By placing data in a spatial context, even though it is generalized, cartographic generalization creates additional information by revealing patterns and trends in the data. Effective generalization requires
6498-414: Is not certain what that center was supposed to represent. The ideas of Anaximander (c. 610–545 BC): considered by later Greek writers to be the true founder of geography, come to us through fragments quoted by his successors. Anaximander is credited with the invention of the gnomon , the simple, yet efficient Greek instrument that allowed the early measurement of latitude . Thales is also credited with
6669-489: Is not their main preoccupation. Geographers study the Earth's spatial and temporal distribution of phenomena, processes, and features as well as the interaction of humans and their environment . Because space and place affect a variety of topics, such as economics, health, climate , plants, and animals, geography is highly interdisciplinary. The interdisciplinary nature of the geographical approach depends on an attentiveness to
6840-531: Is one of the broadest, is consistent with the naming convention of the other two branches, has been in use since the 1700s, and has been used by the UNESCO Encyclopedia of Life Support Systems to divide geography into themes. As academic fields increasingly specialize in their nature, technical geography has emerged as a branch of geography specializing in geographic methods and thought. The emergence of technical geography has brought new relevance to
7011-489: Is only possible through cartographic generalization. More than just reducing the overall level of information, cartographic generalization helps discover patterns and trends in data that underlie many techniques and technologies employed and investigated by technical geographers. Autocorrelation is a statistical measure used to assess the degree to which a given data set is correlated with itself over different time intervals or spatial distances. In essence, it quantifies

7182-452: Is related to everything else, but near things are more related than distant things." As spatial interrelationships are key to this synoptic science, maps are a key tool. Classical cartography has been joined by a more modern approach to geographical analysis, computer-based geographic information systems (GIS). In their study, geographers use four interrelated approaches: Quantitative methods in geography became particularly influential in

Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" ( c. 276 BC – c. 195/194 BC ). The first recorded use of

However, he still believed that the Earth was a flat disk, as did many of his contemporaries. One of the first estimates of the radius of the Earth was made by Eratosthenes . The first rigorous system of latitude and longitude lines
7695-534: Is the study of earth's seasons, climate , atmosphere , soil , streams, landforms, and oceans. Physical geographers will often work in identifying and monitoring the use of natural resources. Human geography (or anthropogeography) is a branch of geography that focuses on studying patterns and processes that shape human society. It encompasses the human, political, cultural , social, and economic aspects. In industry, human geographers often work in city planning, public health, or business analysis. Various approaches to

There are several concepts related to technical geography that are considered central attributes of the discipline. In one paper, autocorrelation and frequency are listed as the concepts that technical geography is based upon. Central to technical geography are the technologies surrounding cartography and map production, which

This publication proposed how a field of scientific geography could be organized, and specified that "Phytogeography," "Zoogeography," and "Anthropogeography" could be areas where scientific principles could be applied. While this publication did not use
8379-569: The Earth radius was only 16.8 km less than the modern value of 6,356.7 km. In contrast to his predecessors, who measured the Earth's circumference by sighting the Sun simultaneously from two different locations, al-Biruni developed a new method of using trigonometric calculations based on the angle between a plain and mountain top, which yielded more accurate measurements of the Earth's circumference, and made it possible for it to be measured by

From the Hellenistic period ( c. 300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as a separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek . There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek

The influence of Immanuel Kant , Alexander von Humboldt , Carl Ritter , and Paul Vidal de la Blache can be seen as a major turning point in geography from philosophy to an academic subject. Geographers such as Richard Hartshorne and Joseph Kerski have regarded both Humboldt and Ritter as the founders of modern geography, as Humboldt and Ritter were
9234-469: The built environment and how humans create, view, manage, and influence space. Physical geography examines the natural environment and how organisms , climate, soil , water, and landforms produce and interact. The difference between these approaches led to the development of integrated geography , which combines physical and human geography and concerns the interactions between the environment and humans. Technical geography involves studying and developing

Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of a lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between
9576-467: The first law of geography , "everything is related to everything else, but near things are more related than distant things." This law summarizes the first assumption geographers make about the world. The discipline of geography, especially physical geography, and geology have significant overlap. In the past, the two have often shared academic departments at universities, a point that has led to conflict over resources. Both disciplines do seek to understand
9747-601: The interpolation (estimate) of unmeasured points. Geographers are making notable contributions to the method of quantitative techniques. Qualitative methods in geography are descriptive rather than numerical or statistical in nature. They add context to concepts, and explore human concepts like beliefs and perspective that are difficult or impossible to quantify. Human geography is much more likely to employ qualitative methods than physical geography. Increasingly, technical geographers are attempting to employ GIS methods to qualitative datasets. Qualitative cartography employs many of
9918-449: The lithosphere , atmosphere , hydrosphere , and biosphere . Places do not exist in a vacuum and instead have complex spatial relationships with each other, and place is concerned how a location is situated in relation to all other locations. As a discipline then, the term place in geography includes all spatial phenomena occurring at a location, the diverse uses and meanings humans ascribe to that location, and how that location impacts and

Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale. Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize

The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from the center of Greek scholarship, this division of people and language is quite similar to the results of modern archaeological-linguistic investigation. One standard formulation for

These terms all overlap to some degree, but at least one study indicates they differ substantially enough to continue using. The proliferation of these new terms may have been detrimental to their popularity, and it has been suggested that they were possibly created carelessly or hastily. This has led to some confusion, and properly defining
13338-609: The Man-Land or Human-Environment Interaction Tradition (sometimes referred to as Integrated geography ), the Area Studies or Regional Tradition, and the Earth Science Tradition. These concepts are broad sets of geography philosophies bound together within the discipline. They are one of many ways geographers organize the major sets of thoughts and philosophies within the discipline. In another approach to
13509-568: The United States military launched the first satellites to enable the modern Global Positioning System (GPS), and the system's full capability was made available to the general public in 2000. This facilitated a level of rapid acquisition of spatial coordinates that previously would have been expensive. Geographers began studying methods and applications for this data. In subsequent years, other countries have launched satellite constellations enabling Satellite navigation , including Russia's GLONASS , China's BeiDou Navigation Satellite System , and
13680-507: The United States, geomatics in France, and geoinformatics in Sweden. Three major technologies, remote sensing (RS), Geographic information systems (GIS), and the global positioning system (GPS) are highlighted as examples of technologies characterizing technical geography. Along with computers and GIS , new spatial data sources emerged during the quantitative revolution. Air photo technology
13851-472: The ability to model, analyze, and interpret spatial patterns and relationships, supporting various applications from environmental monitoring and urban planning to resource management and public health. By understanding and leveraging autocorrelation, geographers can make more informed decisions, improve the accuracy of their analyses, and contribute to solving real-world geographical problems. The techniques and technologies used to leverage this understanding are
14022-501: The abovementioned four traditions, geography is organized into applied branches. The UNESCO Encyclopedia of Life Support Systems organizes geography into the three categories of human geography , physical geography , and technical geography . Some publications limit the number of branches to physical and human, describing them as the principal branches. Geographers rarely focus on just one of these topics, often using one as their primary focus and then incorporating data and methods from
14193-401: The activity and use that occurs, has occurred, and will occur at the coordinates, and the meaning ascribed to the space by human individuals and groups. This can be extraordinarily complex, as different spaces may have different uses at different times and mean different things to different people. In physical geography, a place includes all of the physical phenomena that occur in space, including
14364-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has
14535-413: The areas covered by each term is an active field of research. One paper on the topic stated the following: With the appearance of the next new technologies, immediately, new proposals of new sciences, new subdisciplines, appear. Many authors with great ease announce the origination of a new science, frequently not caring for the proper justification of its name definition. The old definitions, developed in
14706-700: The associated concept of spatial autocorrelation, as central concepts to technical geography. The 20th century saw the rapid emergence of technologies such as computers, satellites, and the corresponding software to operate them. These technologies rapidly changed how geographers operated, and significant effort went into considering how best to incorporate them into the discipline. With these technologies came new disciplines and terms like analytical cartography , which focus on mathematical modeling and theoretical implications of cartography. These terms often compete and overlap with each other and often originate in separate countries, such as geographic information science in
14877-419: The augment when it was word-initial. In verbs with a preposition as a prefix, the augment is placed not at the start of the word, but between the preposition and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in
15048-463: The best word choice has been debated in the literature since at least the 1700s when Cave defended the use of technical geography over practical geography. However, many of these alternative terms or phrases are "grammatically awkward" and do not link the discipline explicitly as a branch of geography in the same way as technical geography. This is an area of active scholarly debate, and any word choice will be inevitably met with criticism by others using
15219-457: The book expanded on these key concepts by adding "Environmental systems," "Social Systems," "Nature," " Globalization ," "Development," and "Risk," demonstrating how challenging narrowing the field can be. Another approach used extensively in teaching geography are the Five themes of geography established by "Guidelines for Geographic Education: Elementary and Secondary Schools," published jointly by
15390-409: The branch is distinct in theory and methods. This publication defines technical geography with the following: "The Description confider'd as to Form is of three Sorts; The first exhibits the Earth, by a Draught or Delineation; the second by Tables, or Registers; and the third by Treties or Discourse. Hence Technical Geography may be divided into Representatory, Synoptical, and Explanatory." While when
15561-857: The branches of both human and physical geography. Historically, technical geography was focused on cartography and globe-making. Today, while technical geographers still develop and make maps, the Information Age has pushed the development of information management techniques to handle spatial data and support decision-makers. To this end, technical geographers often adapt technology and techniques from other disciplines to spatial problems rather than create original innovations, such as using computers to aid in cartography. They also explore adapting techniques developed for one area of geography to another, such as kriging , originally created for estimating gold ore distributions but now applied to topics such as real estate appraisal . Technical geography today
15732-404: The broad discipline of geography by serving as a set of unique methods for managing the interdisciplinary nature of the phenomena under investigation. While human and physical geographers use the techniques employed by technical geographers, technical geography is more concerned with the fundamental spatial concepts and technologies than the nature of the data. It is therefore closely associated with
15903-405: The case of Mars), its features, and phenomena that take place on it. For something to fall into the domain of geography, it generally needs some sort of spatial component that can be placed on a map , such as coordinates , place names, or addresses . This has led to geography being associated with cartography and place names. Although many geographers are trained in toponymy and cartology, this
16074-436: The concept of spacetime . Geography is subject to the laws of physics, and in studying things that occur in space, time must be considered. Time in geography is more than just the historical record of events that occurred at various discrete coordinates; but also includes modeling the dynamic movement of people, organisms, and things through space. Time facilitates movement through space, ultimately allowing things to flow through
16245-405: The concepts and techniques of technical geography. However, the methods and theory are distinct, and a technical geographer may be more concerned with the technological and theoretical concepts than the nature of the data. Further, a technical geographer may explore the relationship between the spatial technology and the end users to improve upon the technology and better understand the impact of
16416-400: The context of a map is the ratio between a distance measured on the map and the corresponding distance as measured on the ground. This concept is fundamental to the discipline of geography, not just cartography, in that phenomena being investigated appear different depending on the scale used. Scale is the frame that geographers use to measure space, and ultimately to understand a place. During
16587-406: The context of previous technological conditions, remain in the shadow of new technologies, and are not modernised. The lack of specific terminological conditions, determined boundaries, or scopes of such definition use, encourages one to define the next terms, and the next science and research disciplines. During the early days of the quantitative revolution, the term quantitative geography emerged as
16758-443: The country. To address this, geographers began to debate the merits of more scientific and methods-based approaches to the discipline and advocate for the benefits these methods had to other technical courses. Some, such as the preeminent cartographer George Jenks went as far as to suggest that cartography should be a separate academic discipline from geography entirely, even if only at a few academic institutions. This approach
16929-432: The culture in technical geography has introduced gender bias into geography departments as the discipline is disproportionately practiced by men and seen by some as more masculine. Nadine Schuurman states that while there is not one reason for this discrepancy, but may be related to the broader perception of science as a "masculine domain," and the perception that tools, like GIS, employed by technical geographers are part of
17100-615: The dialect of Sparta ), and Northern Peloponnesus Doric (including Corinthian ). All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects. After the conquests of Alexander the Great in the late 4th century BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek , but with influence from other dialects. This dialect slowly replaced most of
17271-530: The dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under
17442-399: The discipline concerned with handling geographic data or geographic information. In Canada, an effort was made to replace and absorb the term geodesy with geomatics; however, this was not successful, and globally, geodesy is generally considered "immutable" as a term. Geomatics was included in the UNESCO Encyclopedia of Life Support Systems under technical geography. In the late 1980s,
17613-464: The discipline during the quantitative revolution of the 1950s and 60s. These methods revitalized the discipline in many ways, allowing scientific testing of hypotheses and proposing scientific geographic theories and laws. The quantitative revolution heavily influenced and revitalized technical geography, and lead to the development of the subfield of quantitative geography. Cartography is the art, science, and technology of making maps. Cartographers study
17784-509: The discipline into a section containing content such as cartographic techniques and globes. There are several other terms, often used interchangeably with technical geography to subdivide the discipline, including "techniques of geographic analysis," "Geographic Information Technology," "Geography method's and techniques," " Geographic Information Science ," " geoinformatics ," " geomatics ," and "information geography". There are subtle differences to each concept and term; however, technical geography
17955-403: The discipline of computer science, while other sources place it under the branch of technical geography. Sources have noted that there is no universally accepted definition of geoinformatics. In the 1990s, the term Geographic Information Science (GIScience) was coined and popularized in the United States by geographer Michael Frank Goodchild to describe "the subset of information science that
18126-473: The discipline of geography dates back at least as far as 1749 to a book published by English printer Edward Cave at St John's Gate, Clerkenwell . This 1749 book was divided into four parts, one of which was named "containing technical geography", which focused on both globes and maps , including concepts of cartographic design , and projection . In this book, they chose to use the term "technical geography" rather than "practical geography" to clarify that
18297-518: The discipline of geography is normally concerned with the Earth, the term can also be informally used to describe the study of other worlds, such as the planets of the Solar System and even beyond. The study of systems larger than the Earth itself usually forms part of Astronomy or Cosmology . The study of other planets is usually called planetary science . Alternative terms such as areography (geography of Mars) have been employed to describe
18468-483: The discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography , remote sensing , interviews , and surveying . Geography is a systematic study of the Earth (other celestial bodies are specified, such as "geography of Mars", or given another name, such as areography in
18639-503: The discipline. Terms such as "techniques of geographic analysis", "geographic information technology", are used synonymously with the term within textbooks. As technology such as GIS began to dominate geography departments, the need to develop new curriculum to teach the fundamental concepts became apparent. In response to this in 2006 the UCGIS published Geographic Information Science and Technology Body of Knowledge (GISTBoK), building on
18810-471: The discipline. In contrast, geography's branches describe contemporary applied geographical approaches. Geography is an extremely broad field. Because of this, many view the various definitions of geography proposed over the decades as inadequate. To address this, William D. Pattison proposed the concept of the "Four traditions of Geography" in 1964. These traditions are the Spatial or Locational Tradition,
18981-510: The divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and the historical circumstances of the times imply that the overall groups already existed in some form. Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at
19152-660: The early criticisms of quantitative methods have been addressed with advances in technology, and persist due to ignorance of quantitative geography. Geographer William Graf noted that some physical geographers suspect several of the philosophies underlying critical geography are "fundamentally anti-scientific ." As new technologies and methods applied by geographers, such as spatial analysis, cartography/GIS, remote sensing, and GPS, are widely applicable to various disciplines, concern grew among geographers that these other non-geographers in other disciplines might become better at using them than geographers. In response to this, in 2006,
19323-404: The emerging category. These branches use similar geographic philosophies, concepts, and tools and often overlap significantly. Physical geography (or physiography) focuses on geography as an Earth science . It aims to understand the physical problems and the issues of lithosphere , hydrosphere , atmosphere , pedosphere , and global flora and fauna patterns ( biosphere ). Physical geography
19494-578: The first geographic information system , which allowed for storing and analysis of spatial data within a computer. These tools revolutionized the discipline of geography by contributing to the positivist scientific approaches to the discipline during the quantitative revolution. In the 1985 book Technological Transition in Cartography , Mark Monmonier speculated that computer cartography facilitated by GIS would largely replace traditional pen and paper cartography. Geographers began to heavily debate
19665-413: The first paper detailing the use of computers in the map-making process titled "Automation and Cartography" in 1959. While novel in terms of application, the process detailed by Tobler did not allow for storing or analyzing of geographic data. As computer technology progressed and better hardware became available, geographers rapidly adopted the technology to create maps. In 1960, Roger Tomlinson created
19836-435: The first steps in geographical map-making.". In 1908, geography professor George D. Hubbard included technical geography alongside regional geography , physical geography , and general research as courses that should be taught at in U.S. university geography departments. Hubbard specifies that technical geography refers to topics such as "mathematical or astronomical geography," as well as cartography. A 1910 publication in
20007-516: The first to establish geography as an independent scientific discipline. Over the past two centuries, the advancements in technology with computers have led to the development of geomatics and new practices such as participant observation and geostatistics being incorporated into geography's portfolio of tools. In the West during the 20th century, the discipline of geography went through four major phases: environmental determinism , regional geography ,
20178-400: The frequency of events changes across both space and time can reveal dynamic patterns. Spatial and temporal frequency are core concepts in technical geography because they are fundamental to understanding and analyzing geographic phenomena. Geography is inherently concerned with the distribution and dynamics of features across space and over time, and technical geography researches and develops
20349-416: The geographic space as their subject of study and research becomes a serious challenge for geographers. Geographers need to test and adapt to the new methods, models and procedures and implement them in all fields and development trends of Geography. By these also, Technical Geography as a new line of research and professional training becomes a necessity." Technical geography as a concept re-emerges to correct
20520-503: The geography of the regions they visited. Turkish geographer Mahmud al-Kashgari drew a world map on a linguistic basis, and later so did Piri Reis ( Piri Reis map ). Further, Islamic scholars translated and interpreted the earlier works of the Romans and the Greeks and established the House of Wisdom in Baghdad for this purpose. Abū Zayd al-Balkhī , originally from Balkh , founded
20691-448: The heights of mountains, depths of the valleys , and expanse of the horizon . He also discussed human geography and the planetary habitability of the Earth. He also calculated the latitude of Kath, Khwarezm , using the maximum altitude of the Sun, and solved a complex geodesic equation to accurately compute the Earth's circumference , which was close to modern values of the Earth's circumference. His estimate of 6,339.9 km for
20862-441: The historical trend in geography of adapting rather than developing new methods, technologies, and techniques for conducting geographic research by encouraging trained geographers to pursue this line of inquiry. While the use of the term "technical geography" itself has been debated since at least the 1700s, concepts within technical geography are often separated from the rest of geography when organizing and categorizing subfields in
21033-597: The history of the discipline is a series of competing narratives, with concepts emerging at various points across space and time. The oldest known world maps date back to ancient Babylon from the 9th century BC. The best known Babylonian world map, however, is the Imago Mundi of 600 BC. The map as reconstructed by Eckhard Unger shows Babylon on the Euphrates , surrounded by a circular landmass showing Assyria , Urartu , and several cities, in turn surrounded by
21204-433: The ideas and philosophies advanced during the quantitative revolution, particularly positivism and the emphasis on quantitative methods, the term critical geography was applied to ideological and theoretical criticisms of the methods and ideas of technical geographers. Other geographers, such as Yi-Fu Tuan , have criticized that geography for moving away from the abstract, unquantifiable aspects of place that are essential to
21375-494: The late 1800s, the term "technical geography" was in use to some capacity in American public education and academia. For example, an article in the 1889 edition of the journal School and Home Education stated that "we never hear teachers questioning whether technical geography shall be taught in the schools" and defined the term "technical" to mean "especially appropriate to any art or science." An 1890 publication advertised that
21546-399: The laws of nature and to mark their influences upon man. This is 'a description of the world'—that is Geography. In a word, Geography is a Science—a thing not of mere names but of argument and reason, of cause and effect. Geography as a discipline can be split broadly into three main branches: human geography , physical geography , and technical geography . Human geography largely focuses on
21717-461: The ninth century, often mixing them with elements of traditional Islamic cartography. For example, the Kitab al-Buldan , written by Ibn al-Faqih between 902 and 903 C.E., was described by Henri Massé as "technical geography [including] themes of adab ." Technical geography as a term is more than place name recollection and toponymy ; it involves spatial relationships between points and theory. By
21888-508: The older dialects, although the Doric dialect has survived in the Tsakonian language , which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek . By about the 6th century AD, the Koine had slowly metamorphosed into Medieval Greek . Phrygian is an extinct Indo-European language of West and Central Anatolia , which
22059-412: The other branches. Often, geographers are asked to describe what they do by individuals outside the discipline and are likely to identify closely with a specific branch, or sub-branch when describing themselves to lay people. Human geography studies people and their communities, cultures, economies, and environmental interactions by studying their relations with and across space and place. Physical geography
22230-456: The peer-reviewed journal Geographia Technica was established to serve as an outlet for research employing quantitative, technical, and scientific methods within geography. In a 2016 paper within this journal, Ionel Haidu stated: "The risk is that non-geographers mastering these methods analyze the spatiotemporal data and information better than the geographers. That is why the need to deal with competition induced by other sciences claiming
22401-487: The perfect stem eilēpha (not * lelēpha ) because it was originally slambanō , with perfect seslēpha , becoming eilēpha through compensatory lengthening. Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i . A nasal stop appears after the reduplication in some verbs. The earliest extant examples of ancient Greek writing ( c. 1450 BC ) are in
22572-476: The place of GIS in geography, with some rejecting its methods and others heavily advocating for it. In response to critics, British geographer Stan Openshaw stated: ...if geographers reject GIS then it could fundamentally affect the outside world's perception of what geography is all about. Certainly, these external perceptions may well be based on a picture of geography as it once was, but nevertheless they cannot be ignored. "How could they be so foolish as to disown
22743-402: The prediction of eclipses. The foundations of geography can be traced to ancient cultures, such as the ancient, medieval, and early modern Chinese . The Greeks , who were the first to explore geography as both art and science, achieved this through Cartography , Philosophy , and Literature , or through Mathematics . There is some debate about who was the first person to assert that the Earth
22914-419: The quantitative revolution was the emergence of early computers. The interdisciplinary nature of geography forces geographers to look at developments in other fields, and geographers tend to observe and adapt technological innovations from other disciplines rather than developing unique technologies to conduct geographic studies. More than a decade after the first computers were developed, Waldo Tobler published
23085-449: The quantitative revolution, geography shifted to an empirical law-making ( nomothetic ) approach. Several laws of geography have been proposed since then, most notably by Waldo Tobler and can be viewed as a product of the quantitative revolution. In general, some dispute the entire concept of laws in geography and the social sciences. These criticisms have been addressed by Tobler and others, such as Michael Frank Goodchild . However, this
23256-472: The relationship between physical and human phenomena and their spatial patterns. Names of places...are not geography...To know by heart a whole gazetteer full of them would not, in itself, constitute anyone a geographer. Geography has higher aims than this: it seeks to classify phenomena (alike of the natural and of the political world, in so far as it treats of the latter), to compare, to generalize, to ascend from effects to causes, and, in doing so, to trace out
23427-434: The same software and techniques as quantitative cartography. It may be employed to inform on map practices, or to visualize perspectives and ideas that are not strictly quantitative in nature. An example of a form of qualitative cartography is a Chorochromatic map of nominal data, such as land cover or dominant language group in an area. Another example is a deep map , or maps that combine geography and storytelling to produce
23598-497: The same, or similar, concepts as technical geography. Some of the discrepancy in terminology is due to different cultures and languages having their own method of organization; for example, the term "information geography" is popular in research from China to describe similar concepts. It is closely associated with and sometimes used interchangeably with, the subfields of geographic information science and geoinformatics . Each term has slightly differing definitions and scopes, and
23769-558: The scientific method. In 1960, Bernard Dubuisson coined the term "géomatique" in French. English-speaking Canadians Pierre Gagnon and David Coleman translated the term as "geomatics", which was popularized in Canada through the 1980s and early 1990s. Today, it is defined by the ISO/TC 211 , an International Organization for Standardization committee focused on geographic information, as
23940-531: The second and replaced with another. A few of the proposed laws of geography are below: Additionally, several variations or amendments to these laws exist within the literature, although not as well supported. For example, one paper proposed an amended version of Tobler's first law of geography, referred to in the text as the Tobler–von Thünen law , which states: "Everything is related to everything else, but near things are more related than distant things, as
24111-417: The similarity between observations as a function of the time lag or spatial distance between them. Autocorrelation can be positive (indicating that similar values cluster together) or negative (indicating that dissimilar values are near each other). Spatial autocorrelation involves the correlation of a variable with itself across different spatial locations. Temporal autocorrelation involves the correlation of
24282-441: The spatial context within which historical events unfold. The physical geographic features of a region, such as its landforms, climate, and resources, shape human settlements, trade routes, and economic activities, which in turn influence the course of historical events. Thus, a historian must have a strong foundation in geography. Historians employ the techniques of technical geographers to create historical atlases and maps. While
24453-671: The spatial relationships is called geographic information science (GISc). Remote sensing is the art, science, and technology of obtaining information about Earth's features from measurements made at a distance. Remotely sensed data can be either passive, such as traditional photography , or active, such as LiDAR . A variety of platforms can be used for remote sensing, including satellite imagery , aerial photography (including consumer drones), and data obtained from hand-held sensors. Products from remote sensing include Digital elevation model and cartographic base maps. Geographers increasingly use remotely sensed data to obtain information about
24624-537: The spatial tradition of geography while being applied to the other two major branches. A technical geographer might work as a GIS analyst, a GIS developer working to make new software tools, or create general reference maps incorporating human and natural features. All geographic research and analysis start with asking the question "where," followed by "why there." Geographers start with the fundamental assumption set forth in Tobler's first law of geography , that "everything
24795-399: The study of human geography have also arisen through time and include: Technical geography concerns studying and developing tools, techniques, and statistical methods employed to collect, analyze, use, and understand spatial data. Technical geography is the most recently recognized, and controversial, of the branches. Its use dates back to 1749, when a book published by Edward Cave organized
24966-494: The study of other celestial objects. Ultimately, geography may be considered a subdiscipline within planetary science. Ancient Greek Ancient Greek ( Ἑλληνῐκή , Hellēnikḗ ; [hellɛːnikɛ́ː] ) includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek ( c. 1400–1200 BC ), Dark Ages ( c. 1200–800 BC ),
25137-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies
25308-533: The techniques and methods of handling spatial information were primarily focused on supporting human or physical geography, rather than a subject of study itself. World War II , which saw the extensive use of cartography and air photos, revolutionized these techniques and brought a new focus on the benefits they offered. In the years before the quantitative revolution, geography was generally fragmented and focused on descriptive approaches, and many United States universities were eliminating geography departments around
25479-518: The techniques to deal with this data. Cartographic generalization is the process of simplifying the representation of geographical information on maps, making complex data more understandable and useful for specific purposes or scales. This process involves selectively reducing the detail of features to prevent clutter and ensure that the map communicates the intended information effectively. The need for generalization arises because maps often depict large areas and scales, where including every detail
25650-708: The technology on human behavior. Thus, the spatial data types a technical geographer employs may vary widely, including human and physical geography topics, with the common thread being the techniques and philosophies employed. To accomplish this, technical geographers often create their own software or scripts, which can then be applied more broadly by others. They may also explore applying techniques developed for one application to another unrelated topic, such as applying Kriging , originally developed for mining, to disciplines as diverse as real-estate prices. In teaching technical geography, instructors often need to fall back on examples from human and physical geography to explain
25821-455: The term geoinformatics was coined by Swedish scientist Kjell Samuelson and later defined in the 1990s as the science of integrating spatial data derived from various technologies, such as remote sensing, GPS, and GIS. It was later defined by geographer Michael DeMers to include processing of spatial data through the use of computers. This term has been described as being outside the branch of geography entirely and instead placed fully under
25992-421: The term GIScience, including questioning if it can be considered a science. Many geographers, including Michael Goodchild, continue to advance the use of the term today. In the same 1749 publication in which Cave discussed technical geography (Geography reformed: a new system of general geography, according to an accurate analysis of the science in four parts. The whole illustrated with notes) critical geography
26163-415: The term technical geography first entered the English lexicon may be difficult to ascertain, technical geography as a concept crosses cultures, and techniques date back to the origins of cartography, surveying, and remote sensing . Eratosthenes has been called the "founder of mathematical geography," and his activities are described as "little different from what we expect of a technical geographer." Within
26334-503: The term technical geography in its description, several later publications explicitly link scientific and technical geography. By 1917, technical geography was included among courses taught at some British schools, alongside mathematics, chemistry, and other natural sciences. As techniques and concepts in technical geography advanced, geographers began to lament the lack of understanding and use of more advanced geographic concepts in society and law. Specifically, this became an issue during
26505-583: The theoretical concepts. While technical geography mostly works with quantitative data, the techniques and technology can be applied to qualitative geography , differentiating it from quantitative geography . Within the branch of technical geography are the major and overlapping subbranches of geographic information science , geomatics , and geoinformatics . Technical geography is highly theoretical and focuses on developing and testing methods and technologies for handling spatial-temporal data. These technologies are then applied to datasets and problems within
26676-467: The time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to the historical Dorians . The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with
26847-572: The times when geography became recognized as a discrete academic discipline , and became part of a typical university curriculum in Europe (especially Paris and Berlin ). The development of many geographic societies also occurred during the 19th century, with the foundations of the Société de Géographie in 1821, the Royal Geographical Society in 1830, Russian Geographical Society in 1845, American Geographical Society in 1851,
27018-491: The tools and techniques used by geographers, such as remote sensing, cartography, and geographic information system. Narrowing down geography to a few key concepts is extremely challenging, and subject to tremendous debate within the discipline. In one attempt, the 1st edition of the book "Key Concepts in Geography" broke down this into chapters focusing on "Space," "Place," "Time," "Scale," and "Landscape." The 2nd edition of
27189-440: The understanding of geography. In the history of geography since the quantitative revolution, theorists from critical geography are often viewed as in direct confrontation with those of technical and quantitative geography. Some, such as Peter Gould , argued that these criticisms were largely due to the difficulty in learning the emerging novel technologies. Some geographers, including Stewart Fotheringham , argue that many of
27360-456: The very core of their discipline?" With the emergence of GIS, researchers rapidly began to explore methods to use the technology for various geographic problems. This led some geographers to declare the study of the computer-based methods their own science within geography. GIS serves as the primary technology driving the field of geodesign by enabling real-time feedback in considering geography and landscape with community planning. In 1978,
27531-416: The view of the world as a photograph, with everything frozen in place when the coordinates were recorded. Today, geographers are trained to recognize the world as a dynamic space where all processes interact and take place, rather than a static image on a map. Place is one of the most complex and important terms in geography. In human geography, place is the synthesis of the coordinates on the Earth's surface,
27702-406: The word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography ) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to
27873-480: Was Aeolic. For example, fragments of the works of the poet Sappho from the island of Lesbos are in Aeolian. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric ), Southern Peloponnesus Doric (including Laconian ,
28044-452: Was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in
28215-667: Was considered an important part of the process within geography to correct errors on maps and other products to improve models of the world. In the 1970s, critical geography took on the framework of critical theory and Marxist philosophy , and became an umbrella uniting various theoretical frameworks in geography, including Marxist geography , feminist geography , and radical geography (a branch of geography that advocates that geographic research should focus on social issues transforming society). These frameworks were mostly advanced mostly by human geographers, leading to an observed gap between human and physical geographers. In response to
28386-614: Was finding the latitude and longitude of a geographic location. While the problem of latitude was solved long ago, but that of longitude remained; agreeing on what zero meridians should be was only part of the problem. It was left to John Harrison to solve it by inventing the chronometer H-4 in 1760, and later in 1884 for the International Meridian Conference to adopt by convention the Greenwich meridian as zero meridians. The 18th and 19th centuries were
28557-451: Was proposed by Waldo Tobler in a 1970 paper, and more have been proposed since. Some geographers argue against the idea that laws in geography are necessary or even valid. These criticisms have been addressed by Tobler and others. Examples of these laws include Tobler's first law of geography , Tobler's second law of geography , and Arbia's law of geography . French geographer Ionel Haidu noted Tobler's first law of geography, and
28728-546: Was published by Bernhardus Varenius , which was later edited and republished by others including Isaac Newton . This textbook sought to integrate new scientific discoveries and principles into classical geography and approach the discipline like the other sciences emerging, and is seen by some as the division between ancient and modern geography in the West. The Geographia Generalis contained both theoretical background and practical applications related to ship navigation. The remaining problem facing both explorers and geographers
28899-523: Was regarded as the most skilled when it came to mapping cities and measuring the distances between them, which he did for many cities in the Middle East and the Indian subcontinent . He often combined astronomical readings and mathematical equations to develop methods of pin-pointing locations by recording degrees of latitude and longitude . He also developed similar techniques when it came to measuring
29070-549: Was shunned by more traditional geographers, who viewed it as a deviation from how geographers had always viewed and interacted with maps. While the best approach to the technical aspect of geography was heavily debated among geographers, geography departments at universities across the United States began to teach a more scientific approach to geography. The quantitative revolution is primarily credited with shifting descriptive, or idiographic , geography to an empirical law-making, or nomothetic , geography. The first of these laws
29241-528: Was widely used in World War I and, in subsequent years, was applied to civilian endeavors. A 1941 textbook titled "Aerophotography and Aerosurverying" stated the following in the first line of its preference: "There is no longer any need to preach for aerial photography-not in the United States- for so widespread has become its use and so great its value that even the farmer who plants his fields in
