98-516: A map legend on the margin of the map, or on a separately published characteristic sheet. Some cartographers prefer to make the map cover practically the entire screen or sheet of paper, leaving no room "outside" the map for information about the map as a whole. These cartographers typically place such information in an otherwise "blank" region "inside" the map— cartouche , map legend, title, compass rose , bar scale , etc. In particular, some maps contain smaller maps inset into otherwise blank areas of

147-454: A ratio , such as 1:10,000, which means that 1 unit of measurement on the map corresponds to 10,000 of that same unit on the ground. The scale statement can be accurate when the region mapped is small enough for the curvature of the Earth to be neglected, such as a city map . Mapping larger regions, where the curvature cannot be ignored, requires projections to map from the curved surface of

196-470: A broad understanding of the location and features of an area. The reader may gain an understanding of the type of landscape, the location of urban places, and the location of major transportation routes all at once. Polish general Stanisław Maczek had once been shown an impressive outdoor map of land and water in the Netherlands demonstrating the working of the waterways (which had been an obstacle to

245-464: A map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements , they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have

294-399: A particular purpose for an intended audience. Designing a map involves bringing together a number of elements and making a large number of decisions. The elements of design fall into several broad topics, each of which has its own theory, its own research agenda, and its own best practices. That said, there are synergistic effects between these elements, meaning that the overall design process

343-495: A right angle from the prime direction, that are closest to the rising and setting, respectively, of the sun (or moon). Being the "default" direction on the compass, north is referred to frequently in Western popular culture. Some examples include: Map A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space . A map may be annotated with text and graphics. Like any graphic,

441-417: A very long tradition and have existed from ancient times. The word "map" comes from the medieval Latin : Mappa mundi , wherein mappa meant 'napkin' or 'cloth' and mundi 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through

490-485: Is a navigational term referring to the direction northwards along the grid lines of a map projection . The visible rotation of the night sky around the visible celestial pole provides a vivid metaphor of that direction corresponding to "up". Thus the choice of the north as corresponding to "up" in the northern hemisphere, or of south in that role in the southern, is, before worldwide communication, anything but an arbitrary one - at least for night-time astronomers. (Note:

539-510: Is called a cartographer . Road maps are perhaps the most widely used maps today. They are a subset of navigational maps, which also include aeronautical and nautical charts , railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by municipalities , utilities, tax assessors, emergency services providers, and other local agencies. Many national surveying projects have been carried out by

588-462: Is derived from Latin oriens , meaning east. In the Middle Ages many maps, including the T and O maps , were drawn with east at the top (meaning that the direction "up" on the map corresponds to East on the compass). The most common cartographic convention nowadays is that north is at the top of a map. Maps not oriented with north at the top: Many maps are drawn to a scale expressed as

637-569: Is different from Wikidata All article disambiguation pages All disambiguation pages North The word north is related to the Old High German nord , both descending from the Proto-Indo-European unit * ner- , meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word borealis comes from

686-588: Is not just working on each element one at a time, but an iterative feedback process of adjusting each to achieve the desired gestalt . Maps of the world or large areas are often either 'political' or 'physical'. The most important purpose of the political map is to show territorial borders ; the purpose of the physical map is to show features of geography such as mountains, soil type, or land use including infrastructures such as roads, railroads, and buildings. Topographic maps show elevations and relief with contour lines or shading. Geological maps show not only

735-467: Is used by agencies around the world, as diverse as wildlife conservationists and militaries. Even when GIS is not involved, most cartographers now use a variety of computer graphics programs to generate new maps. Interactive, computerized maps are commercially available, allowing users to zoom in or zoom out (respectively meaning to increase or decrease the scale), sometimes by replacing one map with another of different scale, centered where possible on

784-566: The Arctic Circle the Sun never shines from the north. North is sometimes abbreviated as N . By convention , the top or upward-facing side of a map is north. To go north using a compass for navigation , set a bearing or azimuth of 0° or 360°. Traveling directly north traces a meridian line upwards. North is specifically the direction that, in Western culture , is considered

833-641: The Greek boreas "north wind, north", which, according to Ovid , was personified as the wind-god Boreas , the father of Calais and Zetes . Septentrionalis is from septentriones , "the seven plow oxen", a name of Ursa Major . The Greek ἀρκτικός ( arktikós ) is named for the same constellation, and is the source of the English word Arctic . Other languages have other derivations. For example, in Lezgian , kefer can mean both "disbelief" and "north", since to

882-407: The fundamental direction: Magnetic north is of interest because it is the direction indicated as north on a properly functioning (but uncorrected) magnetic compass . The difference between it and true north is called the magnetic declination (or simply the declination where the context is clear). For many purposes and physical circumstances, the error in direction that results from ignoring

931-425: The geoid to a two-dimensional picture. Projection always distorts the surface. There are many ways to apportion the distortion, and so there are many map projections. Which projection to use depends on the purpose of the map. The various features shown on a map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. Those signs are usually explained in

980-715: The British Columbia Pavilion at the Pacific National Exhibition (PNE) in Vancouver from 1954 to 1997 it was viewed by millions of visitors. The Guinness Book of Records cites the Challenger Map as the largest of its kind in the world. The map in its entirety occupies 6,080 square feet (1,850 square metres) of space. It was disassembled in 1997; there is a project to restore it in a new location. The Relief map of Guatemala

1029-453: The Earth to the plane. The impossibility of flattening the sphere to the plane without distortion means that the map cannot have a constant scale. Rather, on most projections, the best that can be attained is an accurate scale along one or two paths on the projection. Because scale differs everywhere, it can only be measured meaningfully as point scale per location. Most maps strive to keep point scale variation within narrow bounds. Although

1078-466: The Polish forces progress in 1944). This had inspired Maczek and his companions to create Great Polish Map of Scotland as a 70-ton permanent three-dimensional reminder of Scotland's hospitality to his compatriots. In 1974, the coastline and relief of Scotland were laid out by Kazimierz Trafas, a Polish student geographer-planner, based on existing Bartholomew Half-Inch map sheets. Engineering infrastructure

1127-520: The connectivity is significant. The London Underground map and similar subway maps around the world are a common example of these maps. General-purpose maps provide many types of information on one map. Most atlas maps, wall maps, and road maps fall into this category. The following are some features that might be shown on general-purpose maps: bodies of water, roads, railway lines, parks, elevations, towns and cities, political boundaries, latitude and longitude, national and provincial parks. These maps give

1176-549: The dates of onset of a given phenomenon (for example, the first frost and appearance or disappearance of the snow cover) or the date of a particular value of a meteorological element in the course of a year (for example, passing of the mean daily air temperature through zero). Isolines of the mean numerical value of wind velocity or isotachs are drawn on wind maps (charts); the wind resultants and directions of prevailing winds are indicated by arrows of different lengths or arrows with different plumes; lines of flow are often drawn. Maps of

1225-445: The differences between the mean temperatures of the warmest and coldest month). Isanomals are drawn on maps of anomalies (for example, deviations of the mean temperature of each place from the mean temperature of the entire latitudinal zone). Isolines of frequency are drawn on maps showing the frequency of a particular phenomenon (for example, the annual number of days with a thunderstorm or snow cover). Isochrones are drawn on maps showing

1274-488: The distinction is tolerable; in others a mental or instrument compensation, based on assumed knowledge of the applicable declination, can solve all the problems. But simple generalizations on the subject should be treated as unsound, and as likely to reflect popular misconceptions about terrestrial magnetism . Maps intended for usage in orienteering by compass will clearly indicate the local declination for easy correction to true north. Maps may also indicate grid north , which

1323-405: The distribution of pressure at different standard altitudes—for example, at every kilometer above sea level—or by maps of baric topography on which altitudes (more precisely geopotentials) of the main isobaric surfaces (for example, 900, 800, and 700 millibars) counted off from sea level are plotted. The temperature, humidity, and wind on aero climatic maps may apply either to standard altitudes or to

1372-435: The earth's surface and in the upper layers of the atmosphere. Climatic maps show climatic features across a large region and permit values of climatic features to be compared in different parts of the region. When generating the map, spatial interpolation can be used to synthesize values where there are no measurements, under the assumption that conditions change smoothly. Climatic maps generally apply to individual months and

1421-476: The earth's surface into climatic zones and regions according to some classification of climates, are a special kind of climatic map. Climatic maps are often incorporated into climatic atlases of varying geographic ranges (globe, hemispheres, continents, countries, oceans) or included in comprehensive atlases. Besides general climatic maps, applied climatic maps and atlases have great practical value. Aero climatic maps, aero climatic atlases, and agro climatic maps are

1470-428: The edges of the map. Further inaccuracies may be deliberate. For example, cartographers may simply omit military installations or remove features solely to enhance the clarity of the map. For example, a road map may not show railroads, smaller waterways, or other prominent non-road objects, and even if it does, it may show them less clearly (e.g. dashed or dotted lines/outlines) than the main roads. Known as decluttering,

1519-480: The left) of Europe has been distorted to show population distribution, while the rough shape of the continent is still discernible. Another example of distorted scale is the famous London Underground map . The geographic structure is respected but the tube lines (and the River Thames ) are smoothed to clarify the relationships between stations. Near the center of the map, stations are spaced out more than near

1568-458: The main isobaric surfaces. Isolines are drawn on maps of such climatic features as the long-term mean values (of atmospheric pressure, temperature, humidity, total precipitation, and so forth) to connect points with equal values of the feature in question—for example, isobars for pressure, isotherms for temperature, and isohyets for precipitation. Isoamplitudes are drawn on maps of amplitudes (for example, annual amplitudes of air temperature—that is,

1617-462: The map: for example: The design and production of maps is a craft that has developed over thousands of years, from clay tablets to Geographic information systems . As a form of Design , particularly closely related to Graphic design , map making incorporates scientific knowledge about how maps are used, integrated with principles of artistic expression, to create an aesthetically attractive product, carries an aura of authority, and functionally serves

1666-521: The military, such as the British Ordnance Survey : a civilian government agency, internationally renowned for its comprehensively detailed work. The location information showed by maps may include contour lines , indicating constant values of elevation , temperature, rainfall, etc. The orientation of a map is the relationship between the directions on the map and the corresponding compass directions in reality. The word " orient "

In addition maps of other bodies such as the Moon and other planets are technically not geo graphical maps. Floor maps are also spatial but not necessarily geospatial. Diagrams such as schematic diagrams and Gantt charts and tree maps display logical relationships between items, rather than geographic relationships. Topological in nature, only

1764-575: The north of the Muslim Lezgian homeland there are areas formerly inhabited by non-Muslim Caucasian and Turkic peoples. In many languages of Mesoamerica , north also means "up". In Romanian the old word for north is mĭazănoapte , from Latin mediam noctem meaning midnight and in Hungarian is észak , which is derived from éjszaka ("night"), since between the Tropic of Cancer and

1813-429: The physical surface, but characteristics of the underlying rock, fault lines, and subsurface structures. From the last quarter of the 20th century, the indispensable tool of the cartographer has been the computer. Much of cartography, especially at the data-gathering survey level, has been subsumed by geographic information systems (GIS). The functionality of maps has been greatly advanced by technology simplifying

1862-413: The practice makes the subject matter that the user is interested in easier to read, usually without sacrificing overall accuracy. Software-based maps often allow the user to toggle decluttering between ON, OFF, and AUTO as needed. In AUTO the degree of decluttering is adjusted as the user changes the scale being displayed. Geographic maps use a projection to translate the three-dimensional real surface of

1911-571: The same point. In-car global navigation satellite systems are computerized maps with route planning and advice facilities that monitor the user's position with the help of satellites. From the computer scientist's point of view, zooming in entails one or more of: For example: The maps that reflect the territorial distribution of climatic conditions based on the results of long-term observations are called climatic maps . These maps can be compiled both for individual climatic features (temperature, precipitation, humidity) and for combinations of them at

1960-454: The scale statement is nominal it is usually accurate enough for most purposes unless the map covers a large fraction of the Earth. At the scope of a world map, scale as a single number is practically meaningless throughout most of the map. Instead, it usually refers to the scale along the equator. Some maps, called cartograms , have the scale deliberately distorted to reflect information other than land area or distance. For example, this map (at

2009-430: The southern hemisphere lacks a prominent visible analog to the northern Pole Star .) On the contrary, Chinese and Islamic cultures considered south as the proper "top" end for maps . In the cultures of Polynesia , where navigation played an important role, winds - prevailing local or ancestral - can define cardinal points . In Western culture : North is quite often associated with colder climates because most of

2058-584: The sun rises" and "where it sets". Except on the Equator, however, these definitions, taken together, would imply that Reasonably accurate folk astronomy, such as is usually attributed to Stone Age peoples or later Celts , would arrive at east and west by noting the directions of rising and setting (preferably more than once each) and choosing as prime direction one of the two mutually opposite directions that lie halfway between those two. The true folk-astronomical definitions of east and west are "the directions,

2107-402: The superimposition of spatially located variables onto existing geographic maps. Having local information such as rainfall level, distribution of wildlife, or demographic data integrated within the map allows more efficient analysis and better decision making. In the pre-electronic age such superimposition of data led Dr. John Snow to identify the location of an outbreak of cholera . Today, it

The Arctic Circle passes through the Arctic Ocean , Norway , Sweden , Finland , Russia , the United States ( Alaska ), Canada ( Yukon , Northwest Territories and Nunavut ), Denmark ( Greenland ) and Iceland . While the choice of north over south as prime direction reflects quite arbitrary historical factors, east and west are not nearly as natural alternatives as first glance might suggest. Their folk definitions are, respectively, "where

2205-491: The world. The earliest surviving maps include cave paintings and etchings on tusk and stone. Later came extensive maps produced in ancient Babylon , Greece and Rome , China , and India . In their simplest forms, maps are two-dimensional constructs. Since the Classical Greek period , however, maps also have been projected onto globes . The Mercator Projection , developed by Flemish geographer Gerardus Mercator ,

2254-424: The year as a whole, sometimes to the four seasons, to the growing period, and so forth. On maps compiled from the observations of ground meteorological stations, atmospheric pressure is converted to sea level. Air temperature maps are compiled both from the actual values observed on the surface of the Earth and from values converted to sea level. The pressure field in the free atmosphere is represented either by maps of

2303-410: The zonal and meridional components of wind are frequently compiled for the free atmosphere. Atmospheric pressure and wind are usually combined on climatic maps. Wind roses, curves showing the distribution of other meteorological elements, diagrams of the annual course of elements at individual stations, and the like are also plotted on climatic maps. Maps of climatic regionalization, that is, division of

2352-599: Was put in place to surround it with a sea of water and at the General's request some of the main rivers were even arranged to flow from headwaters pumped into the mountains. The map was finished in 1979, but had to be restored between 2013 and 2017. The Challenger Relief Map of British Columbia is a hand-built topographic map of the province, 80 feet by 76 feet. Built by George Challenger and his family from 1947 to 1954, it features all of B.C.'s mountains, lakes, rivers and valleys in exact-scaled topographical detail. Residing in

2401-420: Was widely used as the standard for two-dimensional world maps until the late 20th century, when more accurate projections were more widely used. Mercator also was the first to use and popularize the concept of the atlas : a collection of maps. Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography ), and one who makes maps
