21-469: The lake must have been 340 hectares in size and 3 to 4 meters deep, before it was drained in 1627, together with two other Waterland lakes; the Belmer and Broeker lake. The lakes were probably formed due to the erosion of worn-down peatland (the ' water wolf '). The soil of the polder - no marine clay - turned out to be only suitable as pasture . The western part of the ring ditch became part of

42-679: A dash ; for example, 1-21-00.26 ha would mean 1 hectare, 21 ares, and 0.26 centiares (12,100.26 m ). The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure: In 1960, when the metric system was updated as the International System of Units (SI), the are did not receive international recognition. The International Committee for Weights and Measures ( CIPM ) makes no mention of

63-404: A double prefix is non-standard. The decimilliare is (100 mm) or roughly a four-inch-by-four-inch square. The centiare is one square metre. The deciare (rarely used) is ten square metres. The are ( / ɑːr / or / ɛər / ) is a unit of area, equal to 100 square metres ( 10 m × 10 m ), used for measuring land area. It was defined by older forms of the metric system , but

84-439: A few other units including the are (and implicitly the hectare ) whose use was limited to the measurement of land. The names centiare , deciare , decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are . The decimilliare (dma, sometimes seen in cadastre area evaluation of real estate plots) is 1 ⁄ 10,000 are or one square decimetre. Such usage of

105-550: A measure of land area. The names of the older land measures of similar size are usually used, redefined as exactly one decare: The most commonly used units are in bold . One hectare is also equivalent to: The Unicode character U+33CA ㏊ SQUARE HA , in the CJK Compatibility block, is intended for compatibility with pre-existing East Asian character codes. It is not intended for use in alphabetic contexts. U+3336 ㌶ SQUARE HEKUTAARU

126-439: Is a non-SI metric unit of area equal to a square with 100- metre sides (1 hm ), that is, 10,000 square metres (10,000 m ), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectares and one hectare contains about 2.47 acres. In 1795, when the metric system was introduced, the are was defined as 100 square metres , or one square decametre , and

147-456: Is now outside the modern International System of Units (SI). It is still commonly used in speech to measure real estate, in particular in Indonesia, India, and in various European countries. In Russian and some other languages of the former Soviet Union , the are is called sotka (Russian: сотка : 'a hundred', i.e. 100 m or 1 ⁄ 100 hectare). It is used to describe

189-633: The Noordhollandsch Kanaal (Great North Holland Canal ) in 1824. A year after, in 1825, the dyke at Durgerdam collapsed and the Waterland and the Buikslotermeer were completely flooded. The last time the polder flooded was in 1916. The Buikslotermeerpolder was located in the former municipalities of Nieuwendam and Buiksloot . Both merged into the municipality of Amsterdam in 1921, as part of Amsterdam Noord . Hereafter,

210-725: The Olof Palmeplein ; where the Boven 't Y shopping center and the district office are located. To the west and south of the Buikslotermeerplein are the districts of Loenermark (often called the 'banana flats') and the Plan van Gool . East of the Buikslotermeerplein is the Waterlandpleinbuurt , formerly named Nieuwendam-Noord . The Research and Statistics department of the municipality of Amsterdam uses

231-641: The are in the 2019 edition of the SI brochure, but classifies the hectare as a "Non-SI unit accepted for use with the International System of Units". In 1972, the European Economic Community (EEC) passed directive 71/354/EEC, which catalogued the units of measure that might be used within the Community. The units that were catalogued replicated the recommendations of the CGPM, supplemented by

252-465: The SI, being equivalent to a square hectometre. It is widely used throughout the world for the measurement of large areas of land, and it is the legal unit of measure in domains concerned with land ownership, planning, and management , including law ( land deeds ), agriculture, forestry , and town planning throughout the European Union , New Zealand and Australia (since 1970). However,

273-1010: The United Kingdom, the United States, Myanmar (Burma), and to some extent Canada, use the acre instead of the hectare for measuring surface or land area. Some countries that underwent a general conversion from traditional measurements to metric measurements (e.g. Canada) required a resurvey when units of measure in legal descriptions relating to land were converted to metric units. Others, such as South Africa, published conversion factors which were to be used particularly "when preparing consolidation diagrams by compilation". In many countries, metrification redefined or clarified existing measures in terms of metric units. The following legacy units of area have been redefined as being equal to one hectare: In Mexico, land area measurements are commonly given as combinations of hectares, ares, and centiares. These are commonly written separated by

294-614: The combination 'Buikslotermeer' for its reports, which covers the entire polder. A big portion of the polder is part of the Centrum Amsterdam Noord planning area, which provided new housing, schools, a library and theatre, expansion of the shopping mall and the construction of subway station North at the North-South line at the traffic median of the Nieuwe Leeuwarderweg.

315-514: The dekare/decare daa (1,000 m ) and are (100 m ) are not officially "accepted for use", they are still used in some contexts. The hectare ( / ˈ h ɛ k t ɛər , - t ɑː r / ), although not a unit of SI, is the only named unit of area that is accepted for use with SI units . The name was coined in French, from the Latin ārea . In practice the hectare is fully derived from

336-478: The hectare (" hecto- " + "are") was thus 100 ares or 1 ⁄ 100  km (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units ( SI ), the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though

357-635: The polder retained its agricultural nature. Amsterdam's General Expansion Plan ("Algemeen Uitbreidingsplan") from 1934 did not provide housing in Amsterdam Noord . However, in the 1930s the Noorderbegraafplaats (a cemetery ) was built in the northwestern part. A change in the Algemeen Uitbreidingsplan in 1958 meant that the polder was built up at a rapid pace in the 1960s. Early 20th century buildings along

378-464: The polder this varies to -4.8 to -5.2 m below NAP. The ground level varies from -3.5 to -4.5 m NAP. Typical is the elevated construction of all roads crossing the polder. Notably, the raised slopes of the A10 ring road and Nieuwe Leeuwarderweg divide the polder into four sections. A water treatment plant is located in the northwestern section, the northeastern section has a golf course . Within

399-617: The ring road, west of the Nieuwe Leeuwardenweg , are the De Nieuwe Noorder cemetery (formerly the Noorderbegraafplaats ) and the residential areas of Jeugdland (construction 1995-1998) and Elzenhagen-Noord (construction since 2006) and sports park Elzenhagen. The largest part of the polder is located in the southeast. Here is the Buikslotermeer district, along with the Buikslotermeerplein and

420-595: The size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large. Many Russian dachas are 6 ares in size (in Russian, шесть соток ). The decare or dekare ( / ˈ d ɛ k ɑːr , - ɛər / ) is derived from deca and are , and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as

441-477: The southern ring dike ( Buikslotermeerdijk ) disappeared without a trace, as did the older large farmsteads 'Boerelust', 'Herteveld' and 'Elsenhage' (located at the current sports park 'Elzenhagen'). The polder still drains into the drainage system via the Noordhollands Kanaal. The water level in the canal is -1.54 m NAP ( Dutch: Normaal Amsterdams Peil/ English: Amsterdam Ordnance Datum ). In
