Open-Space Development 2010
The Environmental Atlas Map 06.03 Open-Space Development since 1950, dated 1985 and used as the major source, shows open-space losses for West Berlin for the periods 1950-1970, 1970-1980 and 1980-1984, and open space gains based on the open space existing in 1984 (scale: 1:50,000). The city atlases used, the 1950 and 1970 editions of Berlin in der Tasche (Berlin in your pocket), scale 1:20,000-25,000, the 1975 Berlin City Atlas, scale 1:8,000, and the 1980 East Berlin atlas Buchplan Berlin Hauptstadt der DDR (Atlas of Berlin, Capital of the GDR), scale 1:25,000, were used to ascertain the open-space stock in 1950, 1970 and 1980 in East Berlin. The open-space stock in both East and West Berlin in 1990 was taken from the Euro-Großraumstadtatlas Berlin 1990 (Euro City Atlas of Greater Berlin), scale: 1:20,000, and the 1991 Berlin city map, scale: 1:25,000/ 35,000.
The Environmental Atlas Maps 06.01 Actual Use of Built-Up Areas and 06.02 Inventory of Green and Open Space, which were drafted parallel to the present map, were consulted for the definition and delimitation of the open-space stock, and for the open-space losses and gains. These maps show the green and open-space stock at black and block segment level. In addition, the infrared aerial images from a fly-over in August 1990 were used to ascertain the open-space stock in 1990. They are available in two different photographic scales: in a scale of 1:4,000 for West Berlin and the areas near the former border, and in a scale of 1:6,000 for the area of East Berlin.
For an ascertainment of the open-space losses and gains for the 1990 to 2000 decade and for the 2000 to 2005 period, the information in the geo-database “Areas with Change Potentials of City-Wide Significance” of the Urban Development Planning and Soil Management Section of the Senate Department for Urban Development was consulted. Based on the assignment issued with the FNP resolution of the Berlin state parliament in 1994 to check the basic conditions regularly, the actual consumption of land is documented here. Areas investigated are those with a minimum potential of 100 housing units, 10,000 sq. m. of gross floor space (BGF) for services, 5,000 sq. m. of retail selling space, 1 hectare of commercial basic space or 3 hectares of green space or woodland. Items described include previous use, planned use, projected and actual completion. In order to show the actual state of land consumption, projects were also taken into account, the realization of which had already begun, but had not yet been concluded.
For the check of changed areas and the ascertainment of the open space stock in 2005, digital orthophotos at a scale of 1:5,000, from an overflight in 2004 (Sect. III), were used.
The update of the 2013 edition was based on Environmental Atlas Maps 06.01 Actual Use of Built-Up Areas and 06.02 Inventory of Green and Open Spaces, Edition 2011, drawing on factual data from 2010.
