The information on the availability of near-residential public green facilities was ascertained with the aid of a GIS-based procedure of the Senate Department for Urban Development | E 1, under which the digitally available basic information is used in the calculation process as described below.
The basis for the analysis of the stock of facilities is provided by the entirety of green spaces in the area of the city with recreational potential. Information on size and location of each green space is taken from the Green Space Directory of Section IC of the Senate Department for Urban Development and the Environment, (as of April 2011), which includes all green space data from all the boroughs regarding all public green facilities of the use type “Parks and Green Spaces”.
Since 2006, the daily-life oriented spaces, borough regions and planning areas based on the ISU5 Block Segment Map (current as of 2010) have been used for the ascertainment of logical spatial units. These daily-life oriented spaces have replaced the statistical areas which were previously used.
In order to be able to ascertain the availability of green space for the city’s population, it was necessary to ascertain the number of residents of the city. The number of inhabitants of the blocks was obtained from the residents’ file of the Environmental Atlas 06.06, 2012 edition, current as of 2011.
The information on the respective building structure types of the residential blocks is based on Map 06.07 Urban Structure, of the Environmental Atlas (2011 Edition; information current as of 2010).
