The information on the availability of near-residential public green spaces was ascertained with the aid of a GIS-based procedure of the Senate Department for the Environment, Transport and Climate Protection, under which the following digitally available basic information is used and processed as described below:
- Population Density (Environmental Atlas 06.06, 2018)
- Traffic Volumes (Environmental Atlas 07.01, 2014)
- Inventory of Green and Open Spaces (Environmental Atlas 06.02, 2015)
- Urban Structure / Urban Structure – Area Types Differentiated (Environmental Atlas 06.07 / 06.08, 2015)
- Green-Space Information System (GRIS), (WFS) retrieved on October 12, 2020
- Kompensationsflächenkataster aus Kompensationsinformationssystem (KIS) [Cadastre of compensation areas from the compensation information system], as of 2020
- LOR (lebensweltlich orientierte Räume, Bezirksregionen und Planungsräume) [LEA, living environment areas, boroughs and planning areas, only in German], as of 2019.
The basis for the analysis of the stock of green space is provided by the entirety of green spaces in the area of the city with recreational qualities. Information on size and location of each green space is taken from the Green-Space Information System -as of December 31, 2019 (retrieved on October 12, 2020), as well as the cadastre of compensation areas. The number of inhabitants (as of December 31, 2018) of the blocks and block segment areas (Environmental Atlas Map Population Density 06.06, 2018) were used in order to be able to ascertain the availability of green space for the city’s population.
The information on the respective building structure types of the residential blocks is based on the Map Urban Structure (06.07, 2015) and Urban Structure – Area Types Differentiated (06.08, 2015).
For further data analysis, the living environment areas, boroughs and planning areas (as of 2019) are used as spatial units.
