Urban green areas and indicators: Heidelberg

The data set contains all publicly accessible green spaces of the city of Heidelberg including an attribute table with 38 different indicators. The green spaces and indicator values are the central data base for the assessment of green areas according to criteria or suitability for certain activities using the my Grün-App (app.meingruen.org). The green space polygons were generated using an automatic approach, which was developed in Ludwig et al. (2021) is described in more detail. The formation is based on assumptions about physical barriers, in particular the road, rail, and water networks, as well as limits of certain neighbouring land use class combinations. For Heidelberg, the green space polygons were formed by a combined processing of OpenStreetmap and urban data, especially a geometry for statistical blocks, parks and green areas, playgrounds, cemeteries, small gardens and forests. Indicators were processed by the Leibniz Institute for Ecological Spatial Development, the Heidelberg Institute for Geoinformation Technology at Heidelberg University and the Institute of Cartography at TU Dresden. The data bases and calculation rules used for the calculation of the indicators are documented in the metadata description. # References: Cakir, S.; Hecht, R.; Krellenberg, K.
