The dataset contains all publicly accessible green spaces in the city of Heidelberg, including a rating for suitability for physical and passive activities. The attribute table contains scores that express the suitability of the green spaces in relation to the implementation of 20 different activities. The scores are the result of a multi-criteria evaluation, which is published in Cakir et al. (2021). The following inputs were taken into account in the calculation: - normalized indicator values of the criteria (see https://doi.org/10.26084/IOERFDZ-DATA-DE-2021-2) - the weighting defined by the users (see standard weights from 0 to 10 in Table 1) of the criteria. The green space polygons were generated using an automatic approach described in Ludwig et al. (2021) is described in more detail. The formation is based on assumptions about physical barriers, specifically the road, rail and water network and boundaries of certain adjacent land use class combinations. For Heidelberg, the green area polygons were formed by a combined processing of OpenStreetmap and urban data, especially a geometry for statistical blocks, the parks and green areas, playgrounds, cemeteries, allotments and forests. # References: Cakir, S.; Hecht, R.; Krellenberg, K.
