Stadtgrünraster Deutschland 2018

The data acquisition comprises two main processing steps: (1) Collection, processing, and automated classification of the multispectral Sentinel 2 satellite data with the “Land Cover DE method”, resulting in the raw land cover classification dataset, NDVI layer, and RF assignment frequency vector raster. (2) GIS-based postprocessing including discrimination of (densely) built-up and loosely built-up pixels according NDVI threshold, and creating water-body and arable-land masks from geo-topographical base-data (ATKIS Basic DLM) and reclassification of water and arable land pixels based on the assignment frequency Satellite data were searched and downloaded from the Copernicus Open Access Hub (https://scihub.copernicus.eu/). The LUCAS reference and validation points were loaded from the Eurostat platform (https://ec.europa.eu/eurostat/web/lucas/data/database). The processing of the satellite data was performed at the DLR data center in Oberpfaffenhofen. GIS-based post-processing of the automatic classification result was performed at IOER in Dresden.
