Land-use intensity depiction of grasslands in Germany by using optical satellite data (Sentinel-2) and machine learning methods (see Lange et al 2021). Land-use intensity product includes: (1) Livestock density (livestock units per day and ha); (2) Mowing frequency count; (3) Fertilisation (boolean: 0=no, 1=yes); (4) Field usage (1=mown pasture, 2=pasture, 3=fertilized meadow, 4=meadow, 5=others); (5) Land-use intensity index (see Bluethgen et al 2012); (6) Land-use classes derived from ATKIS data (see BKG 2015); References: [Bluethgen 2012]: Bluethgen, N., Dormann, C.F., Prati, D., Klaus, V.H., Kleinebecker, T., Hoelzel, N., Alt, F., Boch, S., Gockel, S., Hemp, A., Mueller, J., Nieschulze, J., Renner, S.C., Schoening, I., Schumacher, U., Socher, S.A., Wells, K., Birkhofer, K., Buscot, F., Oelmann, Y., Rothenwoehrer, C., Scherber, C., Tscharntke, T., Weiner, C.N., Fischer, M., Kalko, E.K.V., Linsenmair, K.E., Schulze, E., Weisser, W.W., 2012.

Quantification of grassland land-use intensity and its components livestock density, number of mowing events and fertiliser application using machine learning algorithms and time series of Copernicus Sentinel-2 optical satellite data with 20 m spatial resolution. Land-use intensity was inferred using the index proposed by [Blüthgen 2012]. Input variables (livestock, mowing and fertilisation) were derived from Sentinel-2 optical satellite data using Convolutional Neural Networks trained on data from the DFG Biodiversity Exploratories. More details will be made available soon in [Lange 2021]. Grassland pixels were chosen according to the digital landscape model (DLM) of the official topographic-cartographic information system ATKIS [BKG 2015]. Livestock densities are livestock units (calculated from animal number, species and age) per ha and day and were aggregated into four livestock classes (see [Lange 2021]). Mowing number represents the number of cuts in the respective year. Fertiliser application is given as boolean, fertilised or not fertilised.
