Slope classes over 30 degrees

Derivate representation of the digital terrain model swissALTI3D and models from France, Italy, Austria and Germany, which allows for the identification of inclinations over 30°. According to the recommendation of the Institute for Snow and Avalanche Research SLF the slopes are categorized into 4 classes. They were calculated from a combined digital terrain with a resolution of 10m made up from swissALTI3D for Switzerland and Liechtenstein, RGE ALTI for France, TINITALY for Italy, DGM10 for Austria, DGM1 for Bavaria and Baden-Württemberg. The precision of the inclination values in the transistional area between the different base models cannot be guaranteed. Liability claims for the representation of gradients over 30° cannot be asserted.
