Slope classes over 30 degrees

Description

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.
