In the framework of an Interreg IVa project LIDAR datasets have been recorded in the Austrian-Bavarian border region (Salzburg, Tyrol, and Berchtesgaden). The pre-processed LIDAR data result in Digital Surface Models (DSM) and Digital Terrain Models (DTM) from which vegetation heights as normalized canopy height model (nCHM) have been extracted by using Object Based Image Analysis (OBIA) techniques.
The objective is to calculate vegetation based shadow areas for different time periods. This will be an input parameter for the evaluation of existing and planned alpine skiing slopes. In cooperation with the Centre for Meteorology and Geodynamics (ZAMG) a Snow Height Index (SHI) will be developed and spatially explicit represented for past, present and future snow heights at different years and times.
