Abstract: Mountains in Poland (with height over 500 m a.s.l.) cover only 3,1% of the total country area so avalanches are a less serious problem than in e.g. alpine regions. This does not make it less important. Each year in Polish mountains sees a few fatal accidents caused by avalanches. The greatest tragedy took place on the 28th of March, 1968, when the avalanche in the Karkonosze Mountains area killed nineteen people. GIS technology is widely used for research on snow avalanches, mainly for creating avalanche risk and hazard maps. This technology was also used for mountainous areas in Poland. First GIS analyses in Poland were created in 2004 for selected parts of the Tatra Mountains. The results seem to be satisfying so these activities become increasingly popular in other regions. The main goal of this study is to compare different types of Digital Elevation Models (DEM), especially with high resolution DEM generated from Light Detection and Ranging (LiDAR) - Airborne Laser Scanning (ALS) data, in the context of estimating potential avalanche release areas and future dynamic calculations in small mountain regions. Study shows how different digital data may influence predictions’ results and procedures. Test sites in the Karkonosze Mountains, Sudety and the Tatra Mountains in Carpathian were chosen for this study.
