Abstract
The landslide risk mapping procedure using GIS technology was developed in the co-operation of scientists at the Institute of Geonics, Czech Academy of Sciences, Ostrava and Technical University of Ostrava, Czech Republic. The procedure is based on the application of standard data available in the public databases in a raster form, the vector form of data is accessible for the disaster management staff only. The risk assessment respects relevant territory features, as slope, aspect, geology, soil humidity, drainage network, land use, registered landslides. All the features were assessed using 0-3 mark scale. The summarization of individual feature assessment provides the final level of the landslide risk in the area. The final resolution of mapping outputs is decimetres. The risky areas were highlighted in the 100 m wide buffer zones along the built objects and technical infrastructure. The maximum landslide risk map data overlay with topic radar data on running and antecedent precipitation shows endangered areas. The risk map combination with a cadastral map selects namely endangered administrative units. The resolution of the landslide risk map allows local administration to organize risk areas monitoring to prevent human casualties and to deploy measures to reduce material damages.
