Sažetak
In making the article, several thematic maps with scale 1:25000 were used. It is the lithological map with outlined engineering geological units, the inclination map with four categories and the landslide map with the areas with increased erosion and generally unstable areas are shown, structural-geomorphological map, surface and groundwater condition map and hydrogeological map. The last one was used with the aim to evaluate the influence of hydrogeological relationship on the synthetic hazard map. The integration of facts from all the maps and engineering evaluation lead to new quality that was presented in the last - synthetic, qualitative map of prognostic meaning. They have been adopted as the factor maps and with their overlapping the map with new contents was made. The Preliminary qualitative map of sliding hazard, including the erosion, was made by heuristic approach, as a predecessor to the hazard map. Such maps proved to be very useful as bases for spatial and development planning on the regional level as well as for evaluation of the site suitability for building.
