Register of Geographical Names is a basic national spatial layer. It includes geographical names of spatial features, which have some historical, ethnically or social important identity (these features are more or less permanent). The register includes names of populated places, names of hydrography features, names of relief features and names of areas. The sources are topographical maps at a scale of 1 : 5.000 and 1 : 10.000, 1 : 25.000, 1 : 250.000 and 1 : 1.000.000. Register of Geographical Names is a basic spatial layer used for georeferencing of different spatial features, for linking of other spatial layers with geographical names, for different topographical and cartographical applications, for statistical and linguistic analysis.
Geological Units are polygons, defined by equal composition (lithology) and age.
Mineral deposits and resources
Data of Geological map were reclassified into classes of IAH classification on the base of hydrogeological characteristics. IAH classification is based on description of the hydrogeological units. Firstly, based on extensiveness and productivity and secondly on type of porosity. The purpose is to provide assistance to the strategy of groundwater exploitation as to protection and water resources management.
Layer shows discontinuities in the geological structure, and characterizes them according to their type and observation method.
