The map application shows the Czech Republic‘s geothermal potential and its limitations. Map layers indicating the temperature distribution (°C) at various depths ranging from 400 m to 5000 m, a map of heat flux distribution (mW.m-2) at the surface, and a map of the thermal conductivity of rocks (W. m-1. K-1) illustrate the geothermal potential. The application also includes thematic layers depicting limitations and conflicts of interest, which are constraints on the use of geothermal energy due to natural hazards (e.g. floodplains, areas with unstable bedrock and prone to landslides), technical constraints on the construction of geothermal installations (existing infrastructure, mining, etc.), and legislative restrictions (protection of nature and water, etc.).
Maps of the geothermal potential were compiled based on geothermal measurements in 362 deep boreholes in the Czech Republic and adjacent areas, on knowledge of the depth and spatial extent of sedimentary basins, and on the territory‘s geological structure. Due to the uneven distribution of boreholes in the territory, the geothermal maps are more accurate near boreholes, with geological uncertainty increasing with distance. Therefore, the map also depicts a layer of boreholes that were used to create the geothermal maps.
