Open dataset contains key information on areas in the Czech Republic, where underground mining or mineral exploration were undertaken in the past. The mine workings are irregularly distributed within the vector representation and at different depths. Polygons can also contain completely unmined sections. The possible damage to the terrain by mining activities is usually smaller than the extent of the vector representation.
The purpose is to inventory areas with detected undermining according to the Geological Act (No. 62/1988 Coll., on geological works, as amended). These areas can have an impact on the development of urban planning documentation and on the environment. CGS provides data on undermined areas to public authorities and spatial planning authorities in accordance with the valid Building Act. Furthermore, this data is used in the assessment of mine workings impacts and the processing of complex information about the territory.
Landslides dataset generated as the INSPIRE layer from the Slope Deformations Register, which contains basic data of registered and verified slope deformations in the Czech Republic (landslides, solifluction, rock falls, etc.).

Radon index map of the Czech Republic 1 : 50,000 has been compiled using statistical procedures to process the measurements so that the areas defined by the vectorized boundaries of the geological units can be classified to indicate the prevailing radon index for bedrock and quaternary sediments (low, medium, high index). The source data has been adjusted to meet the INSPIRE requirements for download service.
