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.).
fullfillment of requirements of the INSPIRE directive
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.

Open dataset contains basic data on Slope deformations (landslides, solifluction, rock falls, etc.) within the territory of the Czech Republic. Landslides are classified as active, suspended and stabilized. Database is based on verified mapping in 1 : 10,000 and landslide description and photodocumentation. The current form of the data corresponds to the revised methodology for monitoring slope deformations (formerly slope instabilities) from 2021.
The purpose is to inventory the area with detected slope deformations in accordance with the provisions of § 17 of the Geological Act (No. 62/1988 Coll., on geological works, as amended). These areas can have an impact on the development of spatial planning documentation and on the environment. ČGS provides data on slope deformations to public authorities and spatial planning authorities for the processing of spatial analytical documents in accordance with the valid Building Act.
