  • This database contains key information on areas where underground mining or mineral exploration was undertaken in the past. It provides warnings about areas where subsidence or other hazards may occur due to the presence of underground spaces.

  • ArcGIS Server service provides statistical data of radon hazard for Czech's administrative units.

  • ArcGIS Server service provides the results of radon index mapping in the Czech Republic in measure of 1 : 50,000.

  • Spatial layer provides data about the Protected territories for special intervention into the Earth’s crust. It includes (according to §34 of Act 44/1988 Coll.) underground storages, underground depository of radioactive and other waste and industrial use of the Geothermal energy.

  • CGS map server application allows statistical data of radon hazard for Czech's administrative units. Data was processed by CGS and State Office for Nuclear Safety under the Czech Republic Radon Program. Application operates with the Geological map 1 : 50,000 and 1 : 500,000. It's possible to generate komplex radon information in PDF format for municipality centroids.

  • In the database of the "Radon Risk Association“ the measurements of radon in bedrock from the whole area of the Czech Republic are stored. Maps of radon index at a scale of 1:50,000 have 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 using colours to indicate the prevailing radon index for bedrock and quaternary sediments (low, medium, high index).

  • INSPIRE Download Service (ATOM feed) provides access to the results of the mapping of radon index map in the Czech Republic at a scale of 1:50,000.

  • The Mineral information system (SurIS) collects and provides various comprehensive data on the mineral potential of the Czech Republic. It contains the following databases: Mineral deposits and resources Mining leases Database of previous mining lease approvals Protected areas of mineral deposits Exploration areas Spatial features Administrative database

  • SDE database of Slope instability register contains basic data of registered and authenticated slope instabilities (landslides, solifluction, rock falls, etc.). Landslides are classified as active, suspended and stabilized. Database is based on verified mapping in 1 : 10,000 and landslide description and photodocumentation. Data actuality, professionality and its processing is maintained by experts from CGS.

  • 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.
