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.
Open dataset contains data on underground mine workings and on reported impacts of mine workings over the territory of the Czech Republic. Attributes include detailed information about each object, e.g. the exact location, topographical situation, proprietary relation, technical data, the current state of these workings, their hazardousness and possible security measures. There are also links to the signatures of source reports stored in the CGS Geofond archive and to the digital documentation in *.jpg format - e.g. photograph, map cut-out, drawing.
Data from the database are continuously used in monitoring the safety of mine workings according to the Mining Act, in land-use planning, and as a part of the urban planning documentation according to the Building Act.
Open dataset contains basic information on all reserved mineral deposits and approved prognosticated mineral resources in the territory of the Czech Republic.The Ministry of the Environment issues a certificate of reserved deposit if a reserved mineral is found in quantity and quality that allow its accumulation to be reasonably expected.
According to Act No. 44/1988 Coll., Mininig Act ( § 6).
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.
