State geological survey
State geological survey
The Czech Geological Survey (CGS) is a state-funded organization established by the Ministry of the Environment (MoE) to provide the state geological service for the Czech Republic according to section 17 of Act No. 62/1988 Coll., on geological work (Geological Act), as amended.
The state geological service involves the collection, processing, storage and provision of data on the geological composition of the Czech Republic’s territory, on the protection and use of natural mineral resources and groundwater resources, and on geohazards. These activities are conducted based on specific legislative provisions such as individual agendas, specified further in this section. All activities are listed in the organisation‘s founding charter.
The CGS has long emphasized the use of modern technologies to collect, process and provide data. Access to the outputs of the state geological service and other expert activities are provided mainly via web services and applications. The range of web services and their topics are given in the Maps and data section.

How deep is the deepest borehole in the Czech Republic?
The Jablůnka 1 borehole from 1982 is 6,506 m deep! Temperatures exceeding 160°C were measured in the borehole at a depth of around 5,900 metres and crystalline rocks (Brunovistulicum) were found at its bottom. Additional information on the borehole can be found in the CGS Archive in assessment report P042424. The entire borehole profile is included in the Geologically Documented Objects Database (GDO), and the borehole‘s basic data is recorded in the Borehole Surveys map application.
How many geological project registration forms does the CGS record annually?
Each year, the CGS files more than 5,000 registration forms of geological projects planned in the Czech Republic. The most frequent are engineering-geological and hydrogeological surveys. The Inventory of Geological Projects web page provides detailed information on this agenda.
