The task of the Czech Geological Survey, established in 1919, is to provide the state geological service for the Czech Republic. Although the character of the institution, together with its name, has changed over time, its main mission and related unique social status have remained. The Czech Geological Survey has the statutory responsibility to gather, store and interpret geological information so that the state administration can take appropriate decisions about national economic and environmental issues. It provides the results of systematic regional geological mapping and investigation to all interested persons.
