Borehole surveys of the Czech Republic – INSPIRE harmonized (theme Geology)
This database contains key information on boreholes. The database is generated about twice a year as a layer in a GIS environment for use in the Borehole Surveys application. Individual points in the application represent boreholes and polygons indicate groups of related boreholes.
Compilation of the database was initiated in the mid-1970s under the name "Register of boreholes of the factographic geological databank". It was greatly enlarged during the 1980s when data from tens of thousands of boreholes were entered into the register every year. In 1990, intensive loading of archival borehole data was completed. The annual acquisition, mostly of records from newly-drilled boreholes, now ranges between 4 and 5 thousand.
