The Bouguer anomaly is defined as the difference between the gravity measured at a specific point on the Earth’s surface and a gravity value calculated at the same point assuming that the Earth’s crust is homogeneous. This map shows both the regional negative anomalies associated with the Alps and the positive anomaly of the Sesia–Finero zone that signifies an excess of mass at depth.

Database contains data from gamma-spectrometry survey. Gamma-ray spectrometry survey means measurement of natural radioactive isotopes concentration i.e. potassium 40K [%], uranium 328U and 235U [ppm], thorium 232Th [ppm]; simultaneously, total gamma-ray activity was registered. This survey started in 1976 and covered about 60 % of the territory.

This database contains reports and assessments including geophysical measurements made since the 1950s. It also contains research studies and projects carried out in the Czech Republic and abroad. Access to the archive is provided by the Geophysical Archive Unit, located at the CGS office in Brno.

WMS service displays the Radiometric field map of the Czech Republic 1:500,000 (M. Manová, M. Matolín, 1995). This map was published by the Czech Geological Survey in the Atlas of map of the Czech Republic (GEOCR500) in 1998. Data on the gamma dose rate of rocks are based on regional and detailed airborne measurement of terrestrial radiation. The data of the map illustrate the regional distribution of natural radionuclides in rocks in the Czech Republic.

WMS service shows the localization of Vertical electrical sounding (VES) measuring points of selected campaigns, registered in the Czech Republic since 1957.

The database (ORACLE) contains magnetic anomalies delta ?T that has been measured by airborne magnetometry survey at scale 1:25,000 since 1960 (about 85 % of the whole territory); the rest is covered by measurement at scale 1:200,000 (1958-1960). The period 1960-1971 is represented by analogue recording (flux-gate magnetometer) with accuracy ca 10 nT. The next measuremets have been carried out using digital registration (proton or cesium magnetometer) with accuracy ca 2 nT. The results of ground magnetometry is added to the airborne magnetometry data in region of Eastern Moravia, Krkonoše Mountains and Šumava Mountains, where no airborne data was registered.

This database contains state-paid seismic profiles measured in the Czech Republic. The layer has been transformed according to the INSPIRE data specification for the Geoph Profile object from the Geophysics application scheme.

This database contains data from radiometric survey. Radiometry means the measurement of the total gamma-ray activity of natural radioactive isotopes on the Earth’s surface, in the past the total exposure rate was measured. The first stage (measurement of exposure rate) was carried out in 1957-1973 using Geiger-Mueller counter; this survey covered the whole territory of the Czech Republic, measured data is stored in [µR/h]. Next stage started in 1976 when total gamma-ray activity was registered simultaneously with gamma-ray spectrometry survey and covers about 60 % of the territory, measured data was stored as total gamma-ray activity [Ur].

This database contains the locations of points at which vertical electrical profiles and sounding curves were measured. The database of VES measurements (vertical electrical sounding) was established in 1994. The layer has been transformed according to the INSPIRE data specification for the Geoph Station object from the Geophysics application scheme.

The database contains information on two dozen geophysical networks operated by czech geoscience institutions of the CzechGeo consortium (institutes of the ASCR, faculties of universities, etc.) in the Czech Republic and abroad. There are observatories, permanent stations and measuring points of campaigns (seismic, GPS, magnetic, gravimetric and geodynamic), connected to local and global data networks.
