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.

ArcGIS Server service displays state-funded seismic profiles measured in the Czech Republic in 1971-1994.

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.

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.

This database contains the locations of points at which vertical electrical soundings were measured.

Gravimetric map (J. Sedlák, Geofyzika, a.s., 1998) was published in Atlas of maps of the Czech Republic GEOČR500 in 1998 by CGS. It contains a raster image of gravimetric field. Map was created on the basis of measurements of 283 718 detailed points of gravity.

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