  • 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 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].

  • 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.

  • 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.

  • In the database of the "Radon Risk Association“ the measurements of radon in bedrock from the whole area of the Czech Republic are stored. Maps of radon index at a scale of 1:50,000 have been compiled using statistical procedures to process the measurements so that the areas defined by the vectorized boundaries of the geological units can be classified using colours to indicate the prevailing radon index for bedrock and quaternary sediments (low, medium, high index).

  • This database (SDE) contains data from a gravity survey of the entire Czech Republic at the scale of 1:200,000 from the period 1957-1960 (100% of the territory – ca 23 thousand gravity points). Since 1960, the systematic gravity survey at the scale of 1:25,000 has started and covers nearly 70 % of the Czech Republic area. At the end of 2018 the database contains 3,992 gravity points from the old mapping at the scale 1:200,000 and 304,199 points from the detailed mapping 1:25,000; this new data replaces the old one.

  • INSPIRE View Service provides the results of radon index mapping in the Czech Republic in a scale of 1 : 50,000.

  • Magnetic map (K. Šalanský, 1995) of the Czech Republic in a scale 1 : 500,000 (GEOCR500) in the izanomal T (Z) form. Selected basic interval of isolines of 25 n T represents sufficiently accurately the course of the magnetic field. The map si complemented by the list of reports where are noticed basis which were used for the preparation of magnetic maps. The map is complemented by the selection of literature for interpretation of magnetic anomalies.
