ArcGIS Server service contains information on geophysical measurements made mainly by Geofyzika Brno since the early 1950s. Areas covered by regional surveys are depicted on 1:200 000 scale maps and local small-scale measurements at scale of 1:50 000. Service contains also layers of seismic (2D reflection seismic and well shoots), vertical electric sounding (polygons, lines, points) and localization of the geophysical surveys on the territory of the Czech Republic (both regional and local).
