Current status of the Geological Base Map
As of 1 September 2018, 41 Estonian Base Map sheets have been entirely or partially covered with the digital Geological Base Map. Altogether 287 thematic maps have been compiled. The database of the Geological Base Map includes some geophysical (aeromagnetic anomalies), geomorphological (erratic boulders), bedrock (stratotypes) and borehole data from the whole country. It also includes digital data obtained during the SedGOF mapping project in the Finnish Gulf (1:200 000 bedrock geology, Quaternary deposits, geomorphology, mineral resources, see figure).
