Description: In the early 1970's the Geological Survey began regional gravity surveys in which station density has varied from 1 to 8 per square km. The data covers about 30 % of Finland's land area. Data is suitable especially for ore exploration and bedrock mapping. The downloadable product contains only the index of measurement stations (coordinates and dates). The purchasable data (absolute gravity values, Bouguer anomalies etc.) inquiries at geodata@gtk.fi.
