Map viewer Bedrock 1:1 million

Section of a map from the map viewer Berggrund. Illustration.

The map viewer "Bedrock 1:1 million" gives an overview of Sweden's bedrock. The information can be used as a basis for very general planning, analysis, research and education. The map image is adapted for presentation at a scale of 1:1 million, which means that the information is generalized and not intended for more detailed use.
