  • The Superficial Deposits of Norway (best of) is a database giving full coverage of the superficial deposits throughout Norway. High resolution data at scales of 1:20 000 to 1:50 000 exists for only about 30% of the country, mostly in areas where superficial deposits are of significant economic importance. The deposits are classified according to their genesis and thickness. For most of the data collated at a scale greater than 1:250 000 derived information such as groundwater potential and infiltration capacity have been added as attributes.

  • Map showing Trigger areas - areas where a rockfall may occur, and Runout areas - areas that are affected by a rockfall when a rocfall occurs. The maps have been compiled using a computer model that recognizes the possible source areas/trigger areas in which a rockfall could occur. The criteria used for recognition are the slope of the mountain side and relevant geological information. For each source area/trigger area the runout area of the potential rockfall is calculated automatically using a DEM in combination with the relevant geological information. No field survey has been carried out for the preparation of these maps.
