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.

The dataset incorporates the main features of the bedrock geology in Norway. Areas of bedrock are classified according to rock type and age. Dyke swarms, tectonic structures, impact sites, and basalts are also shown. The areas of bedrock are also assigned to tectonic units. The map has been compiled using data acquired during several mapping campaigns carried out over decades and therefore the level of accuracy is variable.

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.

The Geological Survey of Norway (NGU) and Norwegian Radiation Protection Authority (NRPA) launched the Radon Susceptibilities Map series in 2006. These maps provide local authorities with important information on the spatial distribution of potential radon hazards, and can be used for determining the priorities for radon measurements in existing dwellings and for evaluating the risks from radon involved in development of new areas. The sources for the radon susceptibility web service are 4 printed maps of the Oslo region at a scale of 1:100 000 available on the NGU website (www.ngu.no).

NGU Geohazards - Rockfall susceptibility in Norway, online. The Rockfall susceptibility dataset shows the potential source areas/trigger areas and runout areas of potential rockfalls. Trigger area - area where the rockfall may occur. Runout area - area which is affected by a rockfall when a rockfall occurs.
