Potential accessible coastal zone

Potential accessible coastal zone is calculated based on terrain, roads, railways, cultivated land areas, buildings and coastline. Data are from different sources and processed into land use surfaces by Statistics Norway. The surfaces which are not affected by anthropogenic activity are considered potentially available for outdoor activities. The different surfaces also contain features showing the steepness with following categories: little steepness <3, some steepness 3-10, large steepness 10-25 and very high steepness > 25 degrees. Potential accessible coastal zone are geographical areas with boundaries changing over time depending on anthropogenic activity.
