Height DTM 50
Digital terrain model with heights in a 50 x 50-metre grid. Created primarily on the basis of height information from N50. The height themes are: elevations, peaks, trig points, coast, lakes, roads. Created as 100 x 100 km tiles. The names of the tiles reflect the UTM coordinates in the bottom left-hand corner, two digits for the north coordinate and two digits for the east coordinate. The standard deviation of elevation is +/- 4-6 metres. The data covers mainland Norway and islands. The model continues some way on the foreign side to the east with data of uncertain quality. This dataset was produced in 2007. There are no plans to update this dataset.
