The data is based on the National Land Survey’s elevation model (rescue map magazines 19M, 19N, 20M and 20N), which has been extracted from the Finnish National Land Survey of Finland. The original model is calculated from the height curves of the baseline map and the coastline elements by triangular network interpolation as a grid model with a screen size of 25 m x 25 m.
