Current Altitude File Netherlands DSM

The Current Height File Netherlands DSM (AHN4) is the digital height map for the whole of the Netherlands. The AHN raster files have a resolution of 0.5 metres. It contains detailed and precise height data determined with a minimum of 10 height measurements per square meter. The height is measured with laser altimetry: A technique in which an aircraft scans the earth's surface with a laser beam. 3D point clouds and grids were created from the measured heights (points). AHN is a collaboration between the provinces, central government and the water boards. The elevation file AHN4 DSM is the grid constructed from all points except those classified as "water" based on a Squared IDW method. No further edits have been made. It also contains trees, buildings, bridges and other objects. The current AHN is version 4, this version was obtained for the years 2020, 2021 and 202.
