Current Height file Netherlands (AHN) DSM
Description
The Current Height File Netherlands DSM (AHN4) is the digital height map for the whole of the Netherlands including all objects on site. The grid files have a resolution of 0.5 meters. 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 a plane with a laser beam scans the Earth’s surface. Of the measured heights (points), 3D point clouds and grids are made. Ahn is a collaboration of the provinces, government and water boards. The AHN4 DSM altitude is the grid made from all points except those classified as “water” based on a Squared IDW method. No further operations have been carried out.
It also contains trees, buildings, bridges and other objects.
The current AHN is version 4, this version has been obtained over the years 2020, 2021 and 202.
