Current Height file Netherlands (AHN) DTM
Description
The Actueel Hoogtebestand Nederland DTM (AHN) is the digital height map for the entire Netherlands of the ground level without the objects such as buildings or trees. The AHN raster 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 an aircraft scans the earth's surface with a laser beam. The measured heights (points) are 3D point clouds and grids. AHN is a collaboration between the provinces, the national government and the water boards. The height file AHN4 DTM ground level grid is the grid that is manufactured by classifying points as "ground level" and converting them to a grid based on a Squared IDW method. No further edits have been performed. Items that have been omitted are objects such as trees, buildings, bridges, water and other objects. The current AHN is version 4, this version has been collected over the years 2020, 2021 and 2022. For more information on the AHN see https://ahn.nl/ahn-4.
