Current Height file Netherlands 1 (AHN1) DTM

The Current Height File Netherlands (AHN) is the digital height map for the whole of the Netherlands. Ahn is a collaboration of the provinces, government and water boards. The height is measured with laser altimetry: a technique in which a plane with a laser beam scans the Earth’s surface. The AHN1 was collected in the period 1996-2002.For more information on the AHN see https://ahn.nl.

In this WMS, the AHN1 grid files with a resolution of 5 meters are included. The DTM is intended as a ground level file, where all points classified as “moving ground” have been re-sampled to a grid based on a Squared IDW method.
