Description
The Actueel Hoogtebestand Nederland (AHN) is a dataset with detailed and precise elevation data for the whole of the Netherlands. Elevation information was collected from helicopters and aircraft using laser technology with vertical accuracy of 5 cm.
AHN3 Dataset contains the Netherlands AHN 0.5m DSM and DTM variables. The data cover the period between 2014 and 2019.
The Digital Terrain Model (DTM) product represents the elevation of the ground, while the Digital Surface Model (DSM) product represents the elevation of the tallest surfaces at that point.
