Actueel Hoogtebestand Nederland (AHN) is a multi-year program and a collaboration between the water boards, provinces, and Rijkswaterstaat, with the aim of producing a digital elevation model of the Netherlands. This digital elevation model of the Netherlands contains detailed and precise elevation data with at least 10 lidar-derived elevation measurements per square meter. OpenTopography is providing access to version 4 of the AHN DEM which was created from data collected in 2020, 2021, and 2022.
