The AHN DEM is a 0.5m DEM covering the Netherlands. It was generated from LIDAR data taken in the spring between 2007 and 2012.
It contains ground level samples with all other items above ground (such as buildings, bridges, trees etc.) removed. This version is non-interpolated; the areas where objects have been removed are left blank and not filled with interpolated values. The point cloud was converted to a 0.5m grid using a squared inverse distance weighting method.
