AHN DEM, Hollanda'yı kapsayan 0,5 m'lik bir DEM'dir. 2007 ile 2012 yılları arasında ilkbaharda alınan LIDAR verilerinden oluşturulmuştur.
Bu sürüm hem yer seviyesindeki örnekleri hem de yer seviyesinin üzerindeki öğeleri (binalar, köprüler, ağaçlar vb.) içerir. Nokta bulutu, kareli ters mesafe ağırlıklandırma yöntemi kullanılarak 0,5 m'lik bir ızgaraya dönüştürüldü.

The point cloud was converted to a\n0.5m grid using a squared inverse distance weighting method.\n\n### Bands\n\n\n**Pixel Size**\n\n0.5 meters\n\n**Bands**\n\n| Name | Units | Pixel Size | Description |\n|-------------|-------|------------|-------------|\n| `elevation` | m | meters | Elevation |\n\n### Terms of Use\n\n**Terms of Use**\n\nThe datasets of the AHN are available as Open Data.\nThis means that the data can be used by anyone for free and without\nrestrictions.
