AHN DEM은 네덜란드를 포함하는 0.5m DEM입니다. 2007년에서 2012년 사이 봄에 촬영된 LiDAR 데이터에서 생성되었습니다.
지상 위의 다른 모든 항목 (예: 건물, 다리, 나무 등)이 삭제된 지상 수준 샘플이 포함되어 있습니다. 이 버전은 보간되지 않습니다. 객체가 삭제된 영역은 비워져 있으며 보간된 값으로 채워지지 않습니다. 포인트 클라우드는 제곱 역거리 가중치 방법을 사용하여 0.5m 그리드로 변환되었습니다.

It was generated from\nLIDAR data taken in the spring between 2007 and 2012.\n\nIt contains ground level samples with all other items above ground (such as\nbuildings, bridges, trees etc.) removed. This version is non-interpolated; the\nareas where objects have been removed are left blank and not filled with\ninterpolated values. The point cloud was converted to a 0.5m grid using a\nsquared 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.
