As DTM CRS3035RES50000mN2700000E4350000 elevation grid 1 m cut-off date 15.9.2021

The ALS DTM height grid belongs to the product group “Digital terrain elevation model” (DGM). The digital terrain elevation model (DGM) describes the earth’s surface (natural soil, without vegetation) in the form of dots arranged in a regular grid of 1 m and georeferenced in position and height in the European reference systems. The ALS DTM elevation grid was recorded with Airborne laser scanning technologies. The ALS DTM Height Grid is a cooperation product of the Austrian federal and state spatial data providers.This is one of a total of 55 tiles, which together cover the territory of Austria.ALS DTM高度栅格隶属于“数字地形高程模型（Digital Terrain Elevation Model，DGM）”产品类别。数字地形高程模型（DGM）以1米间距的规则格网点形式表征地球表面（自然裸土，不含植被），并采用欧洲参考系完成位置与高程的地理配准。该ALS DTM高度栅格采用机载激光扫描（Airborne Laser Scanning，ALS）技术采集，是奥地利联邦与州级空间数据提供商的合作成果。本次提供的数据为总计55幅栅格瓦片之一，该组瓦片共同覆盖奥地利全境。
