As DTM CRS3035RES50000mN2600000E4500000 elevation grid 1 m cut-off date 15.9.2022

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高程网格属于"数字地形高程模型（Digital Terrain Elevation Model, DGM）"产品组。数字地形高程模型（DGM）以1米间距的规则网格点形式表征地球表面（自然土壤层，不含植被），并采用欧洲参考坐标系完成位置与高程的地理配准。该ALS DTM高程网格通过机载激光扫描技术获取。ALS DTM高程网格是奥地利联邦与各州空间数据提供者的合作产品。本数据集为总计55幅瓦片（tiles）之一，所有瓦片共同覆盖奥地利全境。
