As DTM CRS3035RES50000mN2800000E4800000 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高度网格隶属于“数字地形高程模型（Digital Terrain Elevation Model，DGM）”产品大类。该数字地形高程模型（DGM）以1米间距的规则网格点形式表征地球表面（自然裸土，不含植被），并基于欧洲参考系统完成位置与高程的地理配准。ALS DTM高程网格通过机载激光扫描技术采集获取，是奥地利联邦与各州空间数据提供商联合开发的合作产品。本数据集为总计55幅分幅数据之一，该系列分幅共同覆盖奥地利全境。
