As DTM CRS3035RES50000mN2650000E4600000 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.机载激光扫描（Airborne Laser Scanning，ALS）DTM高程网格隶属于“数字地形高程模型（Digital Terrain Elevation Model，DGM）”产品组。该数字地形高程模型（DGM）以1米间隔的规则格网点位形式表征地球表面（自然裸土，不含植被），并在欧洲参考坐标系中完成位置与高程的地理配准。此ALS DTM高程网格采用机载激光扫描技术采集获取，为奥地利联邦及各州空间数据提供商的合作产出成果。本数据集为覆盖奥地利全境的总计55幅标准瓦片之一。
