As DTM CRS3035RES50000mN2700000E4650000 Height grid 1 m Date 15.9.2021

The ALS DTM elevation grid belongs to the product group “Digital terrain height model” (DGM). The digital terrain height model (DGM) describes the earth’s surface (natural soil, without vegetation) in the form of point quantities arranged in a regular grid of 1 m and georeferenced in the European reference systems. The ALS DTM height grid was recorded with Airborne laser scanning technologies. The ALS DTM Höhenraster is a cooperation product of the Austrian official geodata providers of the federal and state governments. This is one of a total of 55 tiles, which together cover the territory of Austria.机载激光扫描数字地形模型（Airborne Laser Scanning DTM, ALS DTM）高程栅格属于“数字地形高程模型（Digital Terrain Height Model, DGM）”产品组。该数字地形高程模型（DGM）以1米为间隔的规则格网点位数据集形式表征地球表面（自然裸土，不含植被），并基于欧洲参考坐标系完成地理配准。本ALS DTM高程栅格通过机载激光扫描技术采集，为奥地利联邦及各州官方地理数据提供商联合产出的合作产品。本数据集为总计55幅分幅数据之一，所有分幅数据共同覆盖奥地利全境。
