As DTM CRS3035RES50000mN2650000E4500000 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.ALS DTM高程网格属于"数字地形高度模型（Digital Terrain Height Model，DGM）"产品类别。该数字地形高度模型以1米间隔的规则格网点位数据形式，表征地球表面（自然裸露土壤，不含植被覆盖）的形态，并采用欧洲参考坐标系完成地理配准。该ALS DTM高程栅格（ALS DTM Höhenraster）通过机载激光扫描技术采集获取，是奥地利联邦与各州官方地理数据提供商的合作产品。 本数据集为总计55幅瓦片之一，所有瓦片共同覆盖奥地利全境。
