As DTM CRS3035RES50000mN2700000E4800000 elevation grid 1 m cut-off date 15.9.2019

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）数字地形模型（Digital Terrain Model，DTM）高度网格，隶属于「数字地形高程模型（Digital terrain elevation model，DGM）」产品类别。数字地形高程模型（DGM）以1米间隔的规则网格点形式表征地球自然裸土表面（无植被覆盖），并采用欧洲参考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采集生成，为奥地利联邦与各州空间数据提供商的合作研发成果。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。
