As DTM CRS3035RES50000mN2800000E4500000 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高程格网（Airborne Laser Scanning Digital Terrain Model Height Grid，ALS DTM Height Grid）隶属于"数字地形高程模型（Digital Terrain Elevation Model，DGM）"产品组。数字地形高程模型（DGM）以1米间距的规则格网点阵形式表征地球表面（原生土壤层，不含植被覆盖），并在欧洲参考坐标系中完成了位置与高程的地理配准。该ALS DTM高程格网通过机载激光扫描技术采集生成。本数据集为奥地利联邦与各州空间数据提供商的合作产出成果。本次提供的格网为覆盖奥地利全境的总计55幅格网瓦片之一。
