As DTM CRS3035RES50000mN2700000E4550000 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. Reference date = creation date: The data for this day are the most up-to-date database of the BEV. This is not identical with the recording or survey date. The topicality can be found in the corresponding series under “Downloads, Views and Links” in the update overview.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。数字地形高程模型（DGM）以1米间距的规则格网点形式描述地球表面（自然地表，不含植被），并在欧洲参考系统中完成位置与高程的地理配准。该ALS DTM高程网格采用机载激光扫描（Airborne Laser Scanning）技术采集获取。ALS DTM高程网格是奥地利联邦与州级空间数据提供商的合作成果。本次数据集为总计55幅瓦片之一，所有瓦片共同覆盖奥地利全境。参考日期=创建日期：当日数据为奥地利联邦测绘局（BEV）的最新数据库。该参考日期并不等同于数据采集或勘测日期。可在更新概览中的“Downloads, Views and Links”栏目下的对应系列中，查阅该数据集的现势性信息。
