As DTM CRS3035RES50000mN2700000E4500000 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"数字地表高程模型（Digital Terrain Elevation Model, DGM）"产品组。数字地表高程模型（DGM）以1米间距的规则格网点位形式表征地球表层（自然土壤，不含植被），并在欧洲参考坐标系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，是奥地利联邦与各州空间数据提供商的合作成果。 该数据集为总计55幅分幅之一，所有分幅共同覆盖奥地利全境。 参考日期 = 制作日期： 此日期对应的数据为BEV的最新数据库资料。该日期与数据采集或外业测量日期并不一致。数据的时效性详情可在更新概览中"下载、浏览与链接"对应的系列条目下查询。
