As DTM CRS3035RES50000mN2800000E4500000 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高程网格属于数字地面高程模型（Digital Terrain Elevation Model，DGM）产品组。该数字地面高程模型（DGM）以1米间距的规则格网点位形式表征地球表面（原生土壤层，不含植被覆盖），并采用欧洲参考坐标系实现位置与高程的地理配准。ALS DTM高程网格通过机载激光扫描技术采集获取，是奥地利联邦与各州空间数据提供商联合推出的合作产品。 该数据集为覆盖奥地利全域的总计55幅分幅数据之一。 参考日期=制作日期： 此日期对应的数据集为BEV的最新数据库版本。该参考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对应系列的「下载、查看与链接」板块的更新概览中查询。
