收藏资源简介:
The ALS DTM elevation grid belongs to the product group “Digital terrain height model” (DGM). The digital terrain height model (DGM) describes the earth’s surface (natural soil, without vegetation) in the form of point quantities arranged in a regular grid of 1 m and georeferenced in the European reference systems. The ALS DTM height grid was recorded with Airborne laser scanning technologies. The ALS DTM Höhenraster is a cooperation product of the Austrian official geodata providers of the federal and state governments. This is one of a total of 55 tiles, which together cover the territory of Austria.
ALS DTM高程网格隶属于“数字地形高程模型(Digital Terrain Height Model, DGM)”产品组。数字地形高程模型(DGM)以1米规则网格排布的点位数据形式刻画地球表面(自然土壤层,不含植被覆盖),并采用欧洲参考坐标系完成地理配准。该ALS DTM高程网格通过机载激光扫描(Airborne Laser Scanning)技术采集获取。ALS DTM高程栅格为奥地利联邦及各州官方地理数据提供商的合作产出成果。本数据集为总计55个瓦片之一,所有瓦片联合覆盖奥地利全境。
