摘要
LiDAR技术可直接获取三维地表地形数据,具有传统摄影测量方法和地面常规测量技术无法比拟的优越性,已成为获取高时空分辨率地球空间信息的一种全新技术手段,引起了国内外学者的极大关注。LiDAR技术在地形测绘、环境监测、三维城市建模等诸多领域具有广阔的发展前景和应用需求。文中采用试验数据,检测并评价Li-DAR系统生成的DEM、DOM精度,探讨其在基础测绘中的应用可能性,具有现实意义。
LiDAR has the advantage of acquiring 3d terrain data directly, which is superior to most of traditional measurements. LiDAR provides a new technology for obtaining high special resolving power data, and it attracts the attention of scholars at home and abroad. It is widely used in many areas, such as terrain mapping, environment inspect, 3D city modeling, etc. The precision of LiDAR＇ s productions （DEM, DOM） has been checked through experimentations, which servers practical significance.
