基于LiDAR数据的DEM和矢量自动提取探讨

DEM and Vector Automatic Extraction Based on LiDAR Data

近年来LiDAR技术发展迅速,应用潜力巨大。基于TerraSolid软件环境,简要介绍了LiDAR数据的分类,在此基础上,重点讨论了LiDAR数据的DEM和矢量自动提取的相关问题。由LiDAR数据生成的DEM精度较高,但矢量自动提取还未到实用阶段。

LiDAR technology is developing very fast in recent years, applicable potential is huge. This paper introduces LiDAR data classification in TerraSolid briefly, then emphasizes on the discussion of DEM and vector automatic extraction from LiDAR data. The accuracy of DEM extracted from LiDAR is high, but the vector automatic extraction does not reach practical stage.
