摘要
探讨了LIDAR数据密度和DEM精度的关系,介绍了DEM表达的几种常用方法,分析了LIDAR数据可以精简的最大程度。结果证明,LIDAR数据精简降低了数据冗余度,同时也提高了数据存储和处理效率。
This paper discusses the relationship between data density and DEM accuracy, introduces the common methods to generate DEM, and analyzes the data in the extent that can be reduced to the results show that data reduction can not only reduce the redundancy but also enhance the efficiency of storage and data processing.
