摘要
Abstract
Spatial information is one of the important components of national information resources.It plays more and more important role.As parts of spatial data,acquisition and update of geomorphic data are very important. Since the advent of airborne Lidar,its applications continue to expand.With the rapid update geomorphic data for research purposes,after deep analysis on the features of airborne Lidar data and update process of geomorphic da-ta,fast update method based on airborne Lidar data has been put forward.Specific steps and the core technology of this method have been introduced.At the same time,data preprocessing based on secondary development of CAD has been carried out,which will greatly improve the efficiency of updating landform data.关键词
