摘　　要：如何实现对机载激光雷达点云数据快速、准确地提取地形数据是当前急需解决的问题。本文介绍了LiDAR数据特点及处理流程,利用ArcGIS10.1平台的扩展软件LP360对LiDRA点云数据进行地物分类,并通过Python脚本语言实现直接由点云数据提取等高线。实验表明:LP360对海量点云数据分类具有稳定性高、可视可操作性强、速度快,对于大批量生产作业,切实可行。Problems that how to achieve the airborne LiDAR point cloud data quickly and accurately to extract the terrain data are in urgent need to be solved. This article describes the characteristics of LiDAR data and process flow, conducts the terrain classification of LiDAR point cloud data by using ArcGIS10. I platform extension software （LP360）, and extracts the contour through the Python scripting language directly from point cloud data. Experiments show that the LP360 can deal with mass points cloud data classification with a high stability, strong visual maneuverability and hizh soeed for mass Droduction which i~ f^ihl,~
