基于航飞LIDAR数据制作数字线划图方法探索

摘要

Some large projects gather the mass data using aircraft flight LIDAR system in the early phase , and the data is 3D point cloud data and DOM image data .To make the digital line graphic of whole project area , it is of low efficiency , which is almost impos-sible to complete the work using traditional methods .Because of the massive data which has made traditional AutoCAD software plat-form overwhelmed , for this reason , we must study and explore the new method for the production line map using the GIS method .%一些大型的工程项目在前期使用航飞LIDAR系统采集地面数据，获取了大量的三维点云数据和DOM影像数据，要制作该项目全区域的线划图，使用传统的制图方法，不仅效率低，而是几乎不可能完成该项工作。因为海量数据已经让传统的AutoCAD平台制图软件不堪重负，基于此原因，必须研究探索新的方法，就是使用 GIS方法来生产线划图。
