摘要
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。
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 overwhehned, for this reason, we must study and explore the new method for the production line map using the GIS method.
