摘要： 通过一个Auto CAD的插件程序ACAD2KML，将Auto CAD中的工程图元制作成可导入Google Earth的KML文件，利用Google Earth可便捷地查看工程沿线的地形地物，了解沿线概况，为线性工程的选线及调整提供直观的认识。同时，通过数据线将手持GPS与装有Google Earth的PC机连接，可将GPS的导航功能与Google Earth强大的电子地图功能叠加，为野外踏勘提供便利，提高工作效率。

关键词: 手持GPS, Google Earth, Auto CAD, KML文件

Abstract: Due to the lack of drawings and familiarity with the traffic, the efficiency of the reconnaissance for line projects was low. Through ACAD2KML, a plug-in of AutoCAD, the AutoCAD drawings could be made into a KML file, which can be imported into Google Earth to read the terrain and profile along the project. Intuitive understanding will be obtained for the route selection and route adjustment for  the liner project. At the same time, through connecting handheld GPS with Personal Computer installed with Google Earth by data line, GPS navigation could be associated with Google Earth map to provide convenience for field reconnaissance and to improve work efficiency.

Key words: handheld GPS, Google Earth, Auto CAD, KML File
