GPS定位技术在道路设计中的应用

The application of GPS positioning technology in road design

通过坐标转化将CAD路线方案转换成通用KML文件,再将KML文件导入Google Earth,GPS导航及轨迹记录软件,借助卫星影像照片及GPS定位系统进行现场踏勘,能够准确的了解路线研究区域的地形、地物、地质等情况,便于路线方案的优化调整。同时,借助GPS导航记录软件,还能在外业调查中适时拍摄记录现场实际情况,便于方案汇报、现场影像资料记录、外业资料整理等工作的开展。

Through the coordinate transformation made CAD route scheme converted to common KML file,then imported KML file into Google Earth,GPS navigation and track record software,by virtue of satellite images and GPS positioning system carried out field investigation,able to accurately understand the terrain,ground feature,geology and other conditions of route research region,be convenient for the optimization and adjustment for the route scheme. At the same time,with the aid of GPS navigation record software,could also timely shoot and record the site actual situation in field investigation,so as to facilitate the development of scheme report,field image data recording,field data collation and other works.
