RTK测量技术在征占用林地调查中的应用初探

Preliminary application of RTK detection technique in investigation of forest land requisition and occupation

传统的征占用林地面积测量方法存在着测量精度低,成图困难等不足,在分析各种测量技术的基础上,提出了运用GPSRTK技术获取征占用林地面积的新方法。运用该方法在北京至石家庄铁路客运专线项目征占用林地调查中进行了试验。结果表明,与传统测量方法相比具有测量精度高,操作简便能提高工作效率,GPS数据输入GIS可以快速成图等优点。

There is a low measurement accuracy and difficulties in mapping in traditional area measurement methods of forest land requisition and occupation. Based on the analysis in variety of measurement techniques, a new method for obtainning an area of forest land requisition and occupation is proposed using the GPS RTK technology. This method is used in measurement of forest land requisition and occupation of Beijing - Shijiazhuang railway passenger dedicated line project. Results show that compared with the traditional measurement method, the new method has advantages such as high measurement accuracy, easy operation and high effficiency,as well as quick mapping when GPS data inputting into a GIS, etc.
