用差分GPS进行线路纵横断面测绘数据处理模型

Model of Data Processing for Surveying and Mapping of Section by Using RTKGPS and Total Station

利用GPS或全站仪观测速度快、自动化记录、数据通迅方便等特点进行纵横断面测量 ,建立数据处理模型 ,实现断面上里程点和横断面上点的自动搜索 。

There are many merits to survey with GPS and Total Station, such as quickness, automatic, well communication and etc. So, it is a good way to survey with RTKGPS or Total Station. The author makes use of these advantages to build up the data model and to search the mileages of the section automatically, and further more to draw out the map of this section automatically.
