摘要
针对线路工程提出利用若干个 GPS和水准高程点建立一个拟合面作为高程基准面 ,这样 GPS高程经拟合后可获得相对于拟合基准面的准确高程 ,水准测量附合于 GPS点进行闭合差的调整 ,充分利用了 GPS的高程信息 ,有益于在线路工程中用
In this paper,for the linear engineering leveling routes,a new method is proposed for founding a fit height datum plane based on several GPS and leveling points,so the accurate leveling values related to the fit height system can be obtained by surveying.The normal leveling results are closed to the GPS points and adjusted accordingly.So the height information in the GPS data can be used efficiently and the GPS surveying used can be used to replace the leveling in the road engineering.
