独立坐标系在野外点放样中的实际应用分析

摘要

在野外进行坐标点的放样一般情况可以使用全站仪利用周边控制点进行施工，这种放样方法比较简便，按照设计图得出放样所需的数据即可进行。同时也可以使用RTK（ Real－timekinematic）这一测量方法进行放样。然而，当附近没有控制点、控制点之间不通视或者放样点没有坐标时，要确定这一放样点，则比较困难，如果在点附近建立“独立的坐标系”，任意规定某一方向为北方向，则可以完成点的放样。文章着重阐述这一方法在实践中的应用。%Lofting of the coordinates in the field in general,you can use the total station using the control points of construction,the loft-ing method is straightforward,ant it drew lofting the required data can be achieved in accordance with the drawings.It can also use the RTK ( Real -timekinematic) loft this measuring method.However,when there is no control points and control points near can see or there's no coordinates between lofting points,it is more difficult to determine the lofting points,if it's establishing "independent coordi-nate system"near the points,any one direction as north direction,then you can finish lofting points.This paper focuses on the applica-tion of this method in practice.
