To solve the question of low accuracy spot position in the road lofting of survey,Qing'An to the SuiHua section(The kilometer station number is from K165+150 to 230+950),we used GPS RTK technology carry on the lofting of route's spot position,and gathered the elevation which RTK obtains,at the same time,we used the ordinary level survey method to carry on the leveling elevation for the spot position.After that,we carried on the precision contrastive analysis and make satisfying progress,regardless of the plane or the elevation.The paper mainly introduces the principle of the GPS survey,also elaborates the application and the effect of GPS in the engineering control survey and RTK technology lofting actually through the project.The paper analysis and compares the GPS elevation survey precision,summarizes the experience of GPS in the route project application,and provides the reference for the related project.
