Exploration of Projection Distortion to GPS Net and the Method of How to Eliminate the Projection Distortion
XU Tie-lin · Surveying and mapping · 2009
It is not limited by some conditions,such as visible or not,climate and so on,to carry out surveying with GPS.Not only is the efficiency improved greatly,but the labor intensity is reduced greatly.Although the GPS technology is one kind of brand-new technology,its basic theory still could not be separated from the traditional survey theories.This article carried on to the coordinates system transformation introduced that and key aimed at the control net error which the Gauss projection distortion and the elevation surface exceptionally caused to carry on the analysis,and proposed through the example in the engineering survey distorted simple solution.
