Discussion on applicability of transformation model for common coordinate system in GPS
Shu Guodong · Yangtze River · 2010
As the geographical data surveyed under different coordinates in China,in the application of GPS engineering survey,the different coordinate system must be transformed.Therefore,it is meaningful to study the method to transform WGS84 coordinate to geodetic coordinate system.The precision differences calculated by Bulsa model,Molodenski-Badekas model,and similar transformation model are discussed.We propose method and principle of using corresponding model for different regions to solve the problems of coordinate system transformation,which has a practical value.
