Algorithm Analysis And Application Research Among PE-90, WGS-84, BEJ-54 Coordindte Systems Transformation

The shape of the Earth and usual coordinate systems are introduced. The coordinate systen transformation method is researched. Especial transformation method of different coordinat systems, Geocentric Cartesian coordinates of the same coordinate system and it Geodetic system , Geocentric Cartesian coordinates of the different earth models, Geodetic system am map(plane) are researched.The simple- models and the application with Geocentric Cartesian coordinates and Geodetic system among WGS-84, PE-90 and BEIJING 54 coordinate systems are studied. Also the transformation algorithm between GPS coordinate and electronic map coordinate is given in local district, for example Xiamen.It shows that this study provides good theory proof and simple algorithm of high accuracy connecting electronic map in maritime or land over theory analysis, computer simulation and experiment.
