Program Design of Coordinate Transformation Based on Matlab

This article i rst analyzed the coordinate transformation method, and designed the transformation method of WGS84 coordinate system to national or local coordinate. Using Matlab software coordinate transformation programming, it achieved three ellipsoid earth coordinates and Cartesian coordinates, swap, and gauss projection and calculate, seven parameters calculating, seven parameters method of coordinate transformation between dif erent coordinate systems. At the same time, this paper discussed and researched single point coordinate data or batch processing, input or output i le format, coordinate transformation, calculation parameters and verification calculation and other problems, and checked the results of seven parameters of coordinate transformation. The operation interface is simple and beautiful, and the results of operation are reliable.
