Realization and Optimization of Multi-projection Transformation on Remote Sensing image
遥感像片中多投影变换的实现与优化

This paper expounds the fundamental theory of map projection and projection transformation,and analyzes the requirement of raster picture projection transformation and the characteristics differing from vertex projection transformation. The arithmetic of picture projection transformation and its optimization methods are emphasized. The authors take Visual C++ as software platform and develop the system of raster picture projection transformation.
