| Abstract: | A new method of the transformation mathematic basis(projection transformation) of raster map has been studied in this paper. The authors discuss the detailed transformation process of the whole_block image and the split_block images, then study the piecing of split_block images. At last, based on the above way, the authors make some experiments. |
