| Abstract: | In this paper, we have studied the theory of projection distortion by using the differential matrix of operators, the necessary and sufficient conditions of conformal, authalic or equidistant projection are obtained meanwhile, and the forward and inverse transformations of conformal or authalic cylindrical projection and normal conical conformal projection are searched after by using these conditions. |
