Based on the overview and analysis on major methods about map projection transformation, the author thinks that the inverse transformation method is better than other methods in dealing with free transformation among several projections. Furthermore the computer implementation process and some key topics including map projection system, map projection parameters, algorithm optimization and error computation and control in the transformation process are discussed in this paper.
