Abstract As the world map which is published on the net by State Bureau of Surveying and Mapping has no the concrete projection parameters and the normal and inverse transformation formulae, it is difficult to project the geoinformation to the map. We derived the formulae of the normal and inverse solution of equivalent difference latitude parallel polyconic projection. Throught choosing the reference points, and computing the projection parameters from the coordinate values of reference points, people can make the transformation of geoinformation according to the normal and inverse transformation formulae, and project the dots, lines or panels to the map easily.
Key words ：
the world map
map projection
equivalent difference latitude parallel
polyconic projection
coordinate transformation
