Abstract

From the geoid to the reference ellipsoid and to map projection,this paper explains the correspondence relation between the irregular earth and the point on the plane map,including the concept of map projection,classification and transformation from one map projection to another,and taking Mapinfo as an example,introduces the setting up of map projection in GIS,forming the foundation for different kinds of spatial analysis.
