Abstract
THE problem of reducing the sphere to a plane surface has ever been a difficulty. This realisation has led cartographers to adopt the policy of constructing a map for a specific purpose. The most important features which have to be embodied in maps may be classified in three categories: (1) exactness of shape; (2) exactness of area; (3) exactness of relative position. Whichever of these features will be required is decided by the purpose of the map, and when this has been decided a map is constructed on an appropriate projection. The required feature is embodied in the map, the others are ignored, with the result that distortion in some respect is usually apparent.
