Classifi cation of Map Projections
Map projections are classifi ed on the following criteria:
• Method of construction
• Development surface used
• Projection properties
• Position of light source
Classifi cation based on Methods of Construction
Given below are the projections that are based on the method of construction:
a). Perspective Projections:
These projections are made with the help of shadow cast from an illuminated globe on to a developable surface.
b). Non Perspective Projections:
A developable surface is only assumed to be covering the globe and the construction of projections is done using mathematical calculations.
