**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.
