Map Projections and Distortion
Map projections produce distortion in one or more spatial properties:•Shape, area, distance, and direction•Specific projections eliminate or minimize distortion

Projection not Important Business applications
•Not of critical importance. •Concerned with the relative location of different features
On large scale maps - street maps•Distortion may be negligible •Map covers only a small part of the Earth's surface.
