                                  What Is Geographical Location?

There are two types of co-ordinates system is used in the GIS coordinate system.
1. Geographical Coordinate system 2. Projected coordinate system
1. Geographical Coordinate System- Geographical coordinate system measures the position by taking the account the curvature of the earth's surface. 



2. Projected Coordinate System. The projected coordinate system is the transformation of GIS to flat 2D. This is a linear measurement coordinate. It is also used in cad drawing.
