A projected coordinate system is defined on a flat, two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles, and areas across the two dimensions. A projected coordinate system is always based on a geographic coordinate system that is based on a sphere or spheroid.

A projected coordinate system, also known as a projected coordinate reference system, a planar coordinate system, or grid reference system, is a type of spatial reference system that represents locations on the Earth using cartesian coordinates ( x, y) on a planar surface created by a particular map projection.

A Projected Coordinate Systems (PCS) is a flat, two-dimensional surface of the Earth. It is based on a sphere or spheroid Geographic Coordinate System. In a PCS identified by x,y coordinates on a grid. The ‘x’ lines represents longitude, and ‘y’ lines represents latitude.

Projected Coordinate Systems are defined on a flat, two-dimensional surface with different projections causing different types of distortions. Various projected coordinate systems have been developed for different regions that provides a common framework to perform spatial analysis.

Feb 27, 2020 · A projected coordinate system (PCS) is a GCS that has been flattened using a map projection. Your data must have a GCS before it knows where it is on earth. Projecting your data is optional, but projecting your map is not. Maps are flat, so your map must have a PCS in order to know how to draw.
