Spatial reference system
- A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection.

What are projected coordinate systems? 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.
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.
Definition. A Projected Coordinate System (PCS) is a type of spatial reference system that represents the three-dimensional earth on a two-dimensional plane. It employs mathematical techniques to convert spherical earth surfaces into flat maps while minimizing distortion as much as possible.
Projected coordinate systems are planar systems that use linear measurements for the coordinates rather than angular units. A projected coordinate system is composed of a geographic coordinate system and a map projection together.
Mar 3, 2020 · A projected coordinate system (PCS) is flat. It contains a GCS, but it converts that GCS into a flat surface, using math (the projection algorithm) and other parameters. Its units are linear, most commonly in meters. A GCS is necessary for data to know where exactly on earth’s surface it is located.
The State Plane Coordinate System is a set of individual projections, each covering a portion of a state. State Pane zones are defined by county boundaries. Each zone is an individual projection; quite a difference in extent compared to the global cylindrical projections!
