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.

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.
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!
May 21, 2023 · Coordinate systems help us define the positions of features on the earth’s surface. Moreover, map projections are concerned with moving from the three-dimensional world to the two dimensions of a flat map or display.
