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.
Learn how to choose and use coordinate systems, map projections, and transformations for spatial data in ArcGIS Pro. Coordinate systems locate data on the surface of the earth, map projections convert them to a flat surface, and transformations convert them between different systems.
Learn how to select an appropriate projected coordinate system for your map based on different projection types and properties. Explore tools and techniques to map global analysis results, polar data, and UTM zones with ArcGIS Pro.
Learn how to flatten a curved surface and project data from a curved to a flat plane using different types of projections. See the distortions, parameters, and examples of equal area, conic, and azimuthal projections. Compare the advantages and limitations of State Plane and UTM zones.
