Geographic vs Projected Coordinate Systems - Esri
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.
What are projected coordinate systems?—ArcMap | Documentation
A projected coordinate system is defined on a flat, two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has ...

Projections and Coordinate Systems - UW Courses Web Server
Projections and coordinate systems are a complicated topic in GIS, but they form the basis for how a GIS can store, analyze, and display spatial data.
Exploring Coordinate Systems and Map Projections - Propeller
Projected vs. geographic coordinate systems. Technically, there are two classes of coordinate reference systems: geographic and projected coordinate systems.
Projected coordinate systems - IBM
A projected coordinate system is a flat, two-dimensional representation of the Earth. It is based on a sphere or spheroid geographic coordinate system, ...
Coordinate Systems: What's the Difference? - Esri

2.3 Datums, Coordinate Systems, and Map Projections - OPEN SLCC
Map projections are concerned with moving from the three-dimensional world to the two dimensions of a flat map or display.
8. Coordinate Reference Systems — QGIS Documentation ...
Map projections try to portray the surface of the earth, or a portion of the earth, on a flat piece of paper or computer screen. In layman's term, map ...
