- Each system excels for different uses, and both help expand and improve GIS mapping. On the one hand, a projected coordinate system is more efficient and easier to work with when mapping objects in space. On the other, a geographic coordinate system is integral in determining the exact spatial point of an object or location in space.

Sep 11, 2020 · Learn more about key differences between projected vs. geographic coordinate reference systems. Geographic coordinate systems span the entire globe (e.g. latitude / longitude), while projected coordinate systems are localized to minimize visual distortion in a particular region (e.g. Robinson, UTM, State Plane).
Sep 7, 2022 · Geographic vs. Projected Coordinate System: The Verdict. Each system excels for different uses, and both help expand and improve GIS mapping. On the one hand, a projected coordinate system is more efficient and easier to work with when mapping objects in space.
Within each zone, a local coordinate system is defined, in which the X-origin is located 500,000 m west of the central meridian, and the Y-origin is the south pole or the equator, depending on the hemisphere. The State Plane system also defines both projection and coordinate system.
Geographic vs. Projected Coordinate Systems Most spatial references fall into one of two categories, a geographic or projected coordinate system. If you are going to work with geospatial data, you need to understand the difference between the two and when it is appropriate to use one over the other.
Geographic vs. projected coordinate systems. This guide outlines two types of coordinate systems: A Geographic Coordinate System (GCS) specifies a datum, spheroid, and prime meridian. A GCS uses coordinates in angular units (e.g. degrees or grads) and is better imagined as a globe than as a flat map.
What’s the Difference between a Projection and a Projected Coordinate System? A projection is one parameter in a PCS. The projection is the mathematical algorithm that defines how to present the round earth on a flat map. All the supported map projections available in ArcGIS are listed in the ArcGIS Pro online help.
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!
