Feb 27, 2020 · What is the difference between a geographic coordinate system (GCS) and a projected coordinate system (PCS) anyways? Here’s the short answer: A GCS defines where the data is located on the earth’s surface. A PCS tells the data how to draw on a flat surface, like on a paper map or a computer screen.
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.
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).
A projection and a projected coordinate system are not the same thing. A projection is one parameter in a projected coordinate system. Other parameters include a geographic coordinate system, a linear unit, and a set of parameters that depend on the selected projection (central meridian, scale factor, and so on).
Oct 6, 2022 · A geographic coordinate system is constituted by a datum (DATUM), a prime meridian (PRIMEM), and unit (UNIT). The datum is constituted by a ellipsoid model (SPHEROID) and a anchor point. An example is: WGS84 coordinate system with unique EPSG code 4326; Projected Coordinate System
Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles, and areas across the two dimensions. A projected coordinate system is always based on a geographic coordinate system that is based on a sphere or spheroid.
