27 de feb. de 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.
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 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.
11 de sept. de 2020 · 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).
Projected coordinate systems are planar systems that use linear measurements for the coordinates rather than angular units. A projected coordinate system is composed of a geographic coordinate system and a map projection together.
3 de mar. de 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 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.
