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.
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.
Your job when choosing the appropriate coordinate system for you data and project, is to focus on your area of interest and to choose the math that preserves the metric you are most interested in measuring.
May 21, 2023 · The essential cartographic considerations are map scale, coordinate systems, and map projections. Map scale is concerned with reducing geographical features of interest to manageable proportions. Coordinate systems help us define the positions of features on the earth’s surface.
Mar 3, 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 GCS is necessary for data to know where exactly on earth’s surface it is located.
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.
Coordinate Systems. Once map data are projected onto a planar surface, features must be referenced by a planar coordinate system. The geographic system (latitude-longitude), which is based on angles measured on a sphere, is not valid for measurements on a plane.
A projected coordinate system is a reference system for identifying locations and measuring features on a flat (map) surface. It consists of lines that intersect at right angles, forming a grid. Projected coordinate systems, which are based on Cartesian coordinates, have an origin, an x and a y axis, and a unit for measuring distance.
Oct 19, 2023 · The plane coordinates are the projection of the sphere from a 3-D view into a 2-D plane view. The latitude and longitude coordinates can be converted directly into different plane coordinates. The conversion from one coordinate to another is extremely important in any GIS work.
