Geographic projection
WebBoth geographic coordinate system's and projected coordinate systems can use WGS84 as the datum they reference. The difference is geographic coordinate systems are not projected, they are in latitude and longitude. In other words, not all measures of latitude and longitude are equivalent - they need to be referenced to a datum - most likely WGS84. WebApr 6, 2015 · Note that an "equidistant" projection typically gives accurate distances only to one (or sometimes two or three) fixed points on the map. Other projections may have relevant properties not shared by these, such as being cylindrical, minimizing the grid convergence, etc.

Webprojection: [noun] a systematic presentation of intersecting coordinate lines on a flat surface upon which features from a curved surface (as of the earth or the celestial sphere) may … WebA geographic coordinate system (GCS) is a reference framework that defines the locations of features on a model of the earth. It’s shaped like a globe—spherical. Its units are angular, usually degrees. A projected …
In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. Projection is a necessary step in creating a two-dimensional map and i… WebA global or spherical coordinate system such as latitude–longitude. These are often referred to as geographic coordinate systems. A projected coordinate system based on a map projection such as transverse …

WebUnlike 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. In a projected coordinate system, locations are identified by x,y coordinates on a grid ...
