**geographic coordinate system**is displayed as if a degree is a linear unit of measure. This method is basically the same as the Plate Carrée projection. Learn more about the Plate Carrée projection**Geographic****coordinate**systems describe how locations on the earth are placed on a hypothetical reference spheroid. They use angular units, such as degrees, to assign locations to coordinates on a reference spheroid. There is more than one**geographic coordinate system**because each is meant to best fit certain portions of the earth.The

**World Geodetic System**(WGS) is a standard for use in cartography, geodesy, and satellite navigation including GPS.This standard includes the definition of the**coordinate****system**'s fundamental and derived constants, the normal gravity Earth Gravitational Model (EGM), a description of the associated World Magnetic Model (WMM), and a current list of local datum transformations.Sep 03, 2019 ·
