The coordinates are most commonly associated with the Universal Transverse Mercator coordinate system (UTM), which has unique zones that cover the Earth to provide detailed referencing. ![]() However, other units (e.g., survey feet) are also used. When using common projections such as the transverse Mercator projection, these are distances projected on an imaginary surface similar to a bent sheet of paper, and are not the same as distances measured on the curved surface of the Earth.Įasting and northing coordinates are commonly measured in metres from the axes of some horizontal datum. Easting is the eastward-measured distance (or the x-coordinate) and northing is the northward-measured distance (or the y-coordinate). Įasting and northing are geographic Cartesian coordinates for a point. UTM zones on an equirectangular world map with irregular zones in red.
