easting—A linear distance eastwards from the north-south line which passes through the origin (or false origin) of a grid.  Generally, the false origin is selected so that the opposite term, i.e. westing, does not exist in the project survey coordinate system.  Same as x-coordinate.

easting, false—A value assigned the central meridian of a coordinate system to avoid the inconvenience of using negative departures.  See also coordinates, grid.
