The distance measured toward the east between two meridians drawn through the extremities of a course; distance of departure eastward made by a vessel.

Coordinate value by longitudinal reference.

First measurement of a grid reference used to specific the location of a point on a rectangular coordinate system. The distance measured eastward from the origin of a rectangular coordinate system.

One of two geographic coordinate values (the other being northing) used to specify the exact location of a feature on a map. Easting and northings are specified as x,y coordinates receptively for universal transverse mercator and state plane coordinate systems.

(1) The "x" value in a rectangular coordinate system. (2) The distance east of a point location from the west meridian (easting line) of a UTM grid zone.

The distance travelled or the angle of longitude measured eastward from either a defined north-south grid line or a meridian.

The number used in UTM to define how far east or west the position is.

The part of a coordinate (such as longitude) that gives the east-west position.

The horizontal (X) coordinate of a grid coordinate system.

The distance of a point east or west of a zone meridian. Used in several grid coordinate systems: UTS, OSBG, MGRS, etc.

The east-west, X, coordinate in a rectangular coordinate system.

The distance of a point in the units of the coordinate system east of the origin for that system.
