easting
A rectangular (x,y) coordinate measurement of distance east from a north-south reference line, usually a meridian used as the axis of origin within a map zone or projection.

 


Eastings:
The complete Easting value is placed as close to each corner as possible without interfering with any other border information. Its true position is dependent on the actual grid placement within the map.

Eastings are measured from the central meridian (with a 500km false easting to insure positive coordinates). Northings are measured from the equator (with a 10,000km false northing for positions south of the equator).

Within any given SPC zone, X-Y coordinates are given in eastings and northings. A central meridian passes each zone and is given a false easting of 2 million feet. A false northing of 0 feet is established below the southern limit of each zone.

The UTM easting coordinate (the X coordinate) for a feature is the distance in meters east or west from the central meridian of the UTM zone.

UTM coordinates are typically given with the zone first, then the easting, then the northing. So, in UTM coordinates, Red Hill is located in zone twelve at 328204 E (easting), 4746040 N (northing).

Positions are measured using Eastings and Northings, measured in meters, instead of Latitude and Longitude. Eastings start at 500,000 on the centre line of each zone.

The colour-coded map shows the maximal absolute error of a rigid-body shift in the image when the components of shift, both Northing and Easting, were determined from a single point located at the center of the map sheet.

A grid is a rectangular system with the easting and the northing lines forming right angles at the point of intersection.

For example, if the destination Universal Address is NAC: GH8JS QFGSL and the current location is NAC: 8H8JK QFGSD, you can see the differences between these two Universal Addresses: seven grid cells of Level 5 NAC grid in easting and six grid cells ...

Within each zone the central meridian is given an Easting value of 500,000 metres. The equator is designated as having a Northing value of 0 for northern hemisphere coordinates.

There is a false origin defined at 400,000, -100,000 such that the central meridian is the Zero easting of the National Grid - which is also aligned to the 2 degree West meridian of Longitude. Additionally, the scale along the central meridian is 0.

By providing an SPC easting (x) and northing (y), the state name, and the zone number, any location in the United States can be identified by a unique coordinate value. SPC Zone boundaries follow state and county boundaries.

orthogonal system A coordinate system in which the X (Easting), and the Y (Northing) axes are scaled the same and consistently in all parts of the map, and the curvature of the earth is ignored.

New option for alignment tie by co-ordinates (northing and easting) has been provided in the alignment dialog in ABC Wizard.

If they are negative, you'll have to add a large offset to each value (creating a False Easting and False Northing). ArcGIS doesn't like negative numbers, and you'll get a "Warning: Inconsistent Extent" message if you try and open the XY coords.

Origin - The reference point in a coordinate system at which both the easting and northing (i.e. x and y) values are equal to zero.

The easting coordinates are measured from an artificial reference line drawn parallel and 500,000 meters to the west of the zone's central meridian.

is designated 0 for quadrangles in the northern hemisphere, and 10,000,000 for quadrangles in the southern hemisphere. Since the distance from poles to Equator is approximately 10,000 km, such offset origins ensure coordinates (called false eastings ...

In our Data Frame Proeprties modify the coordinate system properties, Changing the False Easting to 0, and the False Northing to -143000. This basically shifts our coordinates closer to the origin.
