False easting

false easting An adjustment constant added to easting coordinate values to eliminate negative numbers. (See also: easting.) false northing An adjustment constant added to northing coordinate values to eliminate negative numbers. (See also: northing.) ...

False Easting, x coordinate of map(-projection) origin y0 False Northing, y coordinate of map origin k0, scale Scale factor at central meridian [0.1, 10] lam0 Central meridian, longitude of map origin (-180, 180) phi0 ...

By definition the Central Meridian is assigned a false easting of 500,000 meters. Any easting value greater than 500,000 meters indicates a point east of the central meridian.

For locations in the Northern Hemisphere, the origin is assigned a false easting of 500,000 and a false northing of 0. For locations in the Southern Hemisphere, the origin is assigned a false easting of 500,000 and a false northing of 10,000,000.1 ...

UTM Zones 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). UTM Zone 14 ...

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.

All zones have their origin at the equator, use the meter as the system unit, and have a false easting of 500,000 meters and a false northing of 0. A scale reduction factor of 0.9996 is used on all zones.

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.

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.
