Where is easting 0 northing 0

Southern Hemisphere: The False Eastings X are referenced by setting the central meridian the line going up and down the center of each zone to , meters or kilometers and increasing as you move eastward. It is the same scheme used in the northern hemisphere. The Northings Y are sometimes referenced to setting the equator to a value of 0 meters, but in this case Y becomes more negative the further south you go. Another approach uses False Northings Y' which are referenced by setting the equator to 10,, meters or 10, kilometers and still increasing northward.

That means that all False Northings in the Southern Hemisphere are between 0 meters and 10,, meters 10, kilometers.

When False Northings are used, the southern hemisphere is sometimes identified by assigning it a negative zone number. An illustration of a part of Zone S in the southern hemisphere is given on the right:. As you go northward Y northern or southern hemisphere or Y' southern hemisphere increases in value; and as you go eastward, X increases in value.

In the southern hemisphere, Y is negative. Software that converts between UTM and latitude-longitude can be found on the web see the references. The central meridian in each UTM zone has a scale factor of 0. This is the maximum scale error anywhere within the zone and is the accuracy standard that the system was designed to meet.

The central meridian and lines of true scale in a UTM zone. Scale is less than 1. About the map units Any point within a zone hemisphere can be identified by an x,y coordinate pair that tells you how many meters east and north the point lies from the coordinate system origin. UTM Zone 11N, , meters east, 3,, meters north. Where is the coordinate system origin? The natural origin of a UTM zone is the intersection of its central meridian with the equator, but this origin would assign negative coordinates to some locations.

To avoid this, false easting and northing values are applied. False easting. False northing. North zones. South zones. More about UTM false easting and false northing. False easting is needed to avoid negative x-coordinates west of each zone's central meridian. False northing is needed to avoid negative y-coordinates for all locations in southern hemisphere zones.
