UTM Universal Transverse Mercator Cylindrical Projection 

SYNOPSIS  
function [out1,out2,savepts] = utm(mstruct,in1,in2,object,direction,savepts)


DESCRIPTION  
UTM Universal Transverse Mercator Cylindrical Projection This is a conformal projection with parameters chosen to minimize distortion over a defined set of small areas. It is not equal area, equidistant, or perspective. Scale is true along two straight lines on the map approximately 180 kilometers east and west of the central meridian, and is constant along other straight lines equidistent from the central meridian. Scale is less than true between, and greater than true outside the lines of true scale. The UTM system divides the world between 80 degrees S and 84 degrees N into a set of quadrangles called zones. Zones generally cover 6 degrees of longitude and 8 degrees of latitude. Each zone has a set of defined projection parameters, including central meridian, false eastings and northings and the reference ellipsoid. The projection equations are the GaussKrueger versions of the transverse Mercator. The projected coordinates form a grid system, in which a location is specified by the zone, easting and northing. The UTM system was introduced in the 1940's by the U.S. Army. It is widely used in topographic and military mapping.
