UTM ² Conformal projection (shapes are preserved) ² Cylindrical surface ² Zones are 6 degrees of longitude wide ² The earth is divided into 60 UTM zones. ² Each zone has a Central Meridian ( λ o ) ² Zones are 6° wide, and go from ‘pole’ to ‘pole’ ² Sixty zones allows the earth to be projected onto maps with minimal distortion. ² Scale distortion is 0.9996 along the central meridian of a zone ² There is no scale distortion along the the standard meridians ² Scale is no more than 0.1% in the zone ² Scale distortion gets to unacceptable levels beyond the edges of the zones 30
