<p>UTM projections are really the <a class="reference internal" href="tmerc.html#tmerc"><span class="std std-ref">Transverse Mercator</span></a>
to which specific parameters, such as central meridians, have been applied.
The Earth is divided into 60 zones each generally 6° wide in longitude.
Bounding meridians are evenly divisible by 6°, and zones are
numbered from 1 to 60 proceeding east from the 180th meridian from Greenwich
