1:xxxxx, or width in UNIT (upper case modifier). UNIT is cm,
inch, or m, depending on the <b><A HREF="gmtdefaults.html#MEASURE_UNIT">MEASURE_UNIT</A></b> setting in
.gmtdefaults4, but this can be overridden on the command
line by appending <b>c</b>, <b>i</b>, or <b>m</b> to the
scale/width value. When central meridian is optional,
default is center of longitude range on <b>−R</b>
option. Default standard parallel is the equator. For map
height, max dimension, or min dimension, append <b>h</b>,
<b>+</b>, or <b>-</b> to the width, respectively.</p></td></tr>
