 <h2>NOTES</h2>
+Measures of lengths and areas are always reported in meters, unless the
+<em>unit</em> parameter is set.
 The units <em>miles</em>, <em>feet</em>, <em>meters</em> and
 <em>kilometers</em> are square for <em>option=area</em>.
 <p>Feet and acre units are always reported in their common versions
