<h2>DESCRIPTION</h2>

<em>v.report</em> generates a table showing the area present in 
each of the categories of a user-selected data layer.
<p>Area is given in hectares, square meters, and square kilometers.
If the units option is used, area is given in acres, square feet,
and square miles.
<p>Feet and acre units are always reported in their common versions
(i.e. the International Foot, exactly 5280 feet in a mile), even
when the location's standard map unit is the US Survey foot.
<p><em>v.report</em> works on the full map data; therefore, the current
region is ignored. If you wish to spatially limit the statistics,
a map subset must be created with <em>v.in.region</em> and 
<em>v.overlay</em>, and then run <em>v.report</em> on the new map.


<h2>EXAMPLE</h2>

North Carolina sample dataset:
<div class="code"><pre>
v.report zipcodes_wake option=area units=hectares
</pre></div>

In the output, there is an extra column added containing the results.
