<em>v.report</em> generates a table showing the area present in
4
each of the categories of a user-selected data layer.
6
Area is given in hectares, square meters, and square kilometers.
7
If the units option is used, area is given in acres, square feet,
10
Feet and acre units are always reported in their common versions
11
(i.e. the International Foot, exactly 5280 feet in a mile), even
12
when the location's standard map unit is the US Survey foot.
14
<em>v.report</em> works on the full map data; therefore, the current
15
region is ignored. If you wish to spatially limit the statistics,
16
a map subset must be created with <em>v.in.region</em> and
17
<em>v.overlay</em>, and then run <em>v.report</em> on the new map.

North Carolina sample dataset:
23
<div class="code"><pre>
24
v.report zipcodes_wake option=area units=hectares
27
In the output, there is an extra column added containing the results.

<a href="v.in.region.html">v.in.region</a>,
33
<a href="v.to.db.html">v.to.db</a>,
34
<a href="v.overlay.html">v.overlay</a>
