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> Spearfish example: <div class="code"><pre> v.report fields option=area units=hectares </pre></div> <h2>SEE ALSO</h2> <em> <a HREF="v.in.region.html">v.in.region</a>, <a HREF="v.to.db.html">v.to.db</a>, <a HREF="v.overlay.html">v.overlay</a> </em> <H2>AUTHOR</H2> Markus Neteler, GDF Hannover <p> <i>Last changed: $Date: 2007-11-20 10:34:59 +0100 (Tue, 20 Nov 2007) $</i> <HR> <P><a href="index.html">Main index</a> - <a href="vector.html">vector index</a> - <a href="full_index.html">Full index</a></P> <P>© 2003-2008 <a href="http://grass.osgeo.org">GRASS Development Team</a></p> </body> </html>
