v.report - Reports geometry statistics for vector maps.

       Markus Neteler, GDF Hannover

v.report  generates  a  table  showing the area present in each of the categories of a user-selected data
       layer.

       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.

       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 coordinate reference system’s standard map  unit  is  the  US  Survey
       foot.

       v.report  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 v.in.region and v.overlay, and then run  v.report
       on the new map.

       North Carolina sample dataset:
       v.report zipcodes_wake option=area units=hectares
       In the output, there is an extra column added containing the results.

   Parameters:map=name[required]
           Name of vector map
           Or data source for direct OGR access

       layer=string
           Layer number or name
           Vector features can have category values in different layers. This number determines which  layer  to
           use. When used with direct OGR access this is the layer name.
           Default: 1option=string[required]

           Options: asc,descasc: Sort in ascending order

       separator=character
