NAME  - Reports geometry statistics for vectors.


       vector, report, statistics

SYNOPSIS help  [-rs]  map=string   [layer=integer]  option=string  [units=string]   [--verbose]

           Reverse sort the result

           Sort the result

           Verbose module output

           Quiet module output

           Name of input vector map

           Layer number
           Default: 1

           Value to calculate
           Options: area,length,coor

           Options: mi,miles,f,feet,me,meters,k,kilometers,a,acres,h,hectares,p,percent

DESCRIPTION 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 location's standard map unit is the US
       Survey foot. 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 and
       v.overlay, and then run on the new map.


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