NAME  - Reports geometry statistics for vector maps.


       vector, geometry, statistics

SYNOPSIS --help   map=name    [layer=string]    option=string    [units=string]     [sort=string]
       [--help]  [--verbose]  [--quiet]  [--ui]

           Print usage summary

           Verbose module output

           Quiet module output

           Force launching GUI dialog

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

           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: 1

       option=string [required]
           Value to calculate
           Options: area, length, coor

           Options: miles, feet, meters, kilometers, acres, hectares, percent

           Sort the result
           Options: asc, desc
           asc: Sort in ascending order
           desc: Sort in descending order

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.
