NAME

       v.report  - Reports geometry statistics for vector maps.

KEYWORDS

       vector, geometry, statistics

SYNOPSIS

       v.report
       v.report --help
       v.report   map=name    [layer=string]    option=string    [units=string]     [sort=string]
       [--help]  [--verbose]  [--quiet]  [--ui]

   Flags:
       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   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: 1

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

       units=string
           Units
           Options: miles, feet, meters, kilometers, acres, hectares, percent

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

DESCRIPTION

       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 location’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.

EXAMPLE

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