17   Flags:

30   Parameters:
31       map=name [required]
32           Name of vector map
33           Or data source for direct OGR access
34
35       layer=string
36           Layer number or name
37           Vector features can have category values in different layers.  This
38           number  determines  which  layer  to use. When used with direct OGR
39           access this is the layer name.
40           Default: 1
41
42       option=string [required]
43           Value to calculate
44           Options: area, length, coor
45
46       units=string
47           Units
48           Options: miles, feet, meters, kilometers, acres, hectares, percent
49
50       sort=string
51           Sort the result
52           Options: asc, desc
53           asc: Sort in ascending order
54           desc: Sort in descending order
55

DESCRIPTION

57       v.report generates a table showing the area present in each of the cat‐
58       egories of a user-selected data layer.
59
60       Area  is  given  in hectares, square meters, and square kilometers.  If
61       the units option is used, area is given  in  acres,  square  feet,  and
62       square miles.
63
64       Feet  and acre units are always reported in their common versions (i.e.
65       the International Foot, exactly 5280 feet in a  mile),  even  when  the
66       location’s standard map unit is the US Survey foot.
67
68       v.report  works  on the full map data; therefore, the current region is
69       ignored. If you wish to spatially limit the statistics,  a  map  subset
70       must  be  created with v.in.region and v.overlay, and then run v.report
71       on the new map.
72

EXAMPLE

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