37   Parameters:
38       map=name [required]
39           Name of vector map
40           Or data source for direct OGR access
41
42       layer=string
43           Layer number or name
44           Vector  features can have category values in different layers. This
45           number determines which layer to use. When used with direct OGR ac‐
46           cess this is the layer name.
47           Default: 1
48
49       option=string [required]
50           Value to calculate
51           Options: area, length, coor
52
53       units=string
54           Units
55           Options: miles, feet, meters, kilometers, acres, hectares, percent
56
57       sort=string
58           Sort the result
59           Options: asc, desc
60           asc: Sort in ascending order
61           desc: Sort in descending order
62
63       separator=character
64           Field separator
65           Special characters: pipe, comma, space, tab, newline
66           Default: pipe

DESCRIPTION

69       v.report generates a table showing the area present in each of the cat‐
70       egories of a user-selected data layer.
71
72       Area is given in hectares, square meters, and  square  kilometers.   If
73       the  units  option  is  used,  area is given in acres, square feet, and
74       square miles.
75
76       Feet and acre units are always reported in their common versions  (i.e.
77       the International Foot, exactly 5280 feet in a mile), even when the lo‐
78       cation’s standard map unit is the US Survey foot.
79
80       v.report works on the full map data; therefore, the current  region  is
81       ignored.  If  you  wish to spatially limit the statistics, a map subset
82       must be created with v.in.region and v.overlay, and then  run  v.report
83       on the new map.
84

EXAMPLE

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