NAME
v.report - Reports geometry statistics for vector maps.
KEYWORDS
vector, geometry, statistics
SYNOPSIS
v.report
v.report --help
v.report [-cd] map=name [layer=string] option=string [units=string]
[sort=string] [--help] [--verbose] [--quiet] [--ui]
Flags:
-c
Do not include column names in output
-d
Report for geometries with no database records
--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 ac-
cess 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 cat-
egories 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 lo-
cation’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.
