NAME
v.report - Reports geometry statistics for vector maps.
KEYWORDS
vector, geometry, statistics
SYNOPSIS
v.report
v.report help
v.report [-rs] map=string [layer=string] option=string [units=string] [--verbose] [--quiet]
Flags:
- -r
- Reverse sort the result
- -s
- Sort the result
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- map=string
- Name of input vector map
- Data source for OGR access
- layer=string
- Layer number or name
- A single vector map can be connected to multiple database tables. This number determines which table to use. Layer name for OGR access.
- Default: 1
- option=string
- Value to calculate
- Options: area,length,coor
- units=string
- Units
- Options: miles,feet,meters,kilometers,acres,hectares,percent
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
Spearfish example:
v.report fields option=area units=hectares
