NAME

v.in.region - Creates a vector polygon from the current region extent.

KEYWORDS

vector, geometry

SYNOPSIS

v.in.region
v.in.region --help
v.in.region [-d] output=name [type=string] [cat=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-d: Densify lines using region resolution
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

output=name [required]: Name for output vector map
type=string: Select type: line or area
Options: line, area
Default: area
cat=integer: Category value
Default: 1

DESCRIPTION

v.in.region creates a new vector map from current region extent.

If the output of v.in.region is to be used for raster reprojection, the -d flag should be used after setting the region to the raster map to be reprojected with r.proj.

EXAMPLE

The example is based on the North Carolina sample data. To create a bounding box vector map based on a raster map, the computational region is first set to the raster map. Then a vector bounding box is created based on the actual computational region (in this case precisely reflecting the pixel geometry of the raster map), resulting in a new vector polygon:

g.region raster=soils_Kfactor -p
v.in.region output=soils_Kfactor_bbox
v.info map=soils_Kfactor_bbox
