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 location.
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
