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
