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.
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
g.region, r.proj, v.info
