Overview
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.
Examples
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 -pv.in.region output=soils_Kfactor_bboxv.info map=soils_Kfactor_bbox
