DESCRIPTION creates a new vector map from current region extent.

If the output of 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 output=soils_Kfactor_bbox map=soils_Kfactor_bbox


g.region, r.proj,
