Name for output vector map

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
