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. 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
