Creating MASK from vect

[Donald Newcomb]

My suggestion would be to go back to the vector file in v.digit. Add a
loop around your study area (either land or sea) and label that as a
polygon of type 1. Then convert the polygon vector file to raster. This
will produce a mask file that will have one value over water and another
over land.
