SYNOPSIS

       r3.mask
       r3.mask --help
       r3.mask map=string  [maskvalues=val[-val][,val[-val],...]]   [--help]  [--verbose]  [--quiet]  [--ui]

   Flags:
       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       map=string [required]
           3D raster map with reference values

       maskvalues=val[-val][,val[-val],...]
           List of cell values to be masked out

DESCRIPTION

       r3.mask  facilitates  the creation of a raster3d "MASK" map to control raster3d operations.  The raster3d
       map is used as the reference map.  Cells in the mask are marked as "mask out" if the  corresponding  cell
       in map contains a value in the range specified with maskvalues.

NOTES

       Before a new 3D-mask can be created the existing mask has to be removed with g.remove.
