DESCRIPTION
d.grid overlays a grid of user-defined size and
color in the active display frame on the graphics monitor.
The grid will overlay, not overwrite, the contents of the
active display frame.
d.grid can be run non-interactively or
interactively. If the user specifies the grid
size and (optionally) the grid color on
the command line the program will run non-interactively; if
no grid color is given the default will be used.
Alternately, the user may simply type d.grid on the
command line; in this case, the program will prompt the
user for parameter values using the standard GRASS user
interface described in the manual entry for
parser.
NOTES
d.grid will not erase grids already displayed in
the active graphics display frame by previous invocations
of d.grid; multiple invocations of d.grid
will therefore result in the drawing of multiple grids
inside the active graphics frame. (A command like
d.erase, which erases the
entire contents of the active display frame, must be run to
erase previously drawn grids from the display frame.)
Currently, the grid size can only be drawn in the units of
the map coordinate system used by the current GRASS
location.
