DESCRIPTION

71       d.grid overlays a grid of user-defined size and  color  in  the  active
72       display  frame  on  the graphics monitor.  The grid can be created as a
73       standard rectangular grid or a geographic grid. The grid will  overlay,
74       not overwrite, the contents of the active display frame.
75
76       d.grid  can  be  run  non-interactively  or interactively.  If the user
77       specifies the grid size and (optionally) the grid color on the  command
78       line  the program will run non-interactively; if no grid color is given
79       the default will be used.  Alternately, the user may simply type d.grid
80       on the command line; in this case, the program will prompt the user for
81       parameter values using the standard GRASS graphical user interface.
82

NOTES

84       d.grid will not erase grids already displayed in  the  active  graphics
85       display  frame  by previous invocations of d.grid; multiple invocations
86       of d.grid will therefore result in the drawing of multiple grids inside
87       the  active  graphics frame.  (A command like d.erase, which erases the
88       entire contents of the active display frame, must be run to erase  pre‐
89       viously drawn grids from the display frame.)
90
91       If  the  user  provides a -g flag a geographic (projected) grid will be
92       drawn. With the -g flag the size argument accepts both decimal  degrees
93       and  colon  separated ddd:mm:ss coordinates (eg. 00:30:00 for half of a
94       degree).
95
96       A geographic grid cannot be drawn for a latitude/longitude or  XY  pro‐
97       jection.
98
99       Colors may be standard named GRASS colors (red, green, aqua, etc.) or a
100       numerical R:G:B triplet, where component values range from 0-255.
101
102       The grid drawing may be turned off by using the -n flag.
103       The border drawing may be turned off by using the -b flag.
104       The coordinate text may be turned off by using the -t flag.

EXAMPLES

107       To draw a red geographic grid with 30 minute grid spacing run either of
108       the following:
109         d.grid -g size=00:30:00 color=red
110        or
111         d.grid -g size=0.5 color=255:0:0
112         To draw a blue standard rectangular grid at a 500 (meter) spacing run
113       the following:
114         d.grid size=500 color=blue
