DESCRIPTION

113       d.northarrow  displays a north arrow symbol at the given screen coordi‐
114       nates. If no coordinates are given it will draw the north arrow in  the
115       bottom right of the display. It can draw the north arrow in a number of
116       styles (see the wiki page for details).  With certain styles  of  north
117       arrow label ’N’ is displayed by default, and can be changed with option
118       label, for example for different languages.  The label  can  be  hidden
119       with -t flag.
120
121       North  arrow  can be rotated, for example to align with true north, not
122       grid north.  The angle in degrees counter-clockwise (or radians with -r
123       flag)  can be specified with option rotation. Label is rotated together
124       with the arrow, unless flag -w is specified.
125

EXAMPLES

127       Display a north arrow symbol as a basic compas with  label  NORTH,  ro‐
128       tated by 8 degrees with label, with black line and gray fill:
129       d.mon wx0
130       d.northarrow style=basic_compas rotation=8 label=NORTH -w color=black fill_color=gray
131       d.mon -r
