DESCRIPTION

104       d.northarrow  displays a north arrow symbol at the given screen coordi‐
105       nates. If no coordinates are given it will draw the north arrow in  the
106       bottom right of the display. It can draw the north arrow in a number of
107       styles (see the wiki page for details).  With certain styles  of  north
108       arrow label ’N’ is displayed by default, and can be changed with option
109       label, for example for different languages.  The label  can  be  hidden
110       with -t flag.
111
112       North  arrow  can be rotated, for example to align with true north, not
113       grid north.  The angle in degrees counter-clockwise (or radians with -r
114       flag)  can be specified with option rotation. Label is rotated together
115       with the arrow, unless flag -w is specified.
116

EXAMPLES

118       Display a north arrow symbol  as  a  basic  compas  with  label  NORTH,
119       rotated by 8 degrees with label, with black line and gray fill:
120       d.mon wx0
121       d.northarrow style=basic_compas rotation=8 label=NORTH -w color=black fill_color=gray
122       d.mon -r
