Examples

.. include:: ../../oneliner_info.rst_

To generate a Mercator map of the track of the cruise 01010007 in the
area 70W to 20E, 40S to 20N, using a Mercator scale of 0.1inch/degree,
label the tracks with 10 points characters, annotate the boundaries
every 10 degrees, draw gridlines every 5 degrees, and mark the track
every day and 1000 km, with ticks every 6 hours and 250 km, and create
a PDF map, enter the following command:

   ::

    gmt mgd77track 01010007 -R70W/20E/40S/20N -Jm0.1 -B10g5 -A10 \
                   -La1da1000kf6hf250k -pdf map
