    Re: GPS trick: compass rose waypoint

    I took some courses in Cartography in college about 16 years ago.  We had to prepare a nautical chart as one of the projects and it included two compass roses.  I don't recall any particular guidelines though I am sure there are some out there somewhere.  We had to make sure that there were two and they were in locations where they would be of use to the mariner.

    I too have been doing this since I obtained my first GPs, about ten years

    On my Great Lakes Charts once a logical area for the compass rose is
    determined, its placement in the area seems almost random. The center of the
    rose does not seem to "snap" to any major or minor latitude or longitude

    Any ideas of how a cartographer decides the exact location of the roses?
