    Re: latitude and longitude with Yeoman Chart Plotter
    From: Glendon

    Hmm, interesting. I had not realised that Yeoman required the three points
    to make a right angle on lat/lon. The only demonstration of one that I have
    seen (at a boatshow), glossed over that. Other mapping software that I am
    familiar with, such as OziExplorer, will georeference a linear graduated map
    on any three points, with accuracy of calibration improved if the three
    points are chosen somewhat as described below as necessary for the Yeoman.
    Referencing a curvilinear graduated map on such software requiring 7 or more
    points
