    Gnomonic charts and distances
    From: Bob Goethe
    Date: 2018 Jan 22, 11:07 -0800

    Is a great circle course, as laid out on a gnomonic chart, useful in determining distances?

    For instance, if I draw a line on a gnomonic chart from Vancouver to London, can I measure half way along that line and say "That is indeed the half-way point in a journey that follows this course-line"?

    Thanks!

    Bob
