    Re: Great Circle Initial Course Boston to Wellington?

    Sean,

    My analogous spreadsheets (attached) agree with yours on the locations of the waypoints. There are differences in the courses and distances for the individual segments between the waypoints; I’m pretty sure it’s because your spreadsheet uses (I believe) great-circle formulae, whereas mine refers to rhumb lines.
