I've been developing a little gps app which I have linked off my web page
in source form:
http://mgorse.dhs.org/software/landmark/
I originally intended for it to run under Linux, but it can also be built
under Windows through mingw, although I haven't takent he time to document
the process to create a mingw binary.
Anyway, to get to the point, it has functions to calculate distances and
angles, although I'm not even sure what algorithm it uses to calculate
distances; I only lifted the code from gpsdrive. It uses simple trig to
calculate angles, trying to compensate for curvature depending on initial
coordinates, although this would be inaccurate for large distances.
