Geodetic calculations

[Alex]

Hi everybody

I need to do geodetic calculations in Turbo Pascal 6. From two geodetic
coorinates (WGS84) I want to calc heading (direction) and distance.

Can anybody help me ?

Google is your friend here. Try searching "vincenty" He wrote the
definitive paper on this. You need his "direct solution". A quick look
found this:

math at bottom. The headings are not available in the online applet but
are in the math. If you need help contact me at victorf ATSIGN
windreader DOT com. I have done this in Pascal (Delphi). There is no
reason why it can't be done in TP. I have transcribed Vincenty's
original paper also.

You need to indicate whether by Great Circle or by Rhumb Line or both,
unless the distances are trivial or the directions N / S.
