i meant both but i implemented only transformation from cartesian to
geodetic (XYZ->latitude,longitude,geodetic altitude) and back (which
is trivial)
i can provide source if you need it

distance calc from start(lat,long) to end(lat,long) - this is the
inverse geodetic problem
i also implemented direct geodetic problem:
start(lat,long)+distance+azimuth->end(lat,long)
