code to convert 3D geographical coordinates to Cartesian?
...some package
(of which I'm currently unaware) has already coded this The Right Way.
For now, for the atmospheric model with which I need to work, I
believe I can just assume a spherical earth with r=6370 km, and just
add that to the elevation.
3. composition of the two (e.g., sph2cart(geo2sph(lat.lon.elev))),
noting that package=pracma uses the mathematics convention that
azimuth=? and polar angle=? (vs the reverse physics convention).
Net: the task seems straightforward enough, but there's certainly scope
for error, so I'd prefer to use tested, well-used code if availabl...
