altitude distance longitude

Dear sirs,

just one question:

given two points whose spherical coordinates are:

A (Long1, Lat1, Alt1) and B (Long2, Lat2, Alt2)

Do you know the formula to konw the distance AB?

Thanks in advance,

Lupin

Hi

this may help

If this doesn't help search for converting the sphere map dimensions into flat map dimensions and after that use the normal geometry after transformations
D=√((Long1-Long2)2+(Lat1-Lat2)2+(Alt1-Alt2)2)

Added after 7 minutes:

the previous suggestion is valid if you mean converting distance over the earth
but If you mean real spherical co-ordinates so it's not long, lat & alt
they are r ,θ &Φ
