Re: Plotting a great circle distance

Hi RAF,

thanks for the response.

I guess in essence what I was trying to do, was determine how to
determine the projection path between two points - as you correctly
rephrased it.

I believe the Mercator projection tends to be the projection used in
the Airline industry? Doing a quick search on Google I come across the
following link;

http://en.wikipedia.org/wiki/Mercator_projection

My understanding would be, for a Mercator projection the first set of
projections would be used.

Thus for the point Longitude 20 Lat 30 , the mercator projection would
be x = 20, y= 32.7404?

cheers

.
