Over-Talk Posted December 16, 2008 Report Share Posted December 16, 2008 Nice variety of answers......but completely useless. Please re-read his question......he is not asking about great circles or rhumb lines. Think of the question this way....to go the shortest distance, direct from Toronto to Bangkok, you would need to pass through the center of the planet Earth. Is this the distance that the satellites calculate ?? My answer is NO......you won't need a very large drill rig to get to Bangkok if you use a GPS!! I suspect the satellites are programmed to think of the Earth as a large flat surface, not a round object. Now that we have that sorted, you guys can go back to discussing Great Circles over a flat surface, transverse mercators etc etc. Remember that 212 Wrench is a teacher by trade, and is often more interested in how you answer the question, rather than what you answer. How did I do Wrench? Did I earn a University Degree, so that I can learn to fly a 407 around Niagara Falls? Quote Link to comment Share on other sites More sharing options...
