Aha! You're basing the calculation on the 1791 definition of the metre as being one ten-millionth of the distance from the North Pole to the equator. There's a few things wrong with that:
1. There are 90 degrees in 10 million metres, not 100 degrees. 2. They hadn't measured the distance from the pole to the equator very accurately back in 1791. 3. It only works for great circles anyway. So going North along a meridian is fine, but if you're going East or West along a line of latitude, then it only works at the equator because the circles get smaller as you get nearer the pole. -- http://econym.org.uk/gmap The Blackpool Community Church Javascript Team --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
