Thanks Buckeye, I managed to dig up some info on both the GoogleEarth and FlightGear implementations. Both of which seem to do something very similar to what you have mentioned, essentially breaking it up into 'plates' and working from there. So... |

Thanks for the advice guys!!

Distance to Edge of Circle

You may need to be a little more specific, but if you are just looking for the distance from the edge of the circle to the point then simply do the following.

2/ Grab its length.
3/ Subtract l... |
