Experiment with the Vicenty formula on the ellipsoid to calculate the distance #2

Closed jsanz closed 10 years ago

According to the wikipedia entry we can use the Vicenty Formula, but we need to double check as it happens that the antipodal distance is the hardest use case where the iterations cannot converge.

JavaScript source code available here.

Tried and as expected, the formula doesn't converge for antipodal distance. I've left it for city to center of the view calculation. (1h)
