Clustering based on latitude and longitude in python

Jun 13, 2011 · Note that the original version of this article made a critical mistake – latitude values cannot exceed 90 degrees. While trying to implement my suggestion in a comment to use +-0.0002525254004999719 radians to speed up the query (note, still need to take into account the wrap-around for longitude values) I discovered inconsistent results.
