@WeatherGod You are totally correct. The last dataset on which I have needed to do this was an unprojected grid with a constant increment of 0.5 degrees between points, so finding nearest neighbors was easy.

If you have a lot of points to select at, finding nearest neighbor points could be done efficiently with a tree, e.g., scipy.spatial.cKDTree: http://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.KDTree.query.html#scipy.spatial.KDTree.query
