Hello,
I am using -
https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.KDTree.html#scipy.spatial.KDTree
which I believe is using Euclidean distances underneath the hood. But I
want to be able to use great circle distances. Is this the only way to do
this -
https://stackoverflow.com/questions/20654918/python-how-to-speed-up-calculation-of-distances-between-cities
or is there some way I can extend that class to use great circle
distances(maybe somebody has already done that ? ) I have a irregular
shaped grid in a WGS 84 ellipsoid(can be assumed to be a sphere) and so I
want to use great circle distances or if somebody can convince me not to
that would be great as well.
Best regards,
Ashwin.
