Pygeohash-Fast
A Fast geohasher for python.
Created by wrapping the rust geohash crate with pyo3.
Huge shout out to the georust community :)
Currently very WIP, only supports encoding geohashes.
Speed Comparisons
Compared against the great python library pygeohash This isn't a perfect benchmark, but should illstrate what's possible. Tested on 1 million randomly generated lat/long pairs.
Results for Pygeohash
In [14]: %%timeit
...: [encode(lats[i], lngs[i], 8) for i in range(len(lats))]
10.8 s ± 77.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
Results for Pygeohash-fast encode:
In [16]: %%timeit
...: [fast_encode(lngs[i], lats[i], 8) for i in range(len(lats))]
3.44 s ± 11.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
However, in order to improve things in further when encoding many points we have methods for encoding many points at once.
In [22]: %%timeit
...: encode_many(lngs, lats, 8)
155 ms ± 3.58 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)
So for simple geohash encoding this library is ~69x times faster, nice.
