A fast geospatial point clustering module.
Project description
A fast Python 3 module for geospatial point clustering.
This is a port of https://github.com/mapbox/supercluster to C++, conveniently wrapped in a Python module. Initial benchmarks show it to be an order of magnitude (10x) faster than the original JavaScript implementation.
Installing pysupercluster
The easiest way to install pysupercluster is to use pip:

Using pysupercluster
>>> import numpy
>>> import pysupercluster
>>> points = numpy.array([
... (2.3522, 48.8566), # paris
... (-0.1278, 51.5074), # london
... (-0.0077, 51.4826), # greenwhich
... ])
>>> index = pysupercluster.SuperCluster(
... points,
... min_zoom=0,
... max_zoom=16,
... radius=40,
... extent=512)
>>> clusters = index.getClusters(
... top_left=(-180, 90),
... bottom_right=(180, -90),
... zoom=4)
[
{'id': 0, 'count': 1, 'expansion_zoom': None, 'latitude': 48.8566, 'longitude': 2.3522},
