A library for geohash encoding, decoding and associated functions
Project description
Geolib
A python library for geohash encoding, decoding and finding neighbour cells. This is a python port of Chris Veness' javascript implementation.
Installation
pipenv install geolib
or
pip install geolib
Usage
from geolib import geohash
Encode a latitude, longtiude to geohash
geohash.encode(latitude, longitude, precision)
>>> geohash.encode('70.2995', '-27.9993', 7)
>>> gkkpfve
Decode a geohash to latitude, longitude
geohash.decode(geohash), returns latitude, longitude as tuple of decimals
>>> geohash.decode('gkkpfve')
>>> (70.2995, -27.9993)
Find neighbouring cells of a geohash
geohash.neighbours(geohash)
retuns a namedtuple (n, ne, e, se, s, sw, w, nw)
>>> neighbours = geohash.neighbours('gcpuyph')
>>> neighbours
>>> ('gcpuypk', 'gcpuypm', 'gcpuypj', 'gcpuynv', 'gcpuynu', 'gcpuyng', 'gcpuyp5', 'gcpuyp7')
>>> neighbours.ne
>>> gcpuypm
Find adjacent cell in a given direction
geohash.adjacent(geohash, direction)
>>> geohash.adjacent('gcpuyph', 'n')
>>> gcpuypk
Find SW/NE latitude/longitude bounds of a geohash
geohash.bounds(geohash)
returns a namedtuple ((sw_lat, sw_lon), ((ne_lat, ne_lon))
>>> bounds = geohash.bounds('ezs42')
>>> bounds
>>> ((42.583, -5.625), (42.627, -5.58)))
>>> bounds.sw.lat
>>> 42.583
