geohashlite 0.3.2

A python library for interacting with geohash

Geohash Lite

GeohashLite is a Python package for dealing with GeoHash code. It support also conversion between GeoJSON and a list of GeoHash.

Installation

Clone this repository

git clone https://github.com/qxzzxq/python-geohash.git

Then install with python

cd python-geohash
python setup.py install

Dependencies

Shapely

Usage

Coordinates encoding

import geohashlite
geohashlite.encode(48.86913, 2.32275, 7)

Geohash decoding

geohashlite.decode('u09whb7')

Conversion between GeoJSON and GeoHash

# GeoHash to GeoJSON
converter_1 = geohashlite.GeoJsonHasher()
x = ['u09k', 'u095', 'u08g', 'u09h', 'u09e', 'u097']
converter_1.geohash_codes = x
converter_1.decode_geohash(multipolygon=True)
print(converter_1.geojson)


# GeoJSON to GeoHash
converter_2 = geohashlite.GeoJsonHasher()
fc = {
  "type": "FeatureCollection",
  "features": [
    "GeoJSON_Feature",
  ]
}
converter_2.geojson = fc
converter_2.encode_geojson(precision=4)
print(converter_2.geohash_codes)

Convert a geohash list to geojson (deprecated)

geohashlite.geohash_2_geojson(['u09whb7'])

Convert geojson to a geohash list (deprecated)

fc = {
  "type": "FeatureCollection",
  "features": [
    "a_GeoJSON_Feature"
  ]
}

geohashlite.geojson_2_geohash(fc, precision=7)
