rusty-polygon-geohasher

Polygon Geohasher is an open source Python package for converting Shapely's polygons into a set of geohashes. It obtains the set of geohashes inside a polygon or geohashes that touch (intersect) the polygon.

The library is based on the polygon-geohasher library which is implemented in pure python. The main difference is that this library is implemented in Rust, yielding a significant performance improvement.

Installing

You can get the library from the Python Package Index (PyPI) using pip:

$ pip install rusty-polygon-geohasher

Usage

Here are some simple examples:

from polygon_geohasher.polygon_geohasher import polygon_to_geohashes
from shapely import geometry

polygon = geometry.Polygon([(-99.1795917, 19.432134), (-99.1656847, 19.429034),
                            (-99.1776492, 19.414236), (-99.1795917, 19.432134)])
inner_geohashes_polygon = geohash_polygon.polygon_to_geohashes(polygon, 7, inner=True)
outer_geohashes_polygon = geohash_polygon.polygon_to_geohashes(polygon, 7, inner=False)
