rusty-polygon-geohasher
A Rust-backed Python library for geohash operations: converting Shapely polygons to geohash sets, encode/decode, and geography expansion. All compute-heavy paths use Rayon for parallelism.
Originally based on polygon-geohasher (pure Python).
The encode/decode functions are a maintained replacement for pygeohash-fast, which is no longer actively maintained.
Installing
pip install rusty-polygon-geohasher
Usage
Polygon → geohash set
import geohash_polygon
from shapely import geometry
polygon = geometry.Polygon([(-99.1795917, 19.432134), (-99.1656847, 19.429034),
(-99.1776492, 19.414236), (-99.1795917, 19.432134)])
inner = geohash_polygon.polygon_to_geohashes(polygon, precision=7, inner=True)
outer = geohash_polygon.polygon_to_geohashes(polygon, precision=7, inner=False)
Encode / decode
All functions use (lng, lat) order consistently — encode takes (lng, lat) and all decode
functions return (lng, lat, ...).
# Single encode/decode
h = geohash_polygon.encode(lng=-73.554, lat=45.508, precision=7)
lng, lat, lng_err, lat_err = geohash_polygon.decode_exactly(h)
# Batch (parallel via Rayon)
hashes = geohash_polygon.encode_many(lngs=[...], lats=[...], precision=7)
centers = geohash_polygon.decode_many(hashes) # list of (lng, lat)
exact = geohash_polygon.decode_many_exactly(hashes) # list of (lng, lat, lng_err, lat_err)
# Optional thread count
geohash_polygon.encode_many(lngs, lats, 7, num_threads=4)
geohash_polygon.decode_many(hashes, num_threads=4)
geohash_polygon.decode_many_exactly(hashes, num_threads=4)
Expand geohash mappings
Expand each geography's geohash set outward by a given distance in metres. Useful when you want to count or join points-of-interest slightly outside a geography's boundary.
# Single group
expanded = geohash_polygon.expand_geohashes(["f25dvz3", "f25dvz4", ...], expansion_m=500.0)
# Multiple groups — result[i] is the expanded version of groups[i]
groups = [["f25dvz3", "f25dvz4", ...], [...]]
expanded_groups = geohash_polygon.expand_geohash_mapping(groups, expansion_m=500.0)
The hop count is derived from the minimum cell dimension (accounting for latitude-dependent cell width), so expansion is accurate in all directions including east/west at high latitudes. All hashes in a group must have the same precision. Geography expansion runs in parallel across groups.
WKB / EWKB output
Convert geohash bounding boxes to binary WKB or EWKB polygons for direct use
in DuckDB (ST_GeomFromWKB) or PostGIS geometry columns.
hashes = ["f25dvz3", "f25dvz4", ...]
# Plain WKB — 93 bytes per hash
wkb_list = geohash_polygon.decode_many_to_wkb(hashes)
# EWKB with embedded SRID — 97 bytes per hash (default srid=4326)
ewkb_list = geohash_polygon.decode_many_to_ewkb(hashes)
ewkb_list = geohash_polygon.decode_many_to_ewkb(hashes, srid=32632)
# Optional thread count
geohash_polygon.decode_many_to_wkb(hashes, num_threads=4)
geohash_polygon.decode_many_to_ewkb(hashes, num_threads=4)
