geohexgrid 1.1.0

A Python 3.9+ library for making geographic hexagon grids like QGIS’s create grid function. Not designed for making discrete global grid systems like Uber’s H3.

Here’s an example of its main use, namely, minimally covering a GeoDataFrame of features with a flat-top hexagon grid of given resolution.

import geopandas as gpd
import geohexgrid as ghg

# Load New Zealand territorial authorities projected in EPSG 2193 (NZTM)
shapes = gpd.read_file(DATA_DIR / "nz_tas.gpkg")

# Cover it minimally with hexagons of circumradius 10 kilometres
grid = ghg.make_grid(shapes, 10_000, intersect=True)

# Plot
base = shapes.plot(color='red', figsize=(20, 20), aspect="equal")
grid.plot(ax=base, color='white', edgecolor="blue", alpha=0.5)
