H3 can be difficult to use in tradition GIS workflows. Here are some utility functions to help with this.
pip install git+https://github.com/sabman/h3-utils.git@main#egg=h3_utils
Find resolution for a given cell find_cells_for_geojson
form h3_utils import tools as h3_tools
cells, resolution = h3_tools.find_cells_for_geojson(geoJson, 6)
print("=============================================")
print("found cells:", cells)
print("found resolution:", resolution)
print("---------------------------------------------")
# if the returned cell is not the resolution we want, we can find the resolution by finding the parent cells of the found cell
if resolution > 6:
print("\nlooking for parent cells of the found cell...\n")
cells = h3.h3_to_parent(list(cells)[0], 6)
print("🎉 required cells:", cells)
print("🎉 required resolution:", 6)
print("=============================================")# =============================================
# found cells: {'89b91695833ffff'}
# found resolution: 9
# ---------------------------------------------
# looking for parent cells of the found cell...
# 🎉 required cells: 86b91695fffffff
# 🎉 required resolution: 6
# =============================================Here is the cell visualized visualize_geojson_enclosing_cell(geo_json, resolution).
find the cells for a given geojson and coverage level using find_resolution_for_geojson(geo_json, coverage_level).
