H3 cell tools

Encode and decode H3 indexes, explore hexagonal cells, cover shapes and convert spatial data.

Decode

Convert an H3 cell to coordinates, check its GeoJSON or WKT representation, visualize it in a map and much more

Encode

Convert a pair of latitude, longitude coordinates to its H3 cell representation at any precision

Draw

Bring your CSV H3-encoded data to visualize it on a map

Aggregate

Bring your coordinate-encoded CSV dataset to aggregate it by H3 cells

Browse

What is H3?

H3 is a global discrete hexagonal grid system that divides the Earth's surface into a series of hexagons of varying sizes.

Developed at Uber, H3 has resolutions from 0 to 15. Its hierarchy supports spatial indexing, neighbor queries and data aggregation.
