Hex Addressing

The AfriHex H3 grid - convert coordinates to human-readable hex codes (AF-GH-7-XXXX) and back, navigate the grid, and render hex map tiles.

📄️Convert coordinates to hex code

Converts lat/lng coordinates to a human-readable hex code (e.g., `AF-GH-7-A3K9`).

Returns the full location details for a hex code.

Returns the ~7 child cells at the next finer resolution.

Returns the 6 neighboring hex cells at the same resolution.

Returns all hex cells within k hops of the origin cell. This is the H3

Returns the hex cell boundary as a GeoJSON Feature for map overlays.

Converts up to 1,000 coordinate pairs to hex codes in a single request.

Resolves a GhanaPostGPS code via the V1 lookup flow, then computes the hex code

Decodes a hex code to coordinates, then reverse geocodes to find the nearest

Returns all hex cells within a bounding box as a GeoJSON FeatureCollection.

Get parent cell at a coarser resolution

Returns the minimum number of hex grid hops between two cells. Both must be at the same resolution.

Returns all cells along the shortest path (inclusive of endpoints). Both cells must be at the same resolution. Maximum 1,000 cells.

Replaces complete sets of child cells with their parent cell. All input cells must be at the same resolution. Maximum 10,000 cells.
