A5 cell tools

Encode and decode A5 indexes, explore cells on a map, cover shapes and convert spatial data.

Decode

Convert an A5 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 A5 cell representation at any precision

Draw

Bring your CSV A5-encoded data to visualize it on a map

Aggregate

Bring your coordinate-encoded CSV dataset to aggregate it by A5 cells

Browse

What is A5?

A5 divides the Earth into equal-area pentagonal cells based on a dodecahedron.

A5 uses 64-bit cell identifiers and 31 resolutions, from 0 to 30. Hexadecimal tokens identify cells for spatial indexing, region coverings, neighbor queries and data aggregation.
