A5

Global, equal-area, millimeter-accurate geospatial index

INTRODUCTIONEXAMPLES

Pentagonal Discrete Global Grid System

A5 is a global geospatial index. It is the pentagonal equivalent of other DGGSs, like S2 or H3, but with higher accuracy and lower distortion.

Flexible representation of geospatial data

A5 is used for representing points, lines, and polygons in a unified cell format, which is well suited for combining datasets and aggregating data.

Uniform Cell Sizes with Minimal Distortion

Data from all around the world can be directly compared due to the practically equal areas of all A5 cells.
