An open-source hierarchical hexagonal grid system developed by Uber for partitioning the Earth’s surface into cells of varying resolution widely used in geospatial analytics for aggregating mobility data.
Because every cell at a given resolution is roughly the same size and shape, H3 avoids the distortion you get from squares or from irregular administrative boundaries making it easier to aggregate mobility signals consistently whether you’re looking at a single city block or an entire country, simply by choosing a coarser or finer resolution.
