Amazon Redshift support for Hexagonal Hierarchical Geospatial Indexing System, H3 for short, offers an easy way to index spatial coordinates into a hexagonal grid, down to a square meter resolution. Indexed data can be quickly joined across different datasets and aggregated at different levels of precision. H3 enables several spatial algorithms and optimizations based on the hexagonal grid, including nearest neighbors, shortest path, gradient smoothing, and more. H3 Indexing and related H3 spatial functions are now available for Amazon Redshift spatial analytics.
