Hexagonal hierarchical geospatial indexing system
Hexagonal and easy
H3 offers an easy API for indexing coordinates into a hexagonal grid, down to square meter resolution.
Hierarchical and fast
Indexed data can be quickly joined across disparate datasets and aggregated at different levels of precision.
Algorithms and optimizations
H3 enables a range of algorithms and optimizations based on the grid, including nearest neighbors, shortest path, gradient smoothing, and more.
