H3 indexes points and shapes into a hexagonal grid.

---------------------------------------------------------------------

H3 is a discrete global grid system for indexing geographies into a
hexagonal grid, developed at Uber.

Coordinates can be indexed to cell IDs that each represent a unique
cell.

Indexed data can be quickly joined across disparate datasets and
aggregated at different levels of precision.

H3 enables a range of algorithms and optimizations based on the grid,
including nearest neighbors, shortest path, gradient smoothing, and
more.
