The H3 geospatial indexing system is a multi-precision hexagonal tiling of the sphere indexed with hierarchical linear indexes. The H3 Core Library provides functions for converting between latitude/longitude coordinates and H3 geospatial indexes. Specifically, the major library entry point functions (defined in
h3api.h) provide the functionality:
The H3 Core Library is written entirely in C. Bindings for other languages are available.
