1# Introduction
2
3The **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:
4
5* given a latitude/longitude point, find the index of the containing **H3** cell at a particular resolution
6* given an **H3** index, find the latitude/longitude cell center
7* given an **H3** index, determine the cell boundary in latitude/longitude coordinates
8* and more.

10The **H3 Core Library** is written entirely in *C*. [Bindings for other languages](/docs/community/bindings) are available.
