H3 Resolution Levels

Understanding Multi-Resolution Indexing and Hierarchical Structure in H3

H3 uses a hierarchical system where the world is divided into hexagonal cells at different resolutions, allowing for multi-resolution indexing.

1. Multi-Resolution Indexing (Resolutions 0 to 15)

• Resolution 0: The entire world is divided into 122 base hexagons.
• Higher resolutions (1-15): Each base hexagon is subdivided into smaller hexagons.
• Resolution 15: The smallest possible hexagons.
