Geohash Spatial Index
Technical Details & Mathematical Formulation
Created by Gustavo Niemeyer in 2008. The algorithm alternates interleaving binary bits of latitude and longitude, subdividing the globe recursively. A key feature is prefix locality: points sharing a common Geohash prefix lie within the same rectangular spatial cell.
