Geohash

Geohash is a system for encoding geographic coordinates (latitude and longitude) into a compact string of characters. It was invented by Gustavo Niemeyer in 2008 and is often used in geospatial applications to simplify location-based data handling and storage. ### How it Works: 1. **Encoding**: A geographic location is represented by dividing the Earth into a grid of cells. Each cell is given a unique identifier (the "Geohash") made up of a string of letters and numbers.
