WebGeohashing (or geohash) is a geocoding method used to encode geographic coordinates (latitude and longitude) into a short string of digits and letters delineating an area on a map, which is called a cell, with varying resolutions. The more characters in the string, the more precise the location. What is an example of a geohash? Geohash is a public domain of … WebMar 11, 2024 · Geohash can be a useful geospatial clustering tool. Geohash has 18 accuracy levels with area coverage ranging from 25 Million km² at the highest level 1 to 0.6 μ² at the lowest level 18. Common prefixes of geohash indicate proximity of points to each other. The longer a shared prefix is, the closer the two places are.
