Geohash base32

WebI would like to know the precision of a Geohash with a given length. If there is a 'simple' formula you can use to calculate it, that would be extra-cool. Wikipedia lists the precision up to 8 characters: # km 1 ±2500 2 ±630 3 ±78 4 ±20 5 ±2.4 6 ±0.61 7 ±0.076 8 ±0.019. length. WebMost geohash libraries these days have geohash integer functions built in, and you'll need to use these instead of the more common base32 geohashes. Based on the radius you …

WebA point can be expressed as a geohash. Geohashes are base32 encoded strings of the bits of the latitude and longitude interleaved. Each character in a geohash adds additional 5 bits to the precision. So the longer the hash, the more precise it is. For the indexing purposed geohashs are translated into latitude-longitude pairs.
