WebA Geohash is a unique identifier of a specific region on the Earth. The basic idea is that the Earth is divided into regions of user-defined size and each region is assigned a unique id, which is called its Geohash. For a given location on earth, the Geohash algorithm converts its latitude and longitude into a string. WebArguments¶. Required: geohash. The argument must be a geohash. Optional: precision. The number of characters to use from the input geohash. For example, passing 5 for precision causes the function to use the first 5 characters in the geohash.. You can specify a value from 1 to 20..
