What are Geohash coordinates?

Geohashing 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 geohash location?

A geohash is a convenient way of expressing a location (anywhere in the world) using a short alphanumeric string, with greater precision obtained with longer strings. Geohash. Enter latitude, longitude & precision to obtain geohash; enter geohash to obtain latitude/longitude.

How is geohash calculated?

From the GPS coordinates, the geohash is calculated by creating two binary strings, one for the longitude and one for the latitude, by dichotomy of the corresponding intervals. By splitting each interval into 2 equal parts and noting 0 the left interval and 1 the right interval.

What is geohash value?

A 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.

What is geohash length?

High precision geohashes have a long string length and represent cells that cover only a small area. Low precision geohashes have a short string length and represent cells that each cover a large area.

What is geohash used for?

Geohashing 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.

Why is geohash useful?

Transitland uses geohashes as a prime component of Onestop IDs, our system for creating stable identifiers for public transit operators, routes, and stops. The short length and arbitrary precision of geohashes are extremely useful for approximately geolocating millions of transportation locations.

How many geohashes are there?

As shown in the figure the world is divided into 32 geohashes of level-1 having area 5000×5000 kmsq. and if we go to geohash level 2 the cells are further divided into 32 parts each of area 1250×625 kmsq.
