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 geo hashing?
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. For a given location on earth, the Geohash algorithm converts its latitude and longitude into a string.
How do you decode coordinates?
When outlining the coordinates of a location, the line of latitude is always given first followed by the line of longitude. Therefore, the coordinates of this location will be: 10°N latitude, 70°W longitude. The line of latitude is read as 41 degrees (41°), 24 minutes (24′), 12.2 seconds (12.2”) north.
How big is a geohash?
Cell dimensions at the equatoredit
| GeoHash length | Area width x height |
|---|---|
| 5 | 4.9km x 4.9km |
| 6 | 1.2km x 609.4m |
| 7 | 152.9m x 152.4m |
| 8 | 38.2m x 19m |
What is the use of geohash?
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. Enter latitude, longitude & precision to obtain geohash; enter geohash to obtain latitude/longitude.
How do I find geographic coordinates for an address?
Get the coordinates of a place
- On your computer, open Google Maps.
- Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top.
- To copy the coordinates automatically, left click on the latitude and longitude.
What are the different GPS coordinate formats?
The three common formats:
| DDD° MM’ SS.S” | Degrees, Minutes and Seconds |
|---|---|
| DDD° MM.MMM’ | Degrees and Decimal Minutes |
| DDD.DDDDD° | Decimal Degrees |
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.
What is latitude format?
When writing latitude and longitude, write latitude first, followed by a comma, and then longitude. For example, the above lines of latitude and longitude would be written as “15°N, 30°E.”
