Return valid [Geohash](https://en.wikipedia.org/wiki/Geohash) strings representing the position of one or more elements in a sorted set value representing a geospatial index (where elements were added using [`GEOADD`](https://redis.io/docs/latest/commands/geoadd)).

Normally Redis represents positions of elements using a variation of the Geohash
technique where positions are encoded using 52-bit integers. The encoding is
also different compared to the standard because the initial minimum and maximum
coordinates used during the encoding and decoding process are different. This
command returns a standard Geohash in the form of a string as
described in the [Wikipedia article](https://en.wikipedia.org/wiki/Geohash).

## Required arguments

<details open><summary><code>key</code></summary>

The name of the key that holds the geospatial index (a sorted set).

</details>

<details open><summary><code>member [member ...]</code></summary>

One or more members whose Geohash strings to return.

</details>

## Details

### Geohash string properties

The command returns 11 character Geohash strings, so no precision is lost
compared to the Redis internal 52-bit representation. The returned Geohashes
have the following properties:

1. They can be shortened by removing characters from the right. They will lose precision but will still point to the same area.
2. Strings with a similar prefix are nearby, but the contrary is not true, it is possible that strings with different prefixes are nearby too.

## Examples


redis> GEOADD Sicily 13.361389 38.115556 "Palermo" 15.087269 37.502669 "Catania"
(integer) 2
redis> GEOHASH Sicily Palermo Catania

## Return information

**RESP2:**

[Array reply](../../develop/reference/protocol-spec#arrays): an array where each element is the Geohash corresponding to each member name passed as an argument to the command.
