> [!NOTE]
> This command's behavior varies in clustered Redis environments. See the [multi-key operations](https://redis.io/docs/latest/develop/using-commands/multi-key-operations) page for more information.
This command is exactly like [`GEORADIUS`](https://redis.io/docs/latest/commands/georadius) with the sole difference that instead
of taking, as the center of the area to query, a longitude and latitude value, it takes the name of a member already existing inside the geospatial index represented by the sorted set.
The position of the specified member is used as the center of the query.
Please check the example below and the [`GEORADIUS`](https://redis.io/docs/latest/commands/georadius) documentation for more information about the command and its options.
Note that [`GEORADIUSBYMEMBER_RO`](https://redis.io/docs/latest/commands/georadiusbymember_ro) is also available since Redis 3.2.10 and Redis 4.0.0 in order to provide a read-only command that can be used in replicas. See the [`GEORADIUS`](https://redis.io/docs/latest/commands/georadius) page for more information.
## Required arguments
key
The name of the key that holds the geospatial index (a sorted set).
member
The member whose position is used as the center of the search.
radius
The radius of the search circle, in the unit given by the following argument.
M | KM | FT | MI
The unit for `radius`: meters (`M`), kilometers (`KM`), feet (`FT`), or miles (`MI`).
WITHCOORD
Also return the longitude and latitude of each matching item.
WITHDIST
Also return the distance of each matching item from the center, in the same unit as the radius.
WITHHASH
Also return the raw 52-bit geohash-encoded score of each matching item.
COUNT count [ANY]
Return at most `count` matches. With `ANY`, the command returns as soon as enough matches are found — faster, but the results may be unsorted.
ASC | DESC
Sort the results by distance from the center: nearest first (`ASC`) or farthest first (`DESC`).
STORE key
Store the results as a geospatial index in `key` instead of returning them. `STORE` and `STOREDIST` are mutually exclusive.
STOREDIST key
Store the results in `key` as a sorted set of distances from the center, instead of returning them.

## Return information
**RESP2:**
One of the following:
* If no `WITH*` option is specified, an [Array reply](../../develop/reference/protocol-spec#arrays) of matched member names
* If `WITHCOORD`, `WITHDIST`, or `WITHHASH` options are specified, the command returns an [Array reply](../../develop/reference/protocol-spec#arrays) of arrays, where each sub-array represents a single item:
* The distance from the center as a floating point number, in the same unit specified in the radius.
* The Geohash integer.
* The coordinates as a two items x,y array (longitude,latitude).
