# GEORADIUSBYMEMBER_RO

> Find members within a radius of another member.

<Warning>
  Prefer [`GEOSEARCH`](/docs/redis/commands/geo/geosearch) with `FROMMEMBER` and `BYRADIUS` in new code: `GEOSEARCH <key> FROMMEMBER <member> BYRADIUS <radius> (m | km | ft | mi)`.
</Warning>

Use `GEORADIUSBYMEMBER_RO` to find members within a radius of another member. It is the read-only form of [`GEORADIUSBYMEMBER`](/docs/redis/commands/geo/georadiusbymember).

The center is the stored position of the given member, which always appears among the matches at distance zero. The command accepts the same `WITHCOORD`, `WITHDIST`, `WITHHASH`, `COUNT`, and sorting options but has no `STORE` or `STOREDIST` clause, so it can be served on replicas and used from read-only scripts.

## Syntax

```redis theme={"system"}
GEORADIUSBYMEMBER_RO <key> <member> <radius> (m | km | ft | mi)
  [WITHCOORD]
  [WITHDIST]
  [WITHHASH]
  [COUNT <count> [ANY]]
  [ASC | DESC]
```

## Arguments

| Argument                | Required | Repeatable | Description                                                                                                                |
| ----------------------- | -------- | ---------- | -------------------------------------------------------------------------------------------------------------------------- |
| `<key>`                 | Yes      | No         | Redis key targeted by the command.                                                                                         |
| `<member>`              | Yes      | No         | Member name.                                                                                                               |
| `<radius>`              | Yes      | No         | Search radius, in the unit given after it.                                                                                 |
| `(m \| km \| ft \| mi)` | Yes      | No         | Distance unit: `m` (meters), `km` (kilometers), `ft` (feet), or `mi` (miles).                                              |
| `WITHCOORD`             | No       | No         | Also return the longitude and latitude of each match.                                                                      |
| `WITHDIST`              | No       | No         | Also return the distance from the center, in the requested unit.                                                           |
| `WITHHASH`              | No       | No         | Also return the raw 52-bit geohash score of each match.                                                                    |
| `COUNT <count> [ANY]`   | No       | No         | Return at most `<count>` matches. `ANY` returns as soon as enough matches are found, instead of sorting every match first. |
| `(ASC \| DESC)`         | No       | No         | Sort the matches by distance from the center: `ASC` (nearest first) or `DESC` (farthest first). Unsorted when omitted.     |

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply                                                |
| -------- | ---------------------------------------------------- |
| RESP2    | Array of bulk-string members or member-detail arrays |
| RESP3    | Array of bulk-string members or member-detail arrays |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
</Note>

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
