# rxGeoradiusbymember

`open fun rxGeoradiusbymember(key: String, member: String, radius: Double, unit: GeoUnit): Single<String>`

This command is exactly like 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.

### Parameters

`key` - Key string

`member` - member

`radius` - radius

`unit` - geo unit

Return
