#geodist(key, member1, member2, unit = 'm') ⇒ String?

Returns the distance between two members of a geospatial index

Parameters:

  • key (String)
  • members (Array<String>)
  • unit ('m', 'km', 'mi', 'ft') (defaults to: 'm')

Returns:

  • (String, nil) —

    returns distance in spefied unit if both members present, nil otherwise.

#geohash(key, member) ⇒ Array<String, nil>

Returns geohash string representing position for specified members of the specified key.

Parameters:

  • key (String)
  • member (String, Array<String>) —

    one member or array of members

Returns:

#georadius(*args, **geoptions) ⇒ Array<String>

Query a sorted set representing a geospatial index to fetch members matching a given maximum distance from a point

Parameters:

  • args (Array) —

    key, longitude, latitude, radius, unit(m|km|ft|mi)

  • sort ('asc', 'desc') —

    sort returned items from the nearest to the farthest or the farthest to the nearest relative to the center

  • count (Integer) —

    limit the results to the first N matching items

  • options ('WITHDIST', 'WITHCOORD', 'WITHHASH') —

    to return additional information

Returns:

  • (Array<String>) —

    may be changed with options
