Find all the geo position members saved in a geoindex, which are within a certain distance and in a certain area(circular or box). This command can be used as a substitute for GEORADIUS and GEOREDIUSBYMEMBER commands, as those commands are deprecated.
Get the longitude and latitude of specific members from a geospatial index. Multiple members are allowed in the same command, so we can get the position of multiple members at the same time as an array.
Get the geohash string for one or more geo index members. We can add some members(longitude, latitude, member_name) to a geoindex using “GEOADD” command, then we can get the geohash of those members using this GEOHASH command.
Get the distance between 2 members/items saved in geospatial index. Geospatial information is saved in a sorted set data structure, when added with GEOADD command. This GEODIST command helps us to get the distance between 2 members saved in the geoindex.
