Introduction
GEO
Geo is a feature introduced in Redis version 3.2.
You enter longitude (vertical line) and latitude (horizontal line) of two points/cities
and compute the distance between them.
Redis Geo assumes the Earth is a perfect sphere.
Therefore an error of about 0.5% can occur in the worst case.
Geo uses the Sorted Set data structure. So some commands can be used as Sorted Set commands.
Range query: ZRANGE key 0 -1, delete: ZREM key member, count: ZCARD key
