We built a back-end database of sharing stations and indexed it with location information using Redis' geospatial data structure. We determined the user's current location through built-in services provided by the operating system, such as CoreLocation on Apple devices. Using the geospatial functions of Redis, we can look up stations within a given distance of our current coordinates, allowing users to find nearby bike-sharing stations and choose a location for their trip. Additionally, Redis provides several other query commands, including GEOPOS, GEODIST, and GEORADIUSBYMEMBER, which can be used to further enhance the location-aware features of an application. These geospatial indexing functions make it easy for developers to add location functionality to their applications.
