GeoBike is a Redis-based bike share application that uses publicly available data from various sharing systems to demonstrate the geospatial features of Redis. It incorporates data from CitiBike Bikeshare in New York City, using their General Bikeshare Feed specification. The application loads information about bike sharing stations into Redis, including location and optional fields such as cross-street or accepted payment methods. To handle updates, GeoBike iterates over the set of station data loaded into memory, removes it from the geospatial indexes and deletes it from the list of stations for the system. The application uses Redis hashes to store variable station information and Sorted Sets to build a geospatial index for searching stations relative to some coordinates. GeoBike also notifies clients relying on its data using the Redis Pub/Sub mechanism.
