rFocus provides a handful of GIS-related web services to the public free of charge. These are limited in focus, designed mainly to showcase some of the technologies that rFocus has been involved in. They are also available as a resource for anyone who only requires simple geolocation services. The GIS APIs allow users to find the real-world locations of IP addresses, get the GPS locations of physical addresses, perform reverse geocoding, retrieve location-related Wikipedia articles, get the weather for a given location, and track courier packages.
