panOULU Luotsi: a location based information mash-up with XML aggregator and WiFi positioning

ABSTRACT

We introduce panOULU Luotsi, a multi-device location-based information mash-up provided for the users of a large municipal wireless network. XML content in various forms, such as RSS/ATOM feeds from several content providers are automatically merged into a database using a flexible XML aggregator. It allows mapping different heterogeneous information feeds into the database without any changes to the application source code. The location of the user is estimated by identifying the WiFi access point to which the user's wireless device is currently connected. The information relevant to the user's current location is imposed on a map for a location-based browsing view, which allows the user to learn about nearby services, sites and events of interest.
