In this paper we describe a multichannel, mobile, and location-based application called GeoPix developed as a proof-of-concept for several use cases related to eTourism. In GeoPix, mobile users produce geo-referenced pictures and share them with Web users that can access the online database with a smart navigation experience based on maps. Web users can browse, pan, zoom areas immediately seeing the pictures posted by the on-the-road users. Thumbnails are directly overlaid on the maps exactly where the full-size photos are taken. They can also make searches, apply filters, and save geographic bookmarks of the photos displayed on the maps. In this way a large database of images can be easily browsed in a way that we call geo-browsing.
