These proceedings include papers presented at the sixth International Symposium on Web & Wireless Geographical Information Systems, held in Hong Kong in December 2006. The symposium aimed to provide an updated review of advances in both theoretical and technical aspects of Web and Wireless Geographical Information Systems (WGIS). This event, part of a series that began in Kyoto in 2001, alternates annually between East Asia and Europe, reflecting the growing community focused on spatially aware geotechnology research. Now recognized as a significant forum, W2GIS has transitioned from a “workshop” to a full 2-day “symposium,” emphasizing quality dissemination and discussion of the latest research and development in the field. The number of submissions highlights the increasing relevance of this area for researchers and its impact on daily life. From over 130 submissions, 72 papers were initially selected for relevance, with 24 papers (33%) chosen for final presentation and inclusion in the proceedings. Each paper underwent a rigorous review process, covering diverse topics such as the Semantic Web, web personalization, contextual representation, mobile environment querying, mobile networks, and recent advancements in location-based services and applications.
