The recent advances on the developments of Wireless and Internet technologies have generated increasing interest in the diffusion and processing of geo-referenced data. Wireless and Internet devices also offer new ways of accessing and analyzing geo-spatial information. Consequently, new challenges and opportunities have been provided to the GIS research community.

This Symposium is intended to provide an up-to-date review of advances in recent development of Web and Wireless Geographical Information Systems (W²GIS). It is the 15th in a series of successful events beginning with Kyoto 2001, and mostly alternating locations between East Asia and Europe, with the most recent event held in Grenoble, France. We invite submissions that address both theoretical and technical issues of W²GIS. Reports on implementations are particularly welcome. Suggested topics include, but are not limited to as long as they address issues related to W²GIS and location-based services:

• Geospatial databases and spatio-temporal data management
• Mobile spatial interaction
• Spatial search, GeoWeb search engines and services
• Spatially embedded social networks and the Web
• On-line spatial data mining
• GeoSensor data acquisition, processing, management and analysis
• Smart environments, Internet of Things and ambient spatial intelligence
• Exploratory cartography and Web and wireless geo interfaces
• Advanced GIS visualization techniques for Web and mobile applications
• Cyber-geography & augmented reality
• Map personalization and adaptation
• 3D modelling of cityscapes for location-based services
• Location-based service applications in both real-world and virtual spaces
• Ubiquitous and wireless GIS
• Security, privacy, and usability issues of Web and wireless environments
• Semantic geospatial Web and interoperability
• Telematics and GIS applications
• User studies and evaluations of online geo services
• Indoor and outdoor wayfinding and navigation
• Volunteered Geographic Information and crowdsourcing on the Web
