Web and Wireless Geographical Information Systems

2 TheaimoftheannualW GIS workshop is to provide an up-to-date review of advances on recent development of Web and wireless geographical information systems, and new challenges and opportunities for researchers, developers and 2 users in the GIS community. The main topic of the W GIS workshop is theor- ical and technical issues of Web and wireless geographical information systems. This workshop followed the successful 2001, 2002 and 2003 editions, held in - oto, Singapore and Rome, respectively. The 2004 edition was held in Goyang, Korea. 2 In its 4th year, W GIS reached new heights of recognition as a quality wo- shopforthedisseminationanddiscussionofnewwaysofaccessingandanalyzing geospatial information. This year, 39 papers were submitted from 15 countries, and 20 papers were accepted from 11 countries. Similarly, the Program C- mittee consisted of 39 members from 16 countries. We had the privilege of having three distinguished invited talks: Eliciting User Preferences in Web Urban Spaces, Yanwu Yang and Christophe Cla- munt, Naval Academy Research Institute, France; Discovering Regional Inf- mation from Web: Localness and Landmark Computation, Katsumi Tanaka, Department of Social Informatics, Graduate School of Informatics, Kyoto U- versity, Japan; and Towards Knowing, Always and Everywhere, Where - erything Is, Precisely, Christian S. Jensen, Department of Computer Science, Aalborg University, Denmark.
