Abstract To Improve a Public Participation Decision Support System Track: Application Development Author(s): Seho Park, Yunsoo Choi, Jiyeong Lee, Jung Yeol Nam Despite the importance of the public participation process, there are methods lacking to support the participation. Web-based technologies have been developed to overcome above the obstacles. Web 2.0 resolves the problems, which allows people to share their opinions. Although the Web 2.0 technology allows users to participate in the planning process easily, the web-based Public Participation GIS (PPGIS) requires another tool to collect and manage user's opinions. The opinions would be submitted in different formats. For example, it is reported by using images and movies or text formats. However, the PPGIS should produce collective and overall summarized information from the public input data in order to support decision makers. Therefore, the purposes of this research are to develop 1) a spatial data warehouse using ArcIMS and .NET Application based on ArcServer, 2) Easy-to-use Web environment using AJAX, and 3) XML-based tools to organize and reclassify various formatted opinions in order to efficiently analyze the data Seho Park Geoinformatics, University of Seoul Adormistory 716, University of Seoul 90 Jeonnong-dong Dongdaemun-Gu Seoul , Seoul 130-743 Korea, South Phone: 0820222105072 E-mail: gulex3@gmail.com Yunsoo Choi Geoinformatics, University of Seoul 21C Building 517, University of Seoul 90 Jeonnong-dong Dongdaemun-gu Seoul , Seoul 130-743 Korea, South Phone: 0820222102430 E-mail: choiys@uos.ac.kr Jiyeong Lee Geoinformatics, University of Seoul Jeonnong Building 116, University of Seoul 90 Jeonnong-dong Dongdaemun-gu Seoul , Seoul 130-743 Korea, South Phone: 0820222105750 E-mail: jlee@uos.ac.kr Jung Yeol Nam Facilities Management Division 0ffice of Waterworks Seoul Metropolitan Government.
