Abstract: Abstract of thesis entitled An Evaluation of 3D-GIS as a Public Engagement Tool in Environmental Impact Assessment Submitted by Kwong Kim Hung for the Degree of Master of Philosophy at the University of Hong Kong in July 2006 Three-Dimensional (3D) GIS have been employed to engage the public in the Hong Kong EIA process in recent years. However, knowledge on the effectiveness of using 3D GIS in public participation of the EIA process is relatively limited, especially in the Hong Kong context. This research investigated the effectiveness of an existing 3D GIS in facilitating the public participatory process of Hong Kong EIA and ascertained merits and deficiencies of this tool. The research was based on a study by Lai et al. (2005) who employed GIS in the creation of 3D visualizations to document EIA results of Central and Wan Chai reclamation projects. It focused on assessing the ability of visual systems in conveying EIA information to the public and the public's perceptions towards the systems interface, given that the ability to educate people is regarded as one basic function for public participation. An online questionnaire survey was conducted to study the public's attitudes towards the interface, functionality and ease of use of an existing 3D GIS in EIA. 3D visualizations were compared to conventional planimetric maps to examine if they were more effective in delivering EIA information to the public. Quantitative data and qualitative comments were collected from the survey. It was found that participants of the survey rated planimetric maps as easier to use and more preferable for the presentation of EIA information. However, 3D visualizations seemed more captivating and invigorating. Given the complementary and supplementary roles of the two means of display, it was recommended that both display methods should be employed in conveying EIA information to provide a comprehensive coverage. It is hoped that this study can contribute toward building a more interactive and continuous GIS driven public participation process for EIA in Hong Kong which is important in moderating possible conflicts and misunderstandings in pursuit of sustainable development. The research methodology expects to provide a foundation for similar research in the future.
