Abstract -- The Taiwan Island is located at the junction of the Philippine Plate and the Eurasian Plate and has frequently been threaten by earthquakes. Furthermore, heavy rainfalls often resulted in floods and debris flows and caused substantial losses in lives and properties and damages to infrastructures.
The goal of this study is to work out a mechanism so information related to natural
hazards can be better utilized in planning and designing infrastructures so damages and/or losses can be minimized with emphasis on selection of routes of, for examples, highways and sites of important facilities.
It is intended to establish a web-GIS based platform to facilitate information sharing so various planners and designer can obtain access to the most-updated information available. This will not only streamline the process and shorten the time required for data collection but also ensure the consistency of information. It will also enable users to utilize the functions provided by GIS software to better comprehend the information given.
