Case Studies of a WebGIS System for Disaster Risk Management in Japan and its Applicability with Alert Information in Malaysia

Abstract:
Many landslide and flood disasters occur during rainy seasons every year in various parts of the world. To reduce the damage caused, disaster risk information as exemplified by hazard maps or risk maps is important for local government and local communities. On the other hand, these maps do not show that the intense distribution of rainfall varies with time. This means that the hazard area changes dynamically with time. Therefore, risk management for landslides and flood disasters requires dynamic warning information.
Geographic Information Systems (GIS) are an essential technology for supporting the various phases of risk management. In particular, WebGIS can directly integrate various types of disaster risk information including dynamic warnings on the Internet and provide an easy way for all people to access disaster risk information. E-Community Map, which has been developed as open source software based on WebGIS technologies, integrates geospatial data provided through interoperable data interfaces of various distributors. Users can input their own information using PCs, GPS-equipped phones, and other tools. The system can output various maps, including online dynamic maps and printed maps for off-line communication and field surveys. These maps and the mapping process are effective for understanding local environments and taking decisive action. Users can compare and overlay various geospatial data and understand hazards and risks corresponding to the data. Then, they can check points of interest and input various data, photos, and memos, and can examine the adequacy of preparations and cooperate with stakeholders. Finally, they can make their own maps and maintain them through participation. The maps can be for individual, family, or community use and can help improve preparedness.
The Japan Science and Technology Agency (JSTA) launched a project entitled “Research and Development for Reducing Geo-Hazard Damage in Malaysia Caused by Landslide and Flood” in 2010. We are adapting and improving e-Community Map for this project. In this paper, we introduce case studies using this system in Japan and discuss its potential application in Malaysia.
