The role of GI-supported methods in crisis management

Crisis and disaster management has become an important research field in GIS during recent years. Risk assessment and situation picture-related work are particularly important areas of interest. There are distinct phases in different crises; these can be roughly divided into mitigation, preparedness, response, and recovery. In this paper a general classification of methods in each phase is given with examples on recent or ongoing research projects. The framework is based on literature and experiences from crisis and disaster-related exercises. Three case studies are based on those exercises. The goal is to clarify the role and usability of various GI-supported methods in the crisis management process by outlining a theoretical framework and presenting examples of the developed methods. Continuously increasing amount of spatially related geographic information is a huge potential to the GI analysis and modeling methods; the concept of digital earth is the underlying mainstream that gives lots of promise to the research and development work in this field.
