Description

In 1997, Cartography and Geographic Information Systems published a special issue on "GIS and Environmental Risk Assessment" which primarily focused on topics related to environmental health. Since that time, interest in mapping hazards has expanded both conceptually and methodologically. Events such as the 2004 tsunami, Hurricane Katrina, the Sichuan earthquake, and the Southern California wildfires demonstrate the need for continued investigation of hazards and disasters, especially studies that help us understand the multivariate spatial relationships that exist in these post-disaster environments. How can cartography, Geographic Information Systems (GIS), geotechnologies, and spatial analysis contribute to the generation of this knowledge? This special issue of CaGIS provides several examples of how geographers and other spatial scientists are approaching these challenges. In particular, authors were asked to focus on gaps in research regarding the temporal and spatial scales at which hazards and disasters are studied, and the issue of communicating knowledge of these events through spatial data. Hazards and disasters are commonly studied at city or county scales, but processes related to preparedness, response, recovery, and mitigation occur at a finer-scale geography, such as the neighborhood or sub-neighborhood levels. Many of the papers address data collection and analytical approaches at these finer scales, including both the limitations and benefits of this move toward micro-geographies. In addition, most existing studies of extreme events have a limited time frame for monitoring long-term recovery (often only one to two years) even though current research suggests that the effects of exposure are spread over a longer time frame. In response to this phenomenon, articles were requested which address mapping and strategies for collecting temporally dynamic spatial data and which focus on the display of space-time changes in the post-disaster environment. In addition to the spatial and temporal scale, papers were also requested which address approaches for the collection and display of disaster-related ephemeral and dynamic data, as well as mechanisms for disseminating the resulting spatial data to policy-makers and to the public.
