The Oregon Department of Environmental Quality (DEQ), funded by the Oregon State Fire Marshal’s Office, and in partnership with the Oregon Public Health Division and Portland State University’s Center for Spatial Analysis and Research, has created a response tool aimed at providing key geographic information needed to guide response efforts to emergency response personnel – the Oregon Incident Response Information System (OR-IRIS). Affectionately nicknamed the Oregon Map of Everything, OR-IRIS leverages existing GIS datasets useful to understanding the natural, physical and jurisdictional setting of a hazardous release so that a safe, appropriate and efficient response can be conducted. OR-IRIS consists of pre-packaged GIS layers within a common projection, in an ordered group/sequence designed to provide critical information first, and in a format that allows for exploration and analysis by those without advanced GIS skills. Through collaboration with Portland State University’s Center for Spatial Analysis and Research, the cost for the first generation of the project has been kept impressively low. The impact of the project is not yet known, but promises to increase public safety and the quality of Oregon’s environment well beyond its modest costs to develop.
