4. Helping the World to Communicate Geographically © 2004, Open Geospatial Consortium, Inc.4 OGC Sensor Web Scientific View Analysts and emergency managers monitor conditions in near real time spatial- temporal context. Policy-maker View Hot spot areas are correlated with population data and other geospatial data. These maps are used to make decisions about evacuation routes and reoccupation zones. Media/Public View Color coded symbols are used to indicate areas at risk and road closures. Other features and landmarks such as roads, buildings, and water bodies are used to add context. From Critical Infrastructure Protection Initiative September 2003
