The Power of Hurricane GustavGustav, which made landfall as a category 2 hurricane on Monday, September 1, was less potent than originally predicted but devastating nonetheless. Packed with over 100-mile-an-hour winds, torrential rain, and the threat of tornadoes, Hurricane Gustav resulted in U.S. property damages estimated in the billions of dollars. GIS helped mobilize responders, equipment, and supplies. It assisted in evacuations that resulted in nearly two million people, including many thousands of elderly and infirm, moving to safety in an organized, efficient manner. Many of the evacuation plans, which included multiple means of transportation, were assessed, implemented, and monitored using GIS.
Personnel determined appropriate evacuation shelters and the most expedient routes to the shelters as well as monitored and managed logistics necessary to sustain shelter operations. In addition, other analyses were performed to understand how critical infrastructures might be impacted by the storm (potential power outages, transportation network impairment, government facility damage, etc.). From these analyses, contingencies were developed for maintaining government operations and business continuity using other resources. GIS analysts fused diverse data types from multiple sources including satellite imagery; GPS coordinates; live weather feeds; and utility grid, parcel, and street information. Maps were developed that displayed damaged buildings and hazardous areas, functioning and downed communication networks, power outages, road closures, and food and safe water sources after the hurricane hit.
These maps aided in identifying recovery priorities and communicating information to other government officials, the public, and the media. News outlets used GIS data and mapping to add data-rich graphics to their stories. Perhaps most important, GIS specialists and virtual networks of organizations collaborating and sharing resources played a key role in the response. The U.S. Department of Homeland Security added GIS analysts in the national operation center to increase support during the event. The deployment of GIS helped eliminate redundant work and facilitated greater preparedness, collaboration, and communication. "The ability to pull together a common operating picture across jurisdictions is better today than at any other time," says Johnson. "I think that people have begun to appreciate the value of the technology and anticipate having it in place and ready to deploy when emergencies occur."
