Real-Time GIS Assists South Carolina in Managing Hurricane Floyd EvacuationArticle provided by Intergraph CorporationPutting GIS on the Web lntergraph's GeoMedia@ Web Map is Windows-based software that allows users to combine and distribute GIS and other digital information from multiple data sources in virtually any type of raster or vector file format and publish them over an intranet or Internet. Its most potent feature is that its maps can be displayed and queried with any industry standard Web browser. "We were familiar with the concept of publishing GIS data over the Internet, but the Emergency Preparedness Division did not want its personnel to have to learn a new software package [i.e., GIS]," said Don McElveen, the GIS Manager in SCDOT's Mapping and Graphics office, which is responsible for producing maps of department infrastructure and is spearheading development of new GIS applications. This solution seemed ideal since nearly everyone in the South Carolina organization knew how to use a browser and was familiar with the Windows environment. Because the product had been developed for use in a broad-range of applications, Intergraph designed it to handle GIS files in their native formats from several software systems as well as satellite imagery, photographs, video, audio, and vector maps. This proved valuable to SCDOT which had four distinct data types it wanted to bring together to make its Hurricane Evacuation Decision Support Solution a reality: vehicle count totals from remote recording devices around the state official Emergency Evacuation Route map from the existing SCDOT GIS, road closure and detour maps from a variety of state agencies depending on the emergency, and real-time weather information from the Internet.
