Development and Application of a Spatial Database for Emergency ManagementOperations: 1993 Midwest Flood

摘要

During natural and man-made emergencies, there is a need for the rapiddevelopment of spatial databases to support recovery efforts. A spatial database was developed to support the U.S. Army Corps of Engineers Disaster Field Offices during the flooding that took place in the Midwest during the summer of 1993. The spatial database contains roads, railroads, hydrography, county boundaries and inundation data for seven rivers located in the Mississippi River basin. The spatial data came from a variety of sources, including U.S. Census Bureau TIGER/Line files, U.S. Geological Survey Digital Line Graphs and satellite imagery. An application of the spatial database is also described. Maps were produced showing roads, railways, hydrography, county boundaries and, when available, inundation data. These maps were then distributed to assist in the recovery efforts and future planning.
