After the 1993 Midwest flood, a research team conducted one of the largest aerial mapping projects in U.S. history—a year-long, $3.7 million effort that demonstrates the utility of photogrammetry based on the Global Positioning System and provides a benchmark for future large-scale mapping programs. The search for answers to the Midwest's flood threat began in late 1993 when the White House Office of Science and Technology formed the Scientific Assessment and Strategy Team (SAST), a multidisciplinary panel of government engineers and scientists charged with helping formulate federal flood recovery and mitigation plans for the stricken region.
