PE&RS July 2008

This month’s cover showcases Western Air Maps, Inc.’s rapid response imagery of the Rock River ice jam and fl ood at Vandruff-Carr Island (Rock Island, Illinois) on March 6th, 2008. The imagery was acquired at the urgent request of the U.S. Army Corps of Engineers Mississippi Valley Region – Rock Island District. The oblique cover imagery is accompanied in the right margin by stereo pairs of the island’s quarry area and surrounding ice flows. The use of a stereoscope with these images best illustrates the potential dangers of flooding in concert with ice blockages (the river flows top to bottom of page; East to West). Photogrammetric imagery was requisitioned, planned, and acquired in just over six hours.

This month’s Highlight article chronicles all of the coordination and mission planning involved in successfully capturing this event for public record and hydrologic study by the U.S. Army Corps of Engineers.
