Unmanned aerial systems operators from the U.S. Army Corps of Engineers Research and Development Center, headquartered in Vicksburg, Mississippi, use drones to help assess homes and determine eligibility for the Blue Roof program. The team also uses the aerial imagery to verify that plastic sheeting was installed per contract specifications.
