Hurricane Katrina Aftermath, ORBIMAGE. The breakthrough of the levees in New Orleans, along Surekote Road and opposite to the Galvez St. Wharf.

Initial imagery captured during the first pass of ORBIMAGE’s high resolution Orbview-3 satellite over Downtown New Orleans clearly shows broad area flooding and water encroachment throughout both commercial and residential areas.
