During a mine countermeasures demonstration, a 55-gallon drum was placed at the base of a bridge stanchion to simulate an underwater improvised explosive device/mine. The new object identified in the "After" sonar imagery above is the 55-gallon drum. A drum of this size filled with explosives and a detonating mechanism would be enough to destroy the stanchion resulting in bridge collapse. Using methods of change detection as illustrated in the animation, underwater threats can be identified for engagement and neutralization.
Underwater Mapping and GIS
Orca Maritime, Inc. will compile all the elements of a comprehensive underwater survey to deliver an accurate layered Geographic Information System (GIS), including 3-dimensional renderings of the bottom surface, submerged infrastructure such as pipelines and cables, a detailed database of bottom contacts, as well as any other pertinent environmental data. These GIS products support emergency action plans for port security organizations, engineering maintenance programs, and environmental protection initiatives.
