Use of Digital Multispectral Video for Littoral Zone Applications

摘要

Digital multispectral videography was obtained over Parramore Island, VA in an effort to extract information concerning vegetation communities, micro elevation changes, soil texture, and soil moisture conditions. These information categories would then be used to assist in tactical near-shore decisions, such as cross country mobility, avenues of approach, bivouac sites, and landing areas, and to also provide greater insight concerning environmental management activities within installation natural resource communities. Flightlines extending from the open ocean to the bayside lagoons were collected at both 0.25 meter and 0.5 meter ground spatial resolution. Through image analysis and ground truth verification, the multispectral videography was successful in separating the basic ecological communities of seaside beach, undulating dune-ridge/valley complex, maritime forest, salt marsh, tidal flat, and bays.
