Author Affiliations +
The U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and the Environmental Protection Agency are charged with the responsibility to jointly manage the nation''s wetlands in accordance with the Clean Water Act and the Rivers and Harbors Act. The Corps'' role is enforcement of regulations concerning dredging and filling of specific types and areas of wetlands that fall within jurisdictional boundaries. Current research is being conducted to enhance the field scientist''s ability to manage these ecosystems using digital aerial photography, image processing, and photo interpretation logic. This paper presents techniques used to scan (digitize), archive, and utilize digital aerial photography for environmental resource management using a photogrammetrically accurate, CCD-based scanner. Spectral characteristics of the imagery and useful image processing routines to enhance the resulting raster file(s) for interpretation are discussed.
