Abstract

Remote-sensing techniques were utilized to investigate selected wetland environments in the Nebraska Sandhills. The intent was to determine which remote-sensing technique might prove most effective in delineating three general classes of wetlands, i.e., open water, marsh, and subirrigated meadow. Two specific techniques were utilized in the research, namely the computer classification of Landsat digital data derived from computer compatible tapes and the video-digitization and classification of color-infrared aerial photography. As a result of comparative analysis of both systems, it was felt that the use of Landsat digital data is the optimum mechanism for classifying and mapping for three general wetland classes. It was found that both systems were useful but with the Landsat system all three classes were more easily separated.
