Remote Sensing Inland Wetlands: A Multispectral Approach

摘要

Airborne Multispectral Scanner (MSS) data, large-scale aerial photography, and LANDSAT MSS and Thematic Mapper (TM) data were used to map a variety of wetland conditions along the Savannah River watershed in South Carolina. Predawn thermal infrared MSS imagery was analyzed to map the spatial distribution and migration of thermal effluent entering a portion of the Savannah River floodplain and the Savannah River below Augusta, Georgia. Daytime airborne MSS data were used to classify specific wetland vegetation types and associate them with their apparent (remotely sensed) temperature. Large scale, multiple data aerial photography were ideally suited to follow the growth of vegetational changes associated with the thermal discharges into the floodplain. LANDSAT MSS imagery obtained in the spring was used effectively to map the entire Savannah River watershed. LANDSAT TM imagery obtained in the summer was of limited use in regional wetland mapping. 21 refs., 11 figs., 3 tabs. (ERA citation 10:045181)
