Paper Abstract

Portuguese coastal wetlands are located in estuaries and coastal lagoons. Due to physiographic patterns of tidal flats and salt-marshes and the geometric resolution of the pixels of the multispectral scanning system (MSS) and the thematic mapper (TM) Landsat imagery, only the large estuarine intertidal systems of Aveiro and Ria Formosa provide carthographic documents for land use planning. The wetlands systems and the water turbidity were classified using digital processing of the radiometric responses of the vegetation, the soils, and the water. The procedures of the digital processing were filtering, contrast enhancements, vegetation ratios, principal components analysis, and unispectral and multispectral rectangular classifications.
