Remote Sensing of Wetland Types: Semiarid Wetlands of Southern Hemisphere
A number of substantive semiarid wetlands occur, with notable examples being in southern Africa and Australia. The seasonal nature of these wetlands requires regular observations with both optical and radar data providing different but often complementary information. Focusing on the Okavango Delta in Botswana, the Sudd Wetlands in South Sudan, and the Murray Darling Basin in Australia, the role of these different sensor types has been used to classify wetlands and understand dynamics and pressures. A wide range of descriptors of wetlands ares also provided by integrating data of differing spatial resolutions (e.g., RapidEye to MODIS) and temporal frequencies (daily to seasonal).
