 Synthetic aperture radar, SAR, systems have been shown to be effective tools for mapping and monitoring wetland resources. Gray-level thresholding is often used to map surface water and highlight changes in its extent, while polarimetric decompositions can be used to identify changes in flooded vegetation and flagging areas of change. Additionally, the curvilet-based change detection and Wishart-Kurnoff distance approaches can substantially improve mapping of flooded vegetation and flagging areas of change, respectively. The increasing availability of SAR data and its proven ability to map various components of wetlands make it a valuable tool for wetland monitoring.
