A collection of SAR methodologies for monitoring wetlands.

摘要: Wetlands are an important natural resource that requires monitoring. A key step in environmental monitoring is to map the locations and characteristics of better enable assessment change over time. Synthetic Aperture Radar (SAR) systems helpful this way for wetland resources because their data can be used monitor changes surface water extent, saturated soils, flooded vegetation, vegetation cover. We review a few techniques demonstrate SAR capabilities monitoring, including commonly method grey-level thresholding mapping highlighting approaches polarimetric decompositions from one class land cover another. use Curvelet-based detection Wishart-Chernoff Distance show how they substantially improve flagging areas change, respectively. recommend increasing availability proven ability these various components wetlands mean should considered as critical component system.
