AbstractSAR-based image thresholding can be used to detect and map open water body locations and extents. The selection of a reasonable and consistent thresholding approach can be challenging across many complex landcover types. Besides SAR acquisition characteristics, environmental factors (e.g., emergent vegetation and wind-induced roughening of the water) can cause water locally increased backscatter relative to the characteristic dark appearance of water in SAR imagery. This is where much attention has been recently devoted to a variety of thresholding methodologies for surface water monitoring with SAR imagery.
