Abstract
Generally, the contrast between water and land in SAR images decreases with decreasing incidence angle. Thus, surface water detection by intensity thresholding requires high incidence angle data. In this work we demonstrate a texture based surface water detector that produces accurate results, independently of the incidence angle.
