Interferometry for coastal spit geomorphology mapping

This study presents new approach for mapping coastal geomorphology changes from interferometric synthetic aperture radar (InSAR) data. Two RADARSTA-1 SAR standard beam data were processed to acquire digital elevation of surface spit topographic information from INSAR. Furthermore, Fuzzy B-spline mod...
