Arctic Shoreline Delineation & Feature Detection Using RADARSAT-1 Interferometry: Case Study Over Alert
Extensive ground truth carried out in and around Alert in 2002 permitting testing the geometric calibration of RADARSAT- 1, optimizing the capability of RADARSAT- 1 interferometry to delineate coastlines and riverbeds in an Arctic environment, and investigating the detection of various targets and f...
