| Abstract | The objective of the research study is to use the synergy of 3D empirical (Rational Function Model (RFM) and physical (Toutin's) geometric models to develop a "new hybrid" model for the geometric
processing of Radarsat-2 data without collecting ground control point (GCP). After independently evaluating the processing and the accuracy of each model using accurate differential GPS points, RFM was thus used to generate few "virtual" RFM points
at the highest elevation of the study site. In addition to information of the metadata, these "virtual" points were input as GCPs in Toutin's model. This “new hybrid model consistently achieved pixel accuracy, with better results for steep looking
angles than the two other models. Its main advantage was, in addition, to be used without collecting GCP, increasing the applicability of Radarsat-2 data in remote areas. |
