| Résumé | (disponible en anglais seulement)
Multi-polarized Radarsat-2 SAR imagery is used to monitor seasonal lake ice within three National Parks in the Canadian Arctic. In spring, HH and HV backscatter
thresholds are used to classify lake ice versus open water; these classifications are used to produce ice-off date maps showing inter-lake diversity in melt duration. Classification accuracies and sources of error are discussed. In autumn,
preliminary analysis illustrates the challenges of monitoring lake ice freeze-up. In winter, polarimetric parameters are used to infer lake ice characteristics. |
