Land covers and uses are dynamically being changed over the time. Detection and identification of these changes is necessary and is the first step of any study or planning for natural resource management. Synthetic Aperture Radar (SAR) imagery, thanks to its independence to weather conditions and sun illumination, is a powerful tool for these studies. In this research an unsupervised change detection...
The region of interest is located approximately in the downstream part of the Mackenzie River, Canada. Our study focuses on guidelines to process RADARSAT-1 interferometric C-band data in a permafrost environment and monitor permafrost activity and landslide motion over 18 month period. From the interferometric method (D-InSAR) on ~100 interferograms, the main conclusions are (1) a high resolution...
In this study we used differential InSAR techniques to monitor landslide slide and permafrost activity at a site along the Mackenzie Valley Pipeline Corridor. Our results that motion are about 3 times more on exposed burnt slopes than the adjacent areas. The maximum activity is in September, probability related to gradual accumulated increases in soil temperatures.
The Coherent Targets Monitoring technique is providing superior ground deformation mapping compared with standard interferometry based on one pair of Master/Slave scenes. This is because using a larger data set it is possible to estimate and correct for additional phase error sources. Also the point targets detected as coherent targets are generally characterized by stronger signal that provides more...
