RADARSAT-1, the first Canadian SAR remote sensing satellite, was launched on November 4, 1995. After commissioning, it was put in to routine operations on April 1, 1996. Since then, it has been operating successfully, even after completing its five and a quarter years of design lifetime, and providing data to users for their intended applications.(More)
A warming climate influences boreal forest productivity, dynamics, and disturbance regimes. We used ecosystem models and 250 m satellite Normalized Difference Vegetation Index (NDVI) data averaged over the growing season (GSN) to model current, and estimate future, ecosystem performance. We modeled Expected Ecosystem Performance (EEP), or anticipated(More)
In this paper, we will present the results of several case studies focusing on RADARSAT-2 InSAR monitoring of several different types of landslides and the uses of enhanced RADARSAT-2 polarimetric composites for surficial geological and terrain mapping in Canada. InSAR techniques are increasingly being used in slope stability assessment [1, 2 3]. Our(More)
In this study we analysed 55 RADARSAT 1 InSAR images acquired from August 2006-July 2010 to monitor deformation of permafrost slopes along the Mackenzie Valley Pipeline Corridor. Results from two corner reflectors installed near a landslide show a 10 and 20 cm motion from 2006-2010. Our InSAR measurement also shows that the lower steeper slope is moving(More)
