SummaryWe will use high resolution TerraSAR-X data in order to conduct innovative land subsidence detection studies on a triplet of major Canadian urban centers. At the western coast, Canada’s largest coastal city, Vancouver, located in the Cascadia Subduction Zone will be studied using InSAR and monthly high resolution products to detect vertical movements. Further east, approximately 80 km from the front ranges of the Canadian Rocky Mountains lies Calgary, Canada’s fastest growing city. Alberta relies on its agriculture and oilpatch industries and studies on the vertical displacement of this urban center are of particular importance to curb urban sprawl resulting in increasing developments. Finally, Canada’s largest city, Toronto will be closely monitored to include profiles of Lake Ontario’s changes shores that bound the city to the south. Our team will use their extensive skills in height systems, digital terrain and elevation modeling, geodynamics, geodesy, SAR and InSAR, to provide unique assessments on the detected land subsidence of these three important urban centers using monthly samples from both the high resolution Spotlight and ScanSAR images.
