It can also cause erosion and changes in the landscape, which can have ecological and social impacts and disruption of indigenous ways of life. Monitoring these changes is a key factor in reducing the impact of such disasters as well as timely reaction\/adaptation to such changes. I am exploring the option of developing a change detection method using Airborne Synthetic Aperture Radar (SAR) Interferometry and Optical Photogrammetry data for precise change detection. I will present the results of our controlled experiment with simulated permafrost related changes to showcase the capability of our method in active permafrost thaw environments.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-1024x1024.jpeg\" alt=\"\" class=\"wp-image-6688\" srcset=\"https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-1024x1024.jpeg 1024w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-300x300.jpeg 300w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-150x150.jpeg 150w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-768x769.jpeg 768w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-12x12.jpeg 12w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2-45x45.jpeg 45w, https:\/\/permafrostnet.ca\/wp-content\/uploads\/2024\/03\/Usman-20230106_091644-2.jpeg 1283w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Usman Iqbal Ahmed&nbsp;will be presenting&nbsp;Precise Change Detection with Airborne Interferometric Synthetic Aperture Radar (InSAR) &amp; Optical Photogrammetry Data and its application to Active Permafrost Regions.
