Seminar – 22 May – Precise Change Detection with Airborne Interferometric Synthetic Aperture Radar (InSAR) & Optical Photogrammetry Data and its application to Active Permafrost Regions.

Usman Iqbal Ahmed will be presenting Precise Change Detection with Airborne Interferometric Synthetic Aperture Radar (InSAR) & Optical Photogrammetry Data and its application to Active Permafrost Regions.

Date: 22 May 2024
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

Permafrost thaw can cause several problems; the ground becomes unstable and can cause damage to infrastructure such as roads, buildings, and pipelines. 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.

Seminar – 1 May – Advancing Arctic coastal erosion measurement and monitoring through UAV-SfM and object-based image analysis.

Andrew Clark will be presenting Advancing Arctic coastal erosion measurement and monitoring through UAV-SfM and object-based image analysis.

Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

Arctic coasts are vast and exhibit some of the highest rates of erosion in the World due to the presence of permafrost. Rates of erosion are expected to increase with warming air and water temperatures, reductions in Arctic sea ice extent and duration, sea level rise, and increased storm severity and frequency. This presentation will describe the use of emerging technologies (UAV-SfM and OBIA) to further our understanding of Arctic coastal processes, specifically, volumetric erosion, and broad scale delineation of multiple shoreline proxies for monitoring and quantification of erosion.
