The landscapes in the Northwest Territories (NWT, Canada) are amongst the most rapidly changing in the world due to climate-induced permafrost thaw. This presentation provides an overview of recent remote sensing and mapping investigations of permafrost thaw landslides across different spatial and temporal scales in the NWT. A common thread of ever-expanding geospatial capabilities (remote sensing, machine learning) is juxtaposed against rapidly intensifying permafrost thaw with many growi...

Please join us for the MDA-hosted workshop on multi-band SAR presented by MDA (Canada), Iceye (Finland) and VENG (Argentina).  After presenting SAR fundamentals, we will dive deep into the specifications of X-band (Iceye), C-band (RADARSAT-2) and L-band (SAOCOM) missions, as well as the sensors’ merit and strength in specific applications that are of relevance to Canada.  The last hour would be Q&As and discussion.

The United States’ National Geodetic Survey (NGS) plans to modernize their National Spatial Reference System (NSRS) in 2025, including adopting a new dynamic geometric reference (the North American Terrestrial Reference Frame of 2022 (NATRF2022)) and a new geoid-based height system (the North American-Pacific Geopotential Datum of 2022 (NAPGD2022)). To ensure continued geospatial referencing compatibility, the Canadian Geodetic Survey (CGS) plans to modernize the Canadian Spatial Reference Sy...
