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...

Join us in this training to learn about some of the latest and greatest features in ERDAS IMAGINE! With the exponentially increasing amount of data being collected in the world today, customized repeatable, batchable workflows are needed to extract as much valuable information from raw data as possible. The Spatial Modeler is the key to setting up these types of workflows. The creation of spatial models and the use of AI, machine learning and deep learning allow mo...

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...
