The Canadian Geodetic Vertical Datum / Webinaire: Le Système canadien de référence altimétrique

The Canadian Geodetic Vertical Datum of 2013 (CGVD2013) is a modern geoid-based height reference system, representing the zero-elevation surface for Canada. It was released in 2013, but formally adopted in 2015 (Canada Gazette). CGVD2013 replaced the aging levelling/benchmarks-construct CGVD28. This webinar first gives an update on the adoption of CGVD2013 across the country. Second, it explains the relation and transformation between CGVD2013 and the upcoming U.S. lead North American-Pacific Geopotential Datum of 2022 (NAPGD2022) in 2025. Finally, it presents prospects of CGVD2013, including enablers and barriers for its provincial adoption and recommendations to land surveyors in the determination of elevations.
