| Résumé | (disponible en anglais seulement)
The Canadian Hydrographic Service with support from the Canadian Geodetic Survey has recently developed a suite of Hydrographic Vertical Separation Surfaces
(HyVSEPs) for the tidal waters of Canada, primarily for use in sounding reduction and hydrography. HyVSEPs map tidal level targets and hydrographic datums to a geodetic reference ellipsoid by integrating ocean models, water levels, GNSS observations,
sea level trends, satellite altimetry, and a geoid model. The HyVSEP for chart datum in tidal waters will define a new hydrographic datum for much of Canada; other HyVSEPs (e.g. low water, high water) will provide fundamental pieces of information
for coastal studies, climate change adaptation, and the definition of the Canadian shoreline and offshore boundaries.
In this presentation we will review updates to our methods and show how they improve the quality of our products. We will also
address remaining issues, such as the transformation between hydrographic datums at the Canada-US border. Finally, we will highlight applications of the HyVSEPs currently being explored which will also be useful across multiple disciplines. |
