Résumé(disponible en anglais seulement)
In 2010, the Canadian Hydrographic Service (CHS) in collaboration with Canadian Geodetic Survey (CGS) began development of the CVDCW project. The goal is to develop a surface connecting chart datum (CD) to the national geodetic reference frame which captures the relevant spatial variability as modeled by integrating ocean models, water levels, GPS observations, sea level trends, satellite altimetry, and a geoid model. The CVDCW's CD surface will define a new hydrographic datum for Canada; other CVDCW surfaces (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. We have developed a national approach which is flexible enough to adapt to regional differences and permits the integration of new gauge and model data and improved methods as they become available. Given that Canada has more than 200,000 km of shoreline and the large-scale approach of the CVDCW, many aspects of our method are innovative and have not, to our knowledge, been used by other hydrographic organizations in the world. A prototype of the CVDCW is now available for all Canadian Tidal Waters. Realizations of the CVDCW are expected to evolve quickly in the next few years, as the prototypes are improved and validated.
