On the Definition and Realization of a Global Vertical Datum
AGlobal Vertical Datum (GVD) is naturally defined by the geoid, and there is a well-established consensus to adopt Gauss-Bessel-Listing's definition of the geoid (i.e. as being the level surface of the Earth's gravity field that best fits the undisturbed sea level). Themain problem in defining the geoid is therefore to fix its constant geopotential (W0). Nevertheless, this definition can be int...
متن کاملA Gravimetric Geoid Model as a Vertical Datum in Canada
The need for a new vertical datum in Canada dates back to 1976 when a study group at the Geodetic Survey Division (GSD) of Natural Resources Canada investigated problems related to the existing vertical reference system (CGVD28) and recommended a redefinition of the vertical datum. The US National Geodetic Survey and GSD cooperated in the development of a new North American Vertical Datum (NAVD...
متن کاملVertical datum conversion in the Lake Erie coastal area
Seamless integration of land-elevation and water-depth information in coastal environments is required in many geospatial applications and decision-making processes. Vertical datum conversion is the central component of the integration process. This study introduces a methodology of vertical datum conversion in Lake Erie, which utilizes the public published models and toolkits developed by Nati...
متن کاملProgress Towards a Gravimetric Geoid for New Zealand and a Single National Vertical Datum
New Zealand, unlike most countries, does not have a single national vertical datum. Instead, twelve separate and poorly linked primary levelling networks tied to twelve different tide gauges are used. The current vertical datums are based on the false assumption that mean sea level, measured at the twelve tide gauges, corresponds to the same equipotential surface. Due to the effects of long-per...
متن کاملChart Datum for Hydrography
This paper sets out to discuss ongoing activities in the tide and chart datum components of hydrography and charting. It expands on the paper presented at FIG (Fédération Internationale des Géomètres) in Brighton 1998 by Mr Matt Higgins and is a revised and updated version of the paper Chart Datum for Hydrography by GPS delivered by the present authors to the Survey 99 Congress, Sunshine Coast,...
