A Derived Model of Alaskan Sea Surface Topography: a critical piece of the vertical datum transformation for ellipsoid referenced hydrography
With coasts that form three >1700 km arms which spiral outward from a point near Kodiak Island, Alaska provides a large-scale site for the study of the relationship between geodesy and sea level. The surface of a static, uniform ocean will follow an equipotential, orthometric surface. Long lived geostrophic currents or prevailing winds result in localized and large scale variations between its ...
متن کاملOn 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 کاملTwo-Dimensional Boundary-Conforming Orthogonal Grids for External and Internal Flows Using Schwarz-Christoffel Transformation
In this paper, a Schwarz-Christoffel method for generating two-dimensional grids for a variety of complex internal and external flow configurations based on the numerical integration procedure of the Schwarz-Christoffel transformation has been developed by using Mathematica, which is a general purpose symbolic-numerical-graphical mathematics software. This method is highly accurate (fifth order...
