Geoid Models for Indian Territory

Geoid modelling for India is a complex, exhaustive and continuous task because of its large area and tremendous varieties of surface. This paper reviews available geoid models for Indian Territory developed through geometric, gravimetric and hybrid methods for Northern, Eastern, Southern, and Western regions and presents a summary of further scope for the geoid development in India.

Gravimetric Geoid Determination by Using Terrestrial and Satellite-derived Data

Being a fundamental vertical reference surface, the use of the geoid is not limited to geodesy/geodetic applications. It is also used, but not limited to, in geophysics (i.e. interpretation of the Earth’s internal structure, solid earth science), geology (i.e. subsurface delineation), oceanography, and mapping/geographic information systems (GIS)/national spatial development infrastructure (NSD...

A 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...
