Issues of terrestrial geodetic datum definition in VLBI data analysis
, 2023 The geodetic datum describes the absolute location, orientation and scale of the observed system with respect to a target frame. Since Very Long Baseline Interferometry (VLBI) observations only provide information on the relative relationships between ...

User defined function for transformation of ellipsoidal coordinates [PDF]
Podzemni Radovi, 2014 The topographic plane of the Earth has irregular shape, and for the purpose of mathematical defining, it is to be approximated by rotational ellipsoid. As local geodetic datum, rotational ellipsoids of various sizes are used in the world.

Geoplanning: Journal of Geomatics and Planning, 2017 Most developing countries like Ghana are yet to adopt the geocentric datum for its surveying and mapping purposes. It is well known and documented that non-geocentric datums based on its establishment have more distortions in height compared with ...
