Geometric Techniques of Local Geoid Determination



Author(s): Ojanikele Willie Augustine, Ezeh FC

Abstract:

Local geoid determination employing geometric techniques harnesses positional data from GNSS and conventional leveling. Such methodologies ranging from polynomial interpolation to least squares collocation provide centimeter level accuracy for local geoid undulations, crucial for conversion of ellipsoidal heights to orthometric heights. This study reviews core methods, exemplifies their application, and assesses their performance in various regions.
