ETH-GQS: An estimation of geoid-to-quasigeoid separation over Ethiopia
The determination of accurate orthometric or normal heights remains one of the main challenges for the geodetic community in Ethiopia. These heights are required for geodetic and geodynamic scientific research as well as for extensive engineering ...

Efficient methods to convert LiDAR-derived ellipsoid heights to orthometric heights
Abstract Nowadays cartographic products are usually obtained from data sources which provide large amount of data. LiDAR acquisition system is a good example of the great quantity of data obtained, such as points with spatial coordinates in a determined reference system. The height of these points is usually related to a global ellipsoid (e.g. WGS84),

Polynomial interpolation methods in development of local geoid model
In geodesy three surfaces, the physical surface of the earth, the geoid and the reference ellipsoid are encountered giving rise to orthometric height (h), the ellipsoidal height (H) and the geoidal separation (N).

STRATEGIES FOR THE ACCURATE DETERMINATION OF ORTHOMETRIC HEIGHTS FROM GPS [PDF]
AbstractIn order for Global Positioning System (GPS) derived ellipsoidal heights to have any physical meaning in a surveying or engineering application, they must be transformed to orthometric heights. A practical approach is presented where gravimetrically and geometrically derived geoid heights are combined to accurately recover orthometric heights ...
