Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2004 Elipsoidal heights determined by GPS is different from orthometric heights used insurveying applications. Therefore, elipsoidal height determined by GPS is transformed to orthometricheight. It can be used several transformation methods to do this transformation.

International Journal of Advanced Geosciences, 2017 The Global navigation satellite systems (GNSS) has imparted positively on civilian positioning & surveying in the horizontal component in Nigeria for the past two decades. The GNSS receivers’ data are longitude, latitude & elevation. However, the vertical distance measurement have not been fully exploited by geodetic and land surveyors.

Models for extracting vertical crustal movements from leveling data [PDF]
Various adjustment strategies are being used in North America to obtain vertical crustal movements from repeated leveling. The more successful models utilize polynomials or multiquadric analysis to describe elevation change with a velocity surface. Other
