Geoid determination is nowadays an important scientific problem in the fields of Geosciences. Ellipsoidal and orthometric heights are commonly used height systems in geodesy. Ellipsoidal height, measured from satellite such as GPS and GLONASS, is reckoned from ellipsoid. On the other hand orthometric height is measured from geoid. Although orthometric height has physical meaning, ellipsoidal height has just mathematical definition. Geoid height is a transformation parameter between these heights systems and a tool for rational usage of coordinates obtained from satellite measurements. Fuzzy logic theory has been popular in many different scientific, engineering fields and many geodetic problems have been solved by using fuzzy logic recently. In this study, theory and how to calculate geoid height by Fuzzy logic using Matlab is explained and a case study in Burdur (Turkey) is performed. Calculations are interpreted, discussed and conclusion is drawn.
