The investigation of the geodetic gravity approach

In this thesis study, gravity values and gravity anomalies of the points with identified latitudes, longitudes, orthometric and ellipsoidal heights in the area between 0 0 36.5 < 9 < 40.5 and 0 0 26.5 < X < 33 latitudes and longitudes will be determined by using EGM08, GECO, EIGN-6C4 geopotential models, REQTOPO2015 topography model and WGM2012 gravity model. After determining these values, the terrestrial data acquired by BGI (Bureau Gravimetrique International) and gravity anomaly values acquired by using the models within the scope of our study will be compared, the differences will be calculated and the mean squared errors (MSE) will be presented. We aim to determine the gravitational model which can be used to identify the most appropriate geoid that models the globe.
