Refined geoid model for the United Arab Emirates

A precise gravimetric geoid plays a role of tremendous importance in successful military operations. This work is aimed to determine the precise gravimetric geoid of the United Arab Emirates (UAE). In doing so, the GRAVSOFT package is used in computing the 1-D and 2-D FFT gravimetric geoids for th...
