LOCAL GEOID DETERMINATION FOR KADINHANI REGION

GPS (Local Positioning System) technique is still the most applied positioning system in practical applications and engineering projects in our country and in the world. Since GPS measuring is commonly used in every kind of geodesic study, heights used in practice can be obtained easily in demanded accuracy from GPS. However it is necessary to determine geoid which had enough precision in working place. Because geoid is a natural relation between the ellipsoidal height (h) determined by satellite and orthometric height determined in different ways according to the type of data and methods are used. In this study, a test area was selected in Kadinhani district of Konya city to determine the local geoid. In previous years, local geodesic network in Kadinhani region was established apt to the coordinate system of the country and the network has been used to the present. Geoid undulations were determined by establishing suitable points to intensify the net for the purpose of the test.
