Evaluation of different geodetic heights

Evaluation of Different Geodetic Heights One of the most important properties expected from geodetic height systems is elimination effect of the dependence to the route; the other is to be minimum of corrections that are added to the height differences obtained from levelling. In this study, geopotential, dynamic, orthometric, and normal height systems, and the corrections related to these systems have been evaluated. In two different routes that have length about 5 kilometres, precise levelling and gravity measurements have been done. One of these routes is in a even field, and the other is in a rough field. The magnitudes of orthometric, normal, and dynamic corrections have been calculated for each route. Orthometric, dynamic, and normal height differences have been acquired by adding the corrections to the height differences obtained from geometric levelling. The magnitudes of the corrections for two routes have been compared each other. In addition, subtracting orthometric, dynamic, and normal heights from the geometric levelling, how many deviations of these heights from geometric levelling have been seen.
