| 摘 要： | Geopotential, dynamic, orthometric and normal height systems and the corrections related to these systems are evaluated in this paper. Along two different routes, with a length of about 5 kilometers, precise leveling and gravity measurements are done. One of the routes is in an even field while the other is in a rough field. The magnitudes of orthometric, normal and dynamic corrections are calculated for each route. Orthometric, dynamic, and normal height differences are acquired by adding the corrections to the height differences obtained from geometric leveling. The magnitudes of the corrections between the two routes are compared. In addition, by subtracting orthometric, dynamic, and normal heights from geometric leveling, deviations of these heights from geometric leveling are counted.

| Abstract: | Geopotential, dynamic, orthometric and normal height systems and the corrections related to these systems are evaluated in
this paper. Along two different routes, with a length of about 5 kilometers, precise leveling and gravity measurements are
done. One of the routes is in an even field while the other is in a rough field. The magnitudes of orthometric, normal and
dynamic corrections are calculated for each route. Orthometric, dynamic, and normal height differences are acquired by adding
the corrections to the height differences obtained from geometric leveling. The magnitudes of the corrections between the
two routes are compared. In addition, by subtracting orthometric, dynamic, and normal heights from geometric leveling, deviations
of these heights from geometric leveling are counted.
