Abstract
The height of Mean Dynamic Topography (MDT) is a distance of Mean Sea Surface from the Geoid. MDT (heights) can be estimated using altimetry data at track points. For further and easy use of MDT it’s heights must be recalculted (interpolated) at a certain resolution grids as so-called MDT models. This proccess can be done with interpolation based on Linear Prediction. As practice of this one program named “MDT INTERPOLATION” was written and applied for the ENVISAT 81st cycle data in order to determine MDT in the East Sea. The results of interpolation show that it is adequate to use only track points within 1° radius cicle surrounding the checked point (not all the observed point in considered region).
