Abstract
A method for reconciling ground-level discrepancies between the displayed path of a moving body and a terrain model in a graphical simulation, including the steps of (1) examining the individual data points describing a recorded trip by a vehicle, (2) determining which of the data points correspond to points when the vehicle was actually on the ground, (3) determining the altitude difference between the recorded altitude data and the terrain model at each of the determined “on-ground” points, and (4) using the altitude difference to create a correction signal which can be applied either to the recorded altitude data or the terrain model.
