Abstract: A low-cost fleet operations quality management system for use with one or more vehicles which includes a data recording unit and separate memory subsystem mounted on each vehicle, a remotely located data collection station to collect, store and pre-process data from multiple vehicles, a centralized data storage and retrieval system designed to accept and assimilate recorded trip data, a web application designed to provide access to and analysis of the recorded trip data, and a graphical software application that can be used to view the recreated trip in a realistic simulated environment.

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.
