TRIP REPLAY FOR AN AQUATIC GEOGRAPHIC INFORMATION SYSTEM

摘要

A method of replaying measured data points includes receiving positions of a watercraft from a monitoring system, receiving sonar pings of a water body from the monitoring system at the positions of the watercraft, and aligning each of the sonar pings to each of the watercraft positions at which each of the sonar pings was taken. The method also includes generating a sonar image using the of sonar pings, providing a map of the water body, displaying the map including a pathway with an indicating point with the pathway representing the watercraft positions, and displaying the sonar image including an indicating line alongside of the contour map wherein the indicating line on the sonar image corresponds to the indicating point on the pathway.
