1. A method of replaying measured data points, the method comprising: receiving, via a monitoring system, a plurality of positions of a watercraft as the watercraft travels across a body of water; recording the received plurality of positions of the watercraft; receiving, via the monitoring system, a plurality of sets of sonar pings from the body of water as the watercraft travels across the body of water, wherein each set of sonar pings corresponds to one of the plurality of positions of the watercraft; recording the received plurality of sets of sonar pings; aligning each set of sonar pings to the corresponding one of the plurality of positions at which each set of the sonar pings was received; generating a sonar image using the plurality of sets of sonar pings; displaying a map of the body of water along with a pathway with an indicating point, wherein the pathway represents the plurality of positions of the watercraft as the watercraft traveled across the body of water, wherein the indicating point represents one of the plurality of positions of the watercraft; and displaying the sonar image along with an indicating line, wherein the indicating line on the sonar image represents a set of sonar pings that corresponds to the position of the watercraft represented by the indicating point on the pathway of the map.
