Abstract
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.
Claims20
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.
A geographic information display system comprising:
- a monitoring system comprising:
- a positioning system configured to determine and record a plurality of positions of a watercraft as the watercraft travels across a body of water;
- at least one sonar system configured to receive and record 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 position of the watercraft;
- and
- a processor configured to:
- align each set of sonar pings to the corresponding one of the plurality of positions at which each set of sonar pings was received;
- and
- generate a sonar image using the plurality of sets of sonar pings;
- and
- a display configured to:
- display 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, and
- wherein the indicating point represents one of the plurality of positions of the watercraft;
- and
- display 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.
