Claim 19:
20. A method for presenting marine data, the method comprising:
causing, on a display, presentation of a chart including at least a portion of a body of water;
causing, on the display, presentation of a representation of a watercraft at a position in the chart corresponding to a current location of the watercraft;
determining, based on a beam shape corresponding to at least one sonar transducer, a sonar beam zone corresponding to a sonar coverage of the underwater environment of the body of water provided by the at least one sonar transducer, wherein the at least one sonar transducer is associated with the watercraft, wherein the at least one sonar transducer is configured to emit one or more sonar beams into the underwater environment of the body of water in a direction relative to the watercraft, wherein the one or more sonar beams are each emitted according to the beam shape;
receiving sonar return data from the at least one sonar transducer;
determining an object within the sonar return data,
determining, based on the sonar return data, a position of the object within the sonar beam zone;
determining, based on the sonar beam zone, a sonar beam footprint, wherein the sonar beam footprint corresponds to a projection of the sonar beam zone onto a bottom surface of the body of water;
determining a location within the sonar beam footprint for the object, wherein the determined location corresponds to the position of the object within the sonar beam zone relative to the watercraft and projected onto the bottom surface of the body of water; and
causing, on the display, presentation of the sonar beam footprint and an indication of the object within the sonar beam footprint at the determined location, wherein the sonar beam footprint and the indication of the object are presented on the chart and configured to indicate the position of the object on the chart corresponding to a real world position of the object, wherein the sonar beam footprint presented on the chart is different than generated sonar imagery from the sonar return data.
