Patent attributes
Systems and methods for presenting marine information are provided herein. A system includes an array of a plurality of sonar transducer elements associated with a watercraft and a display. The system causes presentation of a chart of a body of water, including a representation of the watercraft at a current location. The system also operates the array to cause transmission of sonar beams into the underwater environment and receives sonar return data from the array. The system further generates, based on the sonar return data, a two-dimensional live sonar image, determines a facing direction of the array, and causes presentation of the sonar image in the facing direction on the chart and relative to the representation of the watercraft. Accordingly, live sonar imagery is presented on the chart to visually provide a relationship between objects within the live sonar imagery and the real-world position of those objects.
