摘要：A system for determining distance corresponding to positions within a sonar image is provided. The system includes transducer elements configured to transmit sonar signals into a body of water and receive corresponding sonar returns. The system further
includes a device with a processor and a memory including computer program code that is configured to cause the device to receive sonar returns, generate sonar images based on the sonar returns, receive a user input selection indicating a first and second sonar position in the sonar images, determine a first chart location that corresponds to the first sonar position, determine a second chart location that corresponds to the second sonar position, determine a distance between the first and second chart location and cause the distance to be displayed on a user interface. Systems are also included herein for presenting sonar beam indicators on charts for noting the direction of the sonar beam.
