Abstract: A system for the display of radar returns is provided. The system comprises a radar configured to provide radar data, a processor, and a display configured to present the radar data. The system comprises memory including computer program code configured to, when executed, cause the processor to receive the radar data, wherein an object is represented within the radar data; receive additional data from a data source other than the radar; and determine object characteristic(s) of the object using the radar data and additional data, wherein the object characteristic(s) comprises a position, a velocity, an intensity, or an object classification of one or more objects. The computer program code is also configured to cause the processor to cause presentation of the radar data including a representation of the object and an indication of the corresponding object characteristic(s). A marine electronic device and a non-transitory computer readable medium are also provided.

Abstract: Various implementations described herein are directed to a non-transitory computer readable medium having stored thereon computer-executable instructions which, when executed by a computer, may cause the computer to receive sonar data from a transducer assembly. The computer may process the sonar data to detect occurrence of an event and, in response, may automatically generate a waypoint corresponding to the event. In some cases, the waypoint may be stored with a corresponding sonar image or other information.
