Integrated mapping and audio systems
View Patent ↗An integrated position mapping system and an integrated sonar mapping system both permit recording, storage and playback of audio data. Audio data is provided to the integrated sonar mapping system or the integrated position mapping system so that it may be correlated to position data or echo data. The integrated sonar mapping system includes a sonar transducer for emitting and receiving sonar signals that may be subsequently be processed to provide echo data from objects in the water which reflect sonar signals. The integrated position mapping system includes a position receiver for providing position data. A controller not only processes the data for storage, but also correlates the audio data to echo data or position data. The correlated data may therefore be retrieved for playback of the audio data and display of the position data or echo data.
