Replaying Saved Sonar Files

Replaying Saved Sonar Files

When SonarView is operating "live" with one of the supported devices, you may elect to save the data to be replayed later. Note that this is not automatic, but there is a "Record" toggle available in each of the device controls. When this is enabled, all data will be saved to your user's Documents folder, or to the location you have specified in Session Configurations.

Clicking the Open Log File button on the home screen or icon in the top right opens a file dialog with which you may select previously saved SonarView log files.

When the file is opened, SonarView will automatically detect the type of sonar from the data in the file and will open the appropriate view module. The Replay controls will be displayed at the left side of the window.

• File Position control will set the position in the file so you can go back to view a particular selection

• Play/Export Range allows you to specify the range of the file that gets exported

• Time-Based Playback replays data in the original time domain of the recording. When disabled, replay occurs in the ping domain at a fixed pings-per-second rate

• Replay Speed In Time-Based Playback, Replay Speed acts as a multiplier of the original recording time. In non–time-based (ping-based) playback, Replay Speed specifies the number of pings per second

• Export provides several options for exporting the selected portion of the log in various file formats

The Display Controls are displayed on the right sided of the window. These vary depending on the device. Here for example are the Display Controls for the Omniscan 450.
