Hello I have the following results from a side scan sonar (in M/S word format), the scan was done some time back to locate items from a wreck in the sea.
I don't know how to read the results and need some help starting with Click Position .
Is the Click Position, the position of the object on the scan or the position of the fish when it captured the image ?.

Click position: Probably refers to the position of the mouse arrow that was placed on the possible target. Google "click position" and you will get a sense of what they mean by "click position". The side scan towfish would be in the center position of the display and off to one side would be the target. By placing the mouse pointer over it would provide the position of the target.

Hope this helps. Cheers, Jim

If this data was collected with a towed array there would need to be a layback entered for the position to be correct.
