Q. How can I visualize the sidescan sonar data from an SBD file?
A. Sidescan sonar data that is stored in an NaviScan SBD file is imported into NaviEdit but cannot be visualized in NaviEdit.
The NaviEdit report includes more information regarding the sidescan data.
The visualization of sidescan sonar data is done in NaviModel.
- Import the sidescan data via the NaviEdit node in the NaviModel project tree. The user have the option to normalise intensities, which we would recommend.

- Once imported, go to the DTM and right click and create an intensity surface.

- Then go to the properties of the DTM and set Intensity for the Color mode.
Figure 3 How to display the intensity surface
If you don’t want side scan draped onto the DTM surface, go to the DTM's properties view, and set its surface type to Flat.
The surface type and the side scan will stay at 0m depth.

If you don’t want side scan draped onto the DTM surface, go to the DTM's properties view, and set its surface type to Flat.
The surface type and the side scan will stay at 0m depth.
Additionally, you can control the Gain by right-clicking on Intensity under Colour Modes
