In the past, selecting the “Capture Contact” button on the SonarWiz map toolbar, then clicking on a contact on the plan view, would always bring up the waterfall digitizer for the file selected and scroll to the area clicked on, for subsequent contact picking. There were some reasons for this behavior, as the digitizer often allowed a significantly better view of the target area, and after-the-fact contact edit options were limited. With subsequent plan view drawing and contact editing improvements, though, this restriction has become mostly unnecessary, so people have been asking for it to be dropped. In the upcoming …
Processing Multibeam Imagery in SonarWiz
By David Finlayson, Chief Scientist Multibeam echo sounder (MBES) imagery has improved dramatically in recent years and each new version of SonarWiz has introduced improved tooling for working with these data. Most of SonarWiz’s image processing and targeting tools are now also available for MBES systems. In this article we will take a look at the two different approaches offered by SonarWiz for processing MBES image data. A MBES image differs from traditional sidescan (see Figure 1). Each beam in a MBES is roughly equivalent to a complete side scan channel. To create an MBES image, the portion of the …
