Chesapeake Times, Vol 8 | January 2022Getting Started with SonarWiz If you are new to SonarWiz and purchase at least one new SonarWiz license, we want to make you and your team comfortable using it. New for 2022, we offer a complimentary 2-hour Zoom session to get you started. The session covers installing and licensing SonarWiz and a brief tutorial on using SonarWiz to process a sample data set. During the class, we answer as many SonarWiz questions as time allows. Up to 5 people can participate in this Zoom session, to be held during our normal business hours, 9:00am – …
Large File Handling in SonarWiz
Chesapeake Times, Vol 3 | October 2020 In the next version of SonarWiz, we added a few options to help folks with large files. We have seen the ever-increasing file sizes, as folks collect higher resolution data or just more data. Days of 8-bit sidescan and single beam echosounder have been replaced with 24-bit sidescan data and multibeam sonar. With each update, file sizes are larger, and sometimes, unmanageable to move from one machine to another, or take much, much longer to process. We have added in a few new features in the latest update to address this issue. Tool …
Applying Antenna Elevations SonarWiz
Chesapeake Times, Vol 6 | July 2021 When real-time kinematic (RTK) corrections are available in the survey area, it is possible to achieve sub-decimeter vertical positioning of the sonar system without the need to apply tides or vessel squat measurements. Bathymetry collected in this way is referenced to the satellite ellipsoid rather than to the more conventional orthometric or tidal datum, so it is usually required to apply a vertical transformation to move the bathymetry into the desired output datum. SonarWiz has all the tools needed to perform these calculations in a straightforward workflow. Navigation and Attitude Editor The first …
Adding Tides & Starting Elevation to Sub-Bottom Data
Chesapeake Times, Vol 6 | July 2021 New for SonarWiz 7.8.0 – we are adding the ability to utilize Tide data to correct Sub-Bottom sonar data. In addition to Tide data we are also adding a Starting Elevation value for each Sub-Bottom file. This will allow the user to specify the elevation for the survey. SonarWiz Sub-Bottom data has several sources of Elevation data and Depth data: These data add together to describe where the sonar is located vertically. In other words a Vertical Offset of the Sub-Bottom sonar data. This information together with the travel time will allow a more accurate location for …
Updates to Gains in 7.07.05
Chesapeake Times, Vol 5 | April 2021 In SonarWiz 7.07.05 we will be introducing several changes to the sidescan and sub-bottom gain dialogs to make them easier to use and to support a new workflow for EGN. We’ve also removed an undocumented normalization step in gain processing that dates back to the 8-bit era of SonarWiz. Taken together, these changes may affect how your processed data looks, especially if you stack gains to achieve a particular effect. We hope that the changes make it easier to understand how gains are being applied to your data. A bit of SonarWiz HistoryUntil …
Enhancements of Sub Bottom Profiler Modules
Chesapeake Times, Vol 2 | July 2020 Among the changes scheduled for the upcoming 7.7 release of SonarWiz are a number of improvements in the SBP modules. Several exciting features are in the development and testing pipelines to aid in the importing, processing and interpreting workflows – things like automated import from a monitored folder, assisted reflector tracking, multiple detection, and improvements to alignment to bathymetric surfaces. In this article, though, I’d like to talk about a couple of simpler improvements in the SBP modules, particularly in the processing window. These improvements have been in the works, and conditionally available or …
