Bug Fixes
The latest release of SonarWave Lite includes a couple of bug fixes.
- If the XTF file only contained sub-bottom data it would load but not display the image data. This has been fixed in the new release.
- If the XTF file contained different range or sample values between pings the viewer would report an error and exit. This bug has been fixed in the new release.
Incremental File Loading
A new feature with SonarWave Lite includes the option to incrementally load an XTF file. This option has been added for computers that may have hardware limitations loading large files, and users who simply want to load XTF data in smaller sections.
The updated viewer includes an option to set the maximum number of pings that can be loaded at one time. The default setting is 10000 pings. This can be increased or decreased according to the users preferences. If a file has more pings than the above preference, a dialog box allows the user to drag and select the ping range to load in the viewer.

Choose Pings dialog box
To select a range of pings to view, simply click and drag. the start and stop pings are displayed below the selection bar. After the file is loaded a new button
for loading additional pings is active in the toolbar.
Additional pings can also be loaded from the View menu. Selecting either the button or the View menu option will bring up the Choose Pings dialog where the user can select a new range of pings to view.

Introduction
The r.in.mb GRASS/Mb-Stystem program is designed to import mbio compatible multibeam data directly into the GRASS GIS.
The program is a modified version of r.in.xyz. Instead of reading an ASCII XYZ file, r.in.mb reads an MB-System compatible list file as shown below.

Introduction
The SonarWave Lite software, a free program developed by Tekmap Consulting, is an innovative tool designed for viewing Extended Triton Format (XTF) file. You can view XTF sidescan files with low or high frequency channels and also sub-bottom profiles.

SonarWave Lite with XTF file loaded
The SonarWave Lite software is written in C# for the .NET framework. The software is built to run on a Windows® XP or Windows® 2000 operating system. Because the software is written in .NET it may run under newer versions of Mono (untested).
The SonarWave Lite software has not been tested on The Windows® Vista platform.
SonarWave Lite Features
The features of SonarWave Lite include:
- Detecting automatically and prompting users with available XTF channels (i.e. high/low frequency sidescan and sub-bottom).
- Providing two views of the loaded XTF file, with a smaller “Full Image” view and a zoomed view in the main window.
- Displaying file information for open XTF sidescan files.
- Adding range lines to help locate features and estimate distances on XTF sidescan files.
- Drawing bottom tracking, if recorded, for port and starboard sidescan channels.
- Using Zoom features to enlarge or reduce details on XTF files.
- Viewing XTF files in grey, blue, and sepia colors.
- Inverting the colors on XTF files.
- Using the Gamma and Equalize features to enhance XTF files.
- Saving XTF sidescan files to PNG images.
- Providing embedded Help documentation.
These features are described in greater detail with the embedded Help documentation. The features are also described in future postings.
Download
The SonarWave Lite software is available for download as freeware. The software is provided as a Microsoft Installer (.msi) format. The installer file includes the main program, supporting library, and documentation. The installer will test for the correct version of .NET.
