CHAPTER 6: Processing Single-Beam Data
Unlike the earlier chapters in this book which dealt with processing multibeam
data in BathyPro, this chapter is limited to a discussion of how to process single-
beam data.
Starting with BathyPro version 1.00.028, BathyPro now has the ability to process
single-beam echo sounder data recorded in an XTF file. Single-beam data
should be recorded in one or more of the auxiliary data channels (AUX 1 to
AUX6). Typically the data from a dual-frequency sounder would be parsed using
the Isis® Sonar serial data template as 1 (AUX1) and 2 (AUX2).
However, it is also possible to edit and process single-beam data recorded in the
primary towfish altitude (the normal fish altitude channel), or as the secondary
towfish altitude (template token a).
As noted in the ‘Getting Started With BathyPro’ chapter, there are two methods
of processing single-beam data in BathyPro:
• Automatic mode. This uses BATHYPRO.EXE to edit the data non-
interactively. In this mode you enter a window size around the mean depth;
values falling outside this window will be rejected. BathyPro then processes
the data and generates a DTM.
• Interactive mode. In this mode you use a new utility called
SBEAMEDIT.EXE to interactively select the editing parameters using a
graphical interface. The editing can be Full Manual, which gives you full
control of all editing. The degree of manual control ranges from a Stop on
Detection feature, which halts the processing when a user-specified
threshold is exceeded, to Auto Correction mode, which automatically edits
any data that exceeds your settings.
The following is a brief description of the steps needed to process a typical XTF
file using either method.
Automatic Mode Processing Using BathyPro
Automatic mode has the virtue that you can set up all your parameters at one
time, quickly process the data under program control, and end up with a valid
output file.
