The Paths for Processing Single-Beam Data
Single-beam data also can be processed in automatic (batch) mode or in
interactive mode.
In the automatic (batch) mode, or path, of processing single-beam data,
bathypro.exe again is the program to use. Each module within the larger
BathyPro application performs processing specific to single-beam data.
Chapter 6 explains how to use BathyPro in automatic mode to process
single-beam data this way.
In the interactive mode, or path, of processing single-beam data, you use a
program called sbeam.exe, instead of processing your data with the
bathypro.exe program. Chapter 6 explains how to use BathyPro in
interactive mode to process single-beam data this way.
Data Input for Either Type of Processing
The data input to BathyPro can be in a number of different formats:
• Raw data — stored in XTF format
• Pre-computed X, Y, Z data — stored in ASCII text files
• Grid data — in the form of a DDS_VIF file
For any BathyPro project (DTM file), the file list can only contain one of
these types. Consequently, you cannot mix XYZ, XTF, and DDS_VIF files
(data sets) in the same project.
For each type of file the BathyPro menu will be different:
• When importing an ASCII file, navigation, attitude, bathymetry editing and
speed velocity correction are not available.
• When importing a grid file, the BathyPro menu will propose a set of filtering
algorithms and contour extraction values.
Data Output for Either Type of Processing
The output of BathyPro can be three types of files:
• Raster graphic files containing the DTM (DDS_VIF)
• Vector graphic files containing the contour data (DXF)
• XYZ ASCII files also are exportable.
The first two file types can be imported directly into DelphMap.
