Chapter 4: Making a DTM with BathyPro
What BathyPro Does
The purpose of BathyPro is to process single-beam and multibeam data,
resulting in an output of DDS_VIF files or DXF files that can be imported into
DelphMap as a digital terrain model (DTM).
In the course of using BathyPro to produce your DDS_VIF files or DXF files you
can:
• process and smooth navigation
• remove “spikes” or “glitches” from the motion sensor data
• process and edit the bathymetry data from multibeam, interferometric or
single beam sensors
• build a digital terrain model (DTM)
• extract depth contours
• generate a soundings chart in DXF format
• extract XYZ data to go into an ASCII file
• calculate volume differences between two DDS_VIF files
• Patch Test. BathyPro also contains a patch test utility (Chapter 7, ‘Running
a Patch Test’
) having its own set of internal functions. With patch test you
can:
•
automatically calculate pitch, roll, yaw, latency and velocity parameters;
•
display 2-D color-coded data, which can be corrected with offsets that act
as a confidence check with computed corrections;
•
respond to operator-supplied coarse and fine adjustments as small as 0.01
and 1 millisecond;
•
show each iteration of the patch test process using a least-squares
computation
To run BathyPro and provide files to the program to use
1. Double-click the program named BATHYPRO.EXE or its icon.
Your initial BathyPro Editor display resembles the screen shown in Figure
