Triton BathyPro - Manual (Page 71)

TABLE 4. SPD speed correction file format
Depth (meters) Speed of Sound (meters/second)
10.000000 1500.000000
20.000000 1510.000000
30.000000 1520.000000
40.000000 1510.000000
BathyPro will extend the Sound Velocity table to the deepest soundings.
However, it is always good practice to take a sound velocity cast in the
deepest section of the survey area.
At this stage you can either continue with the next stage
(that is, provide parameters for gridded data processing), or
you can choose to have BathyPro process what you have
so far, to test the validity of the settings you have specified.
To continue with the next stage
1. Read ‘Gridded Data Processings Parameters’ to determine what
parameters, if any, you wish to add to the list of parameters you already
have provided to BathyPro so far.
2. Perform the procedure, ‘To process the data in its current form’.
To process the data in its current form
1. From BathyPro’s main menu, choose Bathy Processing → Select
Processings… and click Process in the Select processings dialog box.
The system processes those parameters in your BathyPro project file that
you have earmarked for processing. The result of this first processing of
the data will be a DDS_VIF file which has been corrected for velocity and
tide, and in which bad data has been removed. However, the file will not
have been filled or smoothed.

Figure 35 shows the dialog box you get for a Grid file (a DDS_VIF file) when you
choose Bathy Processing → Select Processings…
