TPE Settings: The Total Propagated Error (TPE) for each sounding is written into
the Generic Sensor Format (GSF) file when it is created.
Shown below is an example of the TPE settings dialog using a R2Sonic sonar.
It’s important to check these settings to verify the correct sonar is selected. If
your sonar is not listed, choose a similar sonar and select
View Sonar Device
which
allows the user to change the values and save to a new custom device name.
NOTE:
When processing bathymetry data in Perspective, in addition to the grid
layer that is the selected output of the process, a GSF file is also created for
each input survey line. The GSF file contains sounding data fully corrected for
navigation processing, vessel motions, and applied offsets. In addition to the
depth and position, each sounding also is assigned a TPE value based on the
values entered in the settings using the CUBE library to determine the total
propagated error from all sources.
