5.1.4 Geometry Settings

There are two options here for
vessel offsets: either pole/hull
mounted; or towed configurations.

Vessel Mounted: Offsets can
be read directly from the raw
XTF data file if it was
entered during acquisition.
Alternatively the

Create

button allows the user to
enter the vessel offsets and
generate a vessel geometry
file, and the

Load

button

allows users to load a vessel
geometry file already created.
Shown right is an example of a
vessel geometry file. In
addition to measured vessel
offsets, this is where the patch
results are entered.

Multipliers: if the pitch or
heave was already corrected in
real-time, then the multiplier
needs to be set = 0; also some
heave sensors use an opposite
sign convention from Triton with
negative pointing down (for
Triton z = + down), these need the multiplier set = -1.

Towfish Configuration: For towed interferometric sonars producing bathymetry
data, it is possible to apply typical sidescan layback options.

Vehicle Depth: Note that both options above will compensate for the sonar depth
based on pressure data if this box is checked.
