5.1. Mean Altitude
5.1.1. Overview
From Seanet Pro V2 onwards, there is facility to calculate a mean altitude
value from the Profiler data points of a single or dual head scan. Data points
from the Master, Slave or both heads in a dual head pair can be applied in
the mean altitude calculation.
The mean altitude (or mean seabed) calculation will include only seabed
coverage and not trench coverage that falls within the Profiler scan coverage.
For this scan coverage, the scan size and position can be adjusted using the
direction and width controls on the RAT controller. A typical dual head Profiler
arrangement will be as shown in Figure 5.1, “Dual Head Profiler Example”.

Note
The
Mirror Slave
Profiler control is enabled in order to achieve
the above direction and scan packet orientation. This control will
counter the scan direction of the slave with respect to the master
Profiler.
Several rules have been set to distinguish seabed from trench coverage.
There is also a filter that will remove spurious profiler points from the
calculation.
There are several options and parameters that can be applied in the mean
altitude calculation. These are configured in the
Mean Altitude
setup
