Surface Range
The Surface Range dialogue box is accessed from the short-cut
menu in the Echogram view.
Purpose
This dialogue is used to
specify the vertical depth
range for the
Echogram
view.
Surface or Bottom?
The dialogue title and the
range settings will be surface
related if the dialogue is
opened while the echogram
displays a surface referenced
echogram.
The dialogue title and the
range settings will be bottom
related if the dialogue is
opened while the echogram
displays a bottom referenced
echogram.
Parameters
Start Relative Surface / Start Relative Bottom - This
parameter controls the depth at the upper boundary of the
echogram, relative the transducer face / detected bottom depth.
Range - This parameter controls the vertical depth range across
the echogram view. Note that positive is always downwards.
This means that a start range relative bottom of -10 m means 10
m above bottom!
Apply to all - Check this box to apply the the new range setting
to all current surface and bottom echograms.
