Layer Properties
The Layer Properties dialogue box is accessed from the
shortcut menu in the Echogram and Numerical views.
Purpose
This dialogue is used to edit the properties for the active layer.
Layers are used to calculate various values for a specific range
in the water column. The calculated values can be displayed in
the Numerical view. All single targets detections which are
displayed in the Single Target Position view and the Single
Target Histogram view are detected within a layer.
Limits
Start Relative Surface / Start Relative Bottom - This
parameter controls the depth at the upper boundary of the layer,
relative the surface or detected bottom depth depending on the
selected layer type.
Range - This parameter controls the vertical depth range for the
layer. Please note, positive is always downwards. This means
e.g. that a start range relative bottom of -10 m means 10 m
above bottom.
Type
Surface - The range settings for the layer are referenced to the
surface. The layer is downwards limited by the detected bottom
depth if this value is shallower than the specified lower range
limit for the layer. Pings without bottom detections are ignored
in the calculations.
