DefineAcousticLayer: Define Acoustic Layer

In StoXProject/RstoxBase: Base StoX Functions

Define Acoustic Layer

Description

This function defines the AcousticLayer process data, which sets the range intervals of the acoustic layers used in acoustic-trawl estimation models in StoX.

Usage

DefineAcousticLayer(
  processData,
  UseProcessData = FALSE,
  StoxAcousticData,
  DefinitionMethod = c("WaterColumn", "HighestResolution", "Resolution", "Table"),
  Resolution = double(),
  LayerTable = data.table::data.table()
)

Arguments

processData	The current data produced by a previous instance of the function.
UseProcessData	Logical: If TRUE use the existing function output in the process.
StoxAcousticData	StoxAcousticData (defined in RstoxData).
DefinitionMethod	Character: A string naming the method to use, one of "WaterColumn", to define one single for the entire water column; "HighestResolution", to use the maximum possible vertical resolution without intersecting hauls; "Resolution", which can be used to set a fixed layer thickness; and "Table" to provide the LayerTable.
Resolution	Numeric: A single numeric giving the thickness of the layers.
LayerTable	A table of Layer name, MinLayerDepth in meters and MaxLayerDepth in meters, defining the Layers.

Value

An object of StoX data type AcousticLayer.
