Acoustic PSU

Defines the AcousticPSU process data, linking strata, acoustic PSUs and EDSUs.

DefineAcousticPSU(
  processData,
  UseProcessData = FALSE,
  StratumPolygon,
  StoxAcousticData,
  DefinitionMethod = c("Manual", "EDSUToPSU", "DeleteAllPSUs", "PreDefined",
    "ResourceFile"),
  FileName = character(),
  AcousticPSU
)

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.

StratumPolygon

The StratumPolygon process data.

StoxAcousticData

StoxAcousticData (defined in RstoxData).

DefinitionMethod

Character: A string naming the method to use, one of "Manual" for manual tagging of EDUSs to PSUs; "EDSUToPSU", which sets each EDSU as a PSU; "DeleteAllPSUs" to delete all PSUs; "PreDefined" to read from a previous process; and "ResourceFile" to read from a project.xml file from StoX <= 2.7. Note that in the latter case it is assumed that the contents of the project.xml file is actually used in the StoX <= 2.7 project, i.e. that UseProcessData = TRUE in DefineAcousticPSU().

FileName

The path to a resource file from which to read PSUs, in the case that DefinitionMethod is "ResourceFile". Currently, only a project.xml file from StoX 2.7 can be read. Must include file extension.

AcousticPSU

The AcousticPSU process data.

Value

An object of StoX data type AcousticPSU.
