This function defines the Strata associated to different surveys (in the sense that a separate estimate should be made for those strata).
DefineSurvey(
processData,
UseProcessData = FALSE,
DefinitionMethod = c("AllStrata", "Table", "ResourceFile"),
StratumPolygon,
SurveyTable = data.table::data.table(),
FileName = character()
)The current data produced by a previous instance of the function.
Logical: If TRUE use the existing function output in the process.
Character: A string naming the method to use, one of "AllStrata", which defines all strata as the same survey named "Survey"; "Table", which requires the SurveyTable to be given; and "ResourceFile" to read from a project.xml file from StoX 2.7.
The StratumPolygon process data.
A table of the two columns Stratum and Survey.
The path to the StoX 2.7 project.xml file to read StratumPolygon from, in the case that DefinitionMethod is "ResourceFile".
An object of StoX data type BioticPSU.
Acousic PSUs are generated using DefineAcousticPSU. For the vertical resolution (Layer) see DefineBioticLayer and DefineAcousticLayer.
