This tool can be used to find cells in a stream network grid that possess parallel flow directions based on an input D8 flow-pointer grid. Since streams rarely flow in parallel for significant distances, these areas are likely errors resulting from the biased assignment of flow direction based on the D8 method.
The output raster is of the integer data type and Boolean data scale.
The following is an example of a Python script that uses this tool:
wd = pluginHost.getWorkingDirectory()
pointerFile = wd + "D8 pointer.dep"
streamsFile = wd + "streams.dep"
outputFile = wd + "output.dep"
args = [pointerFile, streamsFile, outputFile]
pluginHost.runPlugin("StrahlerOrderBasins", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
def pointerFile = wd + "D8 pointer.dep"
def streamsFile = "not specified"
def outputFile = wd + "output.dep"
String[] args = [pointerFile, streamsFile, outputFile]
pluginHost.runPlugin("StrahlerOrderBasins", args, false)
