This tool can be used to find cells with undefined flow, i.e. no valid flow direction, based on the D8 flow direction algorithm. These cells are therefore either at the bottom of a topographic depression or in the interior of a flat area. The user must specify the name of the input digital elevation model (DEM).
The following is an example of a Python script that uses this tool:
wd = pluginHost.getWorkingDirectory()
demFile = wd + "DEM.dep"
outputFile = wd + "output.dep"
args = [demFile, outputFile]
pluginHost.runPlugin("FindNoFlowCells", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
def demFile = wd + "DEM.dep"
def outputFile = wd + "output.dep"
String[] args = [demFile, outputFile]
pluginHost.runPlugin("FindNoFlowCells", args, false)
