This tool can be used to find the minimum value in each cell of a grid from a set of input images. It is therefore similar to the MIN operator in the Whitebox GAT Raster Calculator, except that it is capable of accepting more than two input images. It is found within the Overlay and Multi-Criteria Evaluation (MCE) toolbox.
NoData values in any of the input images will result in a NoData pixel in the output image. The output raster is of the float data type and continuous data scale.
The following is an example of a Python script using this tool:
wd = pluginHost.getWorkingDirectory()
# You may have multiple input files but they must
# be separated by semicolons in the string.
inputFiles = wd + "input1.dep" + ";" + wd + "input2.dep" + ";" + wd + "input3.dep"
outputFile = wd + "output.dep"
args = [inputFiles, outputFile]
pluginHost.runPlugin("MinOverlay", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
// You may have multiple input files but they must
// be separated by semicolons in the string.
def inputFiles = wd + "input1.dep" + ";" + wd + "input2.dep" + ";" + wd + "input3.dep"
def outputFile = wd + "output.dep"
String[] args = [inputFiles, outputFile]
pluginHost.runPlugin("MinOverlay", args, false)
