The ENVI command, Binary Raster by Automatic Threshold, works pretty well. For the ENVIBinaryAutomaticThresholdTask, the documentation states the output is a binary raster file that for a mask. However, in an ENVI API script, I get the error message that the mask raster must only have one band. Sometimes the layer manager shows the output file with a single band, other times in the data manager, it has three bands. I assume the three bands are for each of the three input bands. So do I need to use band math with relational operators or is there a setting that I am missing? https://www.nv5geospatialsoftware.com/Support/Forums/aff/218/aft/8247/afv/topic Anonymous Tue, 19 Mar 2019 06:05:15 GMT https://www.nv5geospatialsoftware.com/Support/Forums/aff/218/aft/8247/afv/topic 5 Hello, does anybody find that the surface fucntion (when the /fill keyword is added) can not work.
