I need help setting up a model to batch perform "NNDiffuse Pan Sharpening". I have 10 multispectral Landsat images and 10 panhromatich landsat images after Dark Susbtraction process. I want to loop through each 2-image set (multi, panhromatic) and generate a pansharpening output. I tried to do this using 2 datasets, 2 iterators, generate filename, and NNDiffuse Pan Sharpening. I get the error "Nodes cannot be traced back to more than one iterator: [NNDiffuse Pan Sharpening]. What is the correct way to set this up? I want it to run like: Run 1: multi1, rpanhromatic1 are used to generate pansharpening1 Run2: multi2, rpanhromatic2 are used to generate pansharpening2 etc... Thanks in advance!

You would need to set it up with an iterator and an extract elements from array to pass the two sets of rasters in parallel. For example: low res rasters->iterator->Extract elements from array (enter as Indices to extract) ->NNDiffuseSharp (from iterator) high res rasters->extract elements from array (enter as Input array)->NNDIffuseSharp (from Extract elements of array) Does this work for you?

Yes, it works. Thanks a lot! But I have another problem :) I try to do a big model and I can not connect PanSharpening with Dark Substraction Correction. My model looks like bellow: multispectral rasters -> iterator -> radiometric calibration -> raster statistic -> dark substraction correction ->agregator -> iterator -> NNDiffuse PS -> -> panchromaticl rasters -> iterator -> radiometric calibration -> raster statistic -> dark substraction correction ->agregator -> Extract Element -> NNDiffuse PS -> -> This both model are connecting by NNDiffuse Pan Sharpening. But when I run model I get the error: "Parameter INPUT_HIGH_RESOLUTION_RASTER faild validation: Value must be a scalar ENVIRaster". Could you please help me with this?
