Hi all - I am trying to run a land classification in ArcGIS Pro that uses information from both a 3-band RGB orthomosaic and a 1 band nDSM with elevation data to classify the landscape. I have combined these bands into one raster layer (using the composite bands function) but when I collect training samples from this composite band layer, it seems like those samples are only using data from the RGB bands and not the elevation band. The attribute table for the samples only displays data for Red, Green, and Blue.
I am wondering if:
1) the training samples ARE collecting elevation data to incorporate into the classification and I am just not seeing that
2) there is a different approach I should be taking here
I have tried to troubleshoot in a few ways - for instance, projecting the nDSM band into band 1 so it's visible while I am collecting training samples (the layer's symbology is currently displayed as RGB) and collecting training samples from the original nDSM layer (i.e. not composite bands, only one elevation band), but I still cannot see elevation data being collected in the training.
Thanks in advance.
Abbey
