Hi Nathan
Unfortunately there is not ColorInterp for NIR or RedEdge. But you can use
the "Description" of the bands. QGIS will use that name. I do not know how
to do it in gdal_merge (I did in C++).
About computing the NDVI, as far as I know there is no trick to do it in
the "Layer Styling". If a
I have individual TIFS from the different sensors on the drone. Currently, I
have the R, G, NIR, and Redge bands. Is the correct method to merge these into
a multi-band image that I can then view as NDVI or apply other algorithms
against just to use:
gdal_merge.py -separate R.TIF G.TIF NIR.TI
