Solved it: the first time the script is run it saves the Color Interp and
Descriptions in the .aux.xml within the zip, and the output image remains
Undefined for these fields. In subsequent runs saving the aux fails, and the
output image fields for Color Interp and Description are filled out. As I've
been using the same input archive repeatedly while testing this sequence was
being masked.
So now I'm at the crux I think: how to tell gdal.Translate() to use these
metadata without applying them to `data_in.GetRasterBand(1)` and saving first?
Is there a more efficient method than:
~~~
data_in = gdal.Open(vsipath)
gdal.Translate(dstname, vsipath, width=w, height=h, ...)
data_out = gdal.Open(dstname)
data_out.GetRasterBand(1).SetColorInterpretation(gdal.GCI_RedBand)
data_out.GetRasterBand(1).SetDescription("Red (0.625 - 0.695 microns)")
...
data_in = None
data_out = None
