Feature request: add button to Metadata Viewer to fill metadata for conventional products

[aloboa]

Manually filling metadata is tedious and, in most cases, many images share the same metadata.
A button to add conventional metadata for eg the different kinds of Landsat, ASTER, EnMap, Sentinel images
(or even letting the user provide a csv file) would be very useful.

For conventional sensor product, we have special Import Algos that will take care of proper metadata assignment:

or even letting the user provide a csv file

We now support STAC-like sidecar files for providing metadata. Maybe that is what you need (?)

@jakimowb in the GDAL Metadata widget, we have the option to Paste Metadata:

I'm not really sure how that works. From where would I copy the original metadata?
What is the format... a table, a json-dict?
Is that feature documented?

Yes of course, I know that. But in many cases, the user has an image (eg a Landsat image) that does not come from your Import tool. In those cases, adding the conventional metadata at once would be useful.

What I need is a way to write those files. For example, how do I create a GDAL PAM file out of hdr file?

@jakimowb in the GDAL Metadata widget, we have the option to Paste Metadata:

I get the Paste option always greyed, even if I select Copy metadata first...

I understand, but I guess that we won't take the time for such convinience function.
@jakimowb any thought on that?

You can't do this in the GUI.
You have to use GDAL API to do it. Just ask ChatGPT: "How set band metadata with PyGDAL."

Hmm, you are right, looks like a bug.
@jakimowb please have a look at this.
