I have a set of tif files generated from a process with multiple steps. Some metadata tags are added at different steps. I would like to update the metadata of those file before distributing the files. Using gdal_edit.py -mo, I can add some new lines in the metadata, but I would like to remove some the old lines (internal tags that we use for quality control).
Is there a way to clean the metadata and/or update some of the tags ?
