Re: [gdal-dev] gdal_translate drops XMP exif tags
Thanks Even and everyone! As a workaround I think that for each XMP tag=value in the input .jpg, I can specify '-mo tag=value' option to gdal_translate. It appears that those tags/values are embedded and preserved in GDALMetadata through subsequent gdal processing. E.g. I can specify the following options to gdal_translate: % gdal_translate -mo Pitch=1.3 -mo Roll=5.5 -mo Yaw=192.1 Then downstream tools can get Pitch, Roll and Yaw from the GDALMetadata tag.
