When Autopano encounters a tif file with GPS coordinates / altitude information embedded in the photos used to create a panorama, it would be nice if you would include that infomration in the final image file metadata.
I know that the info might vary slightly from one photo to the next, but just pick the data in the first photo and use it.
We already do that. If the first image that has metadata contains GPS coordinates, it is transfered as it to the final panorama if the format of the final panorama does support metadata. We support tif and jpeg. PSD/PSB does support metadata but we don't know how to transcast from exif to XMP yet.
