I have a side-question concerning the update-in-place behavior of the gtiff driver in this case: given that a compressed strile will nearly always be smaller after this update (due to better compression ratios on the uniform area), will libtiff overwrite the previous strile in place also, or will it be appended to the existing file (resulting in a larger final file size)?
If the updated tile/strip occupies a smaller size than its previous version, it will overwrite in place. Note however that it will not wipe out the bytes that are no longer used, which might potentially be an issue in the context of censoring. Thus I would recommend doing a final gdal_translate to get a "clean" version before distributing it.
