GeoTIFF tags found in TIFF files used as input in IMAGINE may be removed from the output file written to GeoTIFF format.
The TIFF specification allows for non-standard (private) tags to be added. The specification does not address how these tags are managed. IMAGINE also introduces non-standard tags, some known as citations. TIFF tags that are not identified as standard tags in the TIFF specification are not preserved in the TIFF output created by IMAGINE. This may create an issue when another software vendor has a vested value in the presence of these non-standard tags.
