Thank you Bob. To be clear, I should pass "w8" as a single flag together as opposed to "w" and "8" as an additional?

I will also try the GraphixMagic tool and report back! Does it have any dependency on tiles vs raster/line? Is the approach I take to write the data suitable?

By the way, where can I find the latest official LibTIFF release that supports BigTIFF? I should be sure I'm using the right version. It seems there are a variety of links out there that point to old content and "page not found"

Unfortunately, the web site domain has been lost a couple of times already. These are the two official pages:

   http://www.simplesystems.org/libtiff/
   http://libtiff.maptools.org/

The simple answer as to what version of libtiff is required to support BigTIFF is that libtiff version v4 or later is required.

All that should be necessary to enable BigTIFF is to pass the additional flag "8" in the open flags string to TIFFOpen() or TIFFClientOpen().

Unfortunately, the page at http://www.simplesystems.org/libtiff/man/TIFFOpen.3tiff.html does not appear to be updated to include the above.
