"Within the remote sensing, and photogrammetry community the 4GB limit is becoming significant already"

This was an issue that came up in the ISO task force working on TIFF/IT-P2.

Does anybody on this list have a sense of how important the file size limit is in graphic arts applications? (I can't see anyone doing remote sensing using TIFF/IT!)

it's important for us. we manipulate image files for film recorders. at the limit, they can do 3000 dpi. for a 22 by 33 inch print, that's 22 * 3000 * 33 * 3000 = 6534000000 dots = 6534000000 * 3 = 19602000000 bytes = 19.6 GB uncompressed. i think. that would be exceptional, but not unachievable.

I assume (from the '* 3') that you're talking RGB contone, and therefore colour film recorders rather than imagesetters here.

I will admit that I had not expected anyone to use TIFF/IT rather than normal TIFF for that kind of work - am I wrong?
