Oops sorry, I got lost a little in all the previous messages. I bet
thought that the problem you may be seeing is due to the fact that
Image data comes in as connections based data. If you are
Rubbersheeting the TIFF, then this could be the problem. Try putting
a Post right after the ReadImage to change it to 'positions'
dependent data.

David,
Either I'm not following you or I haven't conveyed clearly what I'm doing.
The grid that I create has the same resolution as the TIFF. My original
message was slightly inaccurate - what I do is Construct a grid (with dummy
data) then use Replace twice to transfer its positions and data to the TIFF
field. The result of this is a regular field with colors, in the same frame
of reference as the elevation data, but with the TIFF resolution. I then
Map elevation data onto this field. The image at this point displays
perfectly. The final step of RubberSheeting makes the image go bad, but I
found that simply adding an AmbientLight fixes it up.
Just to be certain, I tried Refining the elevation data before Mapping it,
but this made no difference.
If anyone is interested I could email a sample of the screwy image.
