A cheap solution although somewhat involved. The freeware Mr. Sid viewer
can export .sid to .tif and by default writes a .tfw and .tab file at the
same time. You can, of course, delete the .tif image and then edit the .tab
file in notepad to point back to the .sid image and while you're there enter
the correct projection parameters. It also has an option to reduce the
resolution of the image during export and does an admirable job in case you
don't want to deal with gigabytes of hi-res data for a large area. For
those using ArcView too but without the ArcPress rasterizer extension, you
can bypass the .sid printing bug in v3.1 and v3.2 by exporting to .tif with
the MrSid viewer.

Subject: MrSid, from ArcView, *. SDW georeferenced images to
MI
I currently have a set of georeferenced MrSid DO's prepared for use
in ArcView with the extension *.SDW. projected in NAD83 in feet, State Plane
Mich. South
MI 5.5. will read MrSid files but requires to the best of my
knowledge re-registration or so does the "big book" suggests (page 303).
This defeats the purpose of the exact DO's registration. Has anyone tackled
this one, and if so how?
Any input/contributions will be much appreciated.
Sincerely,
