actually, there is a command line executable for exporting MrSid files to
.tif/tfw files. it's called mrsid_retrieve.exe, and you can probably get
it free of charge from lizardtech if you email them. they were kind enough
to do that for me.
it
takes a little work to figure out the syntax if you export the images out to
anything but a 1:1 pixel ratio, but i've got a little wizard that works with the
executable that will do the trick. if you can get a hold of the executable
from lizardtech (i'm not sure if i can just send you my copy), then i'll give
you the wizard.
i do
exactly what you are describing all the time. sometimes, with thousands of
MrSid images.

Hi all,
I'm working on a project which requires the
converting of over 100 MrSID files into reprojected ECW files. I don't
have any MrSID products other than the free GeoViewer which I've been using to
manually export them into GeoTiff files. This is a fairly slow process
and I was wondering if anyone had any ideas on how to speed it up.
Here's the procedure I'm curretnly using:
MrSID --> GeoTiff ---> Batch Reproject with
ERM --> Batch compress to ECWs
There is no command line decompression for the
MrSID GeoViewer that I could find. I do have access to ArcGIS 8.1, but
the only license we have allows use to compress 50Mb files into MrSIDs, there
are no batch decompression tools that I could find.
Thanks for you help.
