Are you doing all of this as the root user?  I see that everything
here is owned by root, and writable only by root as well.  If you're
then trying to run the script as a normal user, they won't be able
to modify the files.

As far as case, any case will do, whether it's all small letters,
all capital letters, or any combination.  You merely have to make
sure that the filename inside the .inf file matches the image
filename EXACTLY.

If so, then the script should work.

Right there it tells you that it couldn't find the filename listed
inside the .inf file.  Check the spelling and case.

The script takes the first part of the filename:  "SCANDI-S1", then
tries to make a .geo file called "SCANDI-S1.geo" and uses the
filename inside the .inf file to run ImageMagick's "ping" command
against in order to figure out the size of the image file.  If the
filename inside the .inf file doesn't match the real gif or jpg
file, then ImageMagick won't find it, and you'll not create a valid
.geo file.

I suspect that the filename inside the .inf file does not match the
image file you have.  Does it say "scandi-s1.gif" inside the .inf
file, or does it have some capital letters or a mis-spelling?

Nope.  Those are mostly useful inside the U.S.  Check the
README.MAPS file for places to download maps.  There are a lot of
choices, both in types of maps and in places to download them.  I
prefer vector maps for streets/world maps, and raster files for
topographic features.

Nowhere that I know of.  You can snag lots of .inf maps though and
convert them to .geo files.  Once you figure out how to correct .inf
files that are wrong (like the one you have above), you'll do fine.
Files from Windows/DOS machines often have incorrect case matching,
because on those operating systems it doesn't matter and it hides
the problem.  On Unix/Linux, you see the problem that exists.
