antonio,
<p>what sensor/instruement was used to record your 'band interleaved (by
scan line)' data. as you probably know, .bil is not a detailed file
format standard, but a general description of the orientation of spectral
and spatial dimensions in spectral image data. do you know the dimensions
of the detector, the data type used to store, the number of spectral bands?
with that information it one might proceed with some expectation of quick
success.
<p>in the absence of information, try the following
<p>- look for an associated header file or 'more' the data file to see
if there is text header information.
<br>- dig into the file, read it in byte/int2/... pieces to look for repeating
patterns which you might recognize as bands... hope for simplicity...
<br>- before digging though i'ld go to the source of the data file for
information.
<p>good luck, george

You might check this link...
http://www.erdas.com/support/faq/images/erdas7xfiles.pdf
Starting on page 3, they talk about the format of a .BIL file. I don't
know if it's the same as your .BIL but it might be :-)

Can you drop some more details? Are you just trying to read a raw .bil
file? .bil is not very descriptive by itself. Is there header info
involved? Do you know what program wrote the file?

Shoot. I wish I knew the answer to your question.
But somebody will, probably. :-)
Cheers,

Hello again.
I think you are absolutely right. My anonymous posting was not very polite,
but I can assure it was not premeditated. Hope this will help.

I don't know the answer to the question, as it happens,
but I do know a bit about the psychology of newsgroups
and I can assure you that the chance of getting an
answer to a question increases dramatically if you
offer your name. :-)
> Many thanks in advance.
The thanks is nice, and helps, but not nearly as much
as a name. Anonymous posters who don't offer thanks,
of course, have a snowball's chance in Hell unless
someone is feeling really, really generous (which
doesn't happen much with today's full employment). :-)
Cheers,
David
