antonio,
<p>what sensor/instruement was used to record your 'band interleaved (by
scan line)' data.&nbsp; 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.&nbsp; do you know the dimensions
of the detector, the data type used to store, the number of spectral bands?&nbsp;
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 :-)

I did a little digging and it looks like your 'bil' filetype might be
proprietary or an in-house creation. Here is a link to a somewhat
exhaustive (or so they claim) of filetype extensions.

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
