[McIDAS #CNA-970101]: METEOSAT 10 Imgcopy problem

Hi Heather,

As you will have seen, I moved this email into our inquiry tracking
system...

re:
> I am having a problem with my METEOSAT -10 Visible data. We get this
> data in real-time from NESDIS.

Are you accessing the METEOSAT-10 imagery from a NESDIS ADDE server?  If
yes, which one?

re:

OK.

Hmm... Using McIDAS-X v2014 I just displayed a BAND 1 VIS image directly
from the ADDE server at EUMETSAT (a server for which one has to have specific 
permission to access), and then IMGCOPYed it to a local image and displayed
the copy.  I had no problem with either the direct display (IMGDISP) or
display of the copied image.

Questions:

- have you tried doing the IMGCOPY from a McIDAS-X session?

  If yes, what was the result?

- could I get one or two of the images in AREA file format you got from
  EUMETSAT so I could test them here?

re:
> I have attached a pptx to illustrate the issue.

Just so you know: it would be easier for me if you would send a screen capture
(use the McIDAS FRMSAVE function) instead of a Power Point file.

re:
> Have you encountered this problem before??

No, I haven't.

re:
> Do you know a fix?

As soon as I can test one or two of the AREA files you got from EUMETSAT,
I should be able to say more about what may be going on.

re:

A cursory scan of your Python scripts doesn't reveal anything obvious.

OK.  Hi Mary Ellen!

re:
> We appreciate any help you can offer!

Send me one or two AREA files you got from EUMETSAT, and I will test them
in both McIDAS v2014 and v2009 and let you know my results.

Cheers,

Tom
