[McIDAS #BJT-176673]: Question about displaying the Satellite Image On McIDAS-X

Hi,
re: what was the IMGDISP output when you ran the command above?

> * See the First Attachment Image with the following command code:
> IMGDISP G13/VIS27APR11 1 DAY= 11117 TIME= 1902 2045. .  (Snapshot 4)

The output shows that the way that the time was specified (TIME= 1902 2045)
was incorrect.  Recent versions of McIDAS expect time to be specified
as HH:MM:SS (or HH, or HH:MM).  Given this, the IMGDISP invocation
would be:

IMGDISP G13/VIS27APR11 1 DAY= 11117 TIME= 19:02 20:45

Also, this invocation will display as much of the image as will fit
in the frame using the default load of:

- upper left of the image being in the upper left of the display frame

- magnification (MAG= ) of one

Try the following IMGDISP invocation instead:

IMGDISP G13/VIS27APR11 1 DAY= 11117 TIME= 19:02 20:45 MAG=-4

This will load every 4th pixel in the horizontal and vertical from
the original image.  If the problem was that the upper left hand
corner of the image is off in space, this should show some sunlit
pixels in the lower right.

re: did you try displaying images for other times of the day?

> See the Third attachment image with the following command code:

Again, these loads will display the upper left corner of the image
in the upper left corner of the frame.  Adding a MAG=-4 will
likely result in the display of sunlit pixels which are in the lower
right (lower -> more southerly; right -> more easterly).


re: try IMGLIST G13/VIS27APR11 DAY=11117 TIME=1902 2045 FORM=ALL

My bad.  The IMGLIST invocation should have been:

IMGLIST G13/VIS27APR11 DAY=11117 TIME=19:02 20:45 FORM=ALL

re: it would be most useful if you could send one or two of the
images that result in blank IMGDISP displays.

> *The blank IMGDISP is embedded in the snapshots shown earlier.*

I meant attach one of the actual image files to your reply.  Also,
it would be a lot quicker for me if you cut and pasted output text
into your email reply instead of doing screen captures (both work;
inline text is faster for me).

re:
> *My Linux files setup might be of use to you.

Unfortunately, this was not useful.  Getting an actual file would
be of use.

re:
> Hope I provided you with adequate help to solve this problem.

I think that the first problem is the incorrect specification
of the time range in the IMGDISP invocation.  If this was
done from the command line (McIDAS Command and Text window),
then the problem is easily fixed; see above.  If it was done
from the SSEC GUI (which is shown prominently in your snapshots),
then the problem is a bug in the GUI code that I will need to find
and fix.

re:
> Thanks alot of your rapid response by the way.

No worries.  Sorry my follow-up was a lot slower.

Cheers,

Tom
