Hi Owen,

I grabbed the GMS-5 and GOES-10 images you made available by FTP and
verified that there is a problem using the McIDAS v2002x IMGREMAP
to combine the images.  I went out to the SSEC MUG inquiry web site
and found out that others have experienced problems with IMGREMAP
when MERGE=YES is specified.  I tried downloading the most recent
code from the SSEC CVS and used it to build a new IMGREMAP executable
which I then used in the same tests you provided.  The results were
that the problem still exists in the new code.

I did find out that you can use the McIDAS 7.8x version of IMGREMAP
with v2002 with no apparent problems.  You can do this in two different
ways, both of which must be done as the user 'mcidas':

1) copy the 7.8 version of the IMGREMAP executable to the v2002
   ~mcidas/bin directory

2) make a backup copy of the v2002 IMGREMAP source; copy the 7.8
   IMGREMAP source to the v2002 src directory; and remake the
   the IMGREMAP executable

Option 1) is probably the easier way to make the change, so I recommend
that you use it:

<login to the machine that Hsie built McIDAS on as 'mcidas' and do the
following; I include instructions for Solaris and Linux since Hsie had
things a little different on those platforms>

Solaris:

cd solaris/bin
mv imgremap.k imgremap.k.2002
cp ~/mcidas7.804/src/imgremap.k .

Linux:

cd linux/bin
mv imgremap.k imgremap.k.2002
cp ~/mcidas7.8/src/imgremap.k .

>Thanks!

Sorry for the problems.  Hopefully, a fix for the problem will be developed
by SSEC and made available before the next McIDAS release.

Hi Tom,
It worked!
Thanks,
