[McIDAS #XAM-728083]: RTGOESR No Navigation...

Hi Christian,

re:

You caught me right as I was reviewing some User Support inquiries :-)

The similarities and differences in these two sources of GOES-16 imagery has
caused a lot of consternation in the community!

The only other thing that I can think of is the navigation information
for the frame(s) in your session is not being written to a subdirectory
of the hidden ~/.mctmp directory.

Questions:

- who are you running imgdisp.k and map.k as?

- what is your McIDAS environment when you try to run the commands?

What is the result of:

ls -alt ~/.mctmp

re:

No.  The navigation information for each frame is written into a subdirectory
whose name is the shared memory segment handle when a McIDAS-X session
is run (and a session is created for single command invocations in the
same way as it is for a full interactive session.

Please try the following:

<as 'mcidas'>
cd $MCDATA
mcenv -f 1@1000x1500

imgdisp.k RTGOESR/CONUSC01
map.k
frmsave.k 1 test.gif

exit

Running both imgdisp.k and map.k in a session created by mcenv will
insure that the navigation information written to the subdirectory
of ~/.mctmp will still exist when map.k is run.

Cheers,

Tom
