20040423: reading non-McIDAS files into McIDAS (cont.)

Hi Paul,

Do you have any documentation for the "raw" GVAR files that your
Quorum ingest system is producing?  I have been looking through
the McIDAS GVAR server code and am getting a feel for it, but I 
need to know how the data it serves -- raw data from an SSEC
GVAR ingestor -- compares to your data.

Thanks in advance...

DirectMet works with the raw data ingested by the Quorum system?

Me too.

Yes, it may well be possible.  Some information on the format of the
raw data ingested by the Quorum system would be most useful at this moment.

>Both Quorum and DirectMet "file" images with type .gvr but of course I  
>have no idea if we have any "raw" GVAR images anywhere on our system.   

Joe says yes.

And get some documentation on the data.  If the gvar file that Joe
provided is really raw, then the data that the McIDAS GVAR server
works on is not really raw, or at least not totally raw.

I was thinking about FSU being willing to operate an ADDE server
that would be open to the community.

Accessing satellite imagery is not like MP3 files. The geek factor
is significantly higher ;-)

One thing at a time...

Very cool!

OK.  Did you call?  If yes, did you learn anything?

Having an ADDE server for the data would fit IDV nicely as well.

Cheers,

Tom
