[IDD #ZKK-809489]: GRB broadcast on iddb still happening?

Hi Pete,

UNIWISC already contains a nice set of GOES image sectors in PNG compressed AREA
format.  The good news (for us, at least) is that it would be very easy to
REQUEST just the "old" sectors, just the new imagery, or both.  For instance:

Old/original PNG compressed AREA sectors:

REQUEST UNIWISC "pnga2area" <upstream feed host>

New/netCDF GRB imagery and products:

REQUEST UNIWISC "cspp-geo" <upstream feed host>


REQUEST UNIWISC ".*" <upstream feed host>

The fact that the old and new images would not be in the same format does not
seem like a big deal to me, but I am all ears if you have a different view!

FNEXRAD currently contains radar imagery (in GINI format, no less).  I am not 
that satellite imagery really fits.

This is an interesting idea indeed.  DIFAX is _one_ of the feed types that needs
to be repurposed along with IDS, DDS, and PPS.  The only hitch would be the need
to cut a new LDM distribution in which the name DIFAX would be replaced by 
like GOESR.  I'll talk this idea up with Mike and Steve!

Reusing something like DIFAX is attractive since it is not in active use anymore
(that we know of, at least).  Since you were the last to use it, it should be
safe to repurpose it for GOESR/S distribution.

More later...
