Re: [idvusers] ISL to save satellite data in McIDAS format

Robert-

This server has been in the list of available servers in the IDV Image Chooser for many years.

Robert replied to me that the answer I gave him (the NESDIS Public server) 
would work. Unidata should be aware of this. It has been available for many 
years now. Please update your info in regards to this server.

I do not know if this helps your particular case but NESDIS offers a public 
ADDE server that has full res GOES imagery in AREA format as well as 6 hourly 
Meteosat, MTSAT, and India SAT. The data set is PUB and the server is 
SATEPSANONE.NESDIS.NOAA.GOV

Thanks for the response Tom.

Since I don't meet the university requirements and need realtime data
on a scheduled basis, I'm probably going to have to go the Jython
route. Are there any examples of how to do this? I'm fairly proficient
in Python/Jython, but not sure what classes / methods I should be
looking at for this.

Hi Robert...

Okay, now I understand why you need the GVAR nav.  Fact is, the GINI
images are re-projected at the data source before being sent on
NOAAPort.

If you are affiliated with a University, then there is a Unidata
server available that has high-rest GVAR images; otherwise, you would
have to contract with SSEC to get realtime GVAR data from our servers.
If you don't need realtime data, you might look at NCDC and see if
the CLASS data would meet your needs...last I looked they did provide
data in AREA format as one of the options.  See
<http://www.ncdc.noaa.gov/oa/rsad/satfaq/class-goes-read.html> and
<http://www.class.ncdc.noaa.gov/saa/products/search?datatype_family=GVAR_IMG>

Finally, you probably could re-project the TANC-nav data by getting an
AREA file that has the desired GVAR navigation and then from Jython,
resample the TANC-nav data into it.

Hi Tom,

I'm using the file in the ARPS model, and it expects the AREA file to
have GVAR navigation.

When I run a.getNavigation() on the GINIEAST images, they show
navigation as being TANC, and the files fail in ARPS. However, the
images in the RTIMAGES stream show a.getNavigation() as being GVAR,
and these files work. Would it be possible to get the GINIEAST images
into the same navigation / etc (not real familiar with satellite file
terminology) as the files in the RTIMAGES stream?

I'm not sure what your issue is with the navigation.  I did the two steps:

a = af("adde://adde.ucar.edu/imagedata?&PORT=112&COMPRESS
=gzip&USER=idv&PROJ=0&VERSION=1&DEBUG=false&TRACE
=0&GROUP=GINIEAST&DESCRIPTOR=GE1KVIS&BAND=1&LINEL
E=2560 2560&PLACE=CENTER&SIZE=854 854&UNIT=BRIT&M
AG=1 1&SPAC=1&NAV=X&AUX=YES&DOC=X&POS=0")

a.save("/temp/test.area",0)

I then went back to the file chooser and read this file in as a McIDAS AREA file
and it displayed just fine....

What am I missing?

Finally got around to implementing this, and apparently the data has
to be in the GVAR navigation format. The images in the RTIMAGES stream
work, but I would prefer the GINIEAST stuff which has a higher
resolution (for visible) and is updated more frequently. Is there a
way to convert from TANC to GVAR? Or is there another stream that
provides the GVAR data at higher spatial / temporal resolution?

I was reading in a previous email in the Unidata archive that this
could be done in McIDAS, but I don't have access to that. Is there a
method / function available in the IDV (via Jython) that would do
this?
