[Datastream #SXB-674928]: GOES East West imagery...



Hi Gilles,

re:

Very good.  Also, your comment about using the GEMPAK plugin suggests
that you are using the IDV for display.  Please let me know if I am
misinterpreting this.

OK.  The NOAA CLASS system should have all of the satellite imagery
that exists, and one can get those images in AREA file format.  The
areal coverages will be greater than the sectors that were sent in the
UNIWISC datastream of the IDD, so the data sizes will be much greater.

OK, good.

OK, it is important to understand the time constraints you/your student is
facing.

OK.  This is also an important thing to know.

Unfortunately, no, not in the time frame that you described above.

re:

Hmm...  The process of creating the composites should be reasonably simple
once the GOES-East and GOES-West image sectors are in-hand.

Here is the message I send to all non-U.S. universities who inquire about
getting access to Unidata McIDAS:

Unidata has long been licensed by the Space Science and Engineering Center
(SSEC) of the University of Wisconsin at Madison to distribute our version
of McIDAS, Unidata McIDAS, to educational institutions.  In the recent past,
SSEC refined their definition of allowable use of McIDAS at institutions
outside of the U.S. and for individuals.  Users from non-U.S. educational
sites are typically recognized by their email addresses not ending in '.edu'.

I am required to have prospective McIDAS users read and agree to the following:

  SSEC considers permissible users of the international university community
  to be those who are using McIDAS-X for academic classroom instruction or
  academic research by students related to obtaining a degree. Research 
institutes
  and government agencies that use McIDAS-X for meteorological research or
  operations must purchase a license from SSEC for the non-academic use. Given
  this clarification, and if Unidata users remain within the licensing terms
  that include no re-distribution of any portion of the software, SSEC is 
agreeable
  to providing this software to the international university Unidata user 
community.

Given the above position, we need a clear statement from you that specifies
_all_ of the following:

- you are accessing McIDAS from Unidata for use in a university; please provide
  the name of the department and university that the download is intended for
- McIDAS must be used for academic classroom instruction or academic research
  by students related to obtaining a degree
- your installation of McIDAS is not for use by a government agency, 
non-academic
  research institute, or private concern
- you agree that you will not re-distribute any portion of the software

As soon as you state that your use of Unidata McIDAS will conform to the
terms listed above, we will add the email address:

<xxxxx>

to the list that allows downloading of Unidata McIDAS.

We can only add your email address to the list of users allowed
to download McIDAS if you are registered with the Unidata website
under that address. If you are not yet registered with our site,
please do so before sending back the reply to this message.

I apologize for the difficulty in getting access to Unidata McIDAS-X,
but our hands are tied by our licensing restrictions.

re:
> Thanks for your time and help,

No worries.

Cheers,

Tom
