HI jeff,
that sounds good. I'm familiar with DODS/OpENDAP, although not with
ADDE. Since I"m familiar with the former my tendency would be to move
forward with that and not with ADDE, but perhaps an expert on both
protocols might prefer a different approach, so feel free to offer
opinions :).
In terms of facilitation, advice is always welcome, what I do know, is
that I don't know how much I don't know. Certainly, there are two
classes of problems, the first is simply setting up a system that works
at all. Presumably DODS will work for that without much hassle.
Second, is setting up a system that could work for a large user base.
That's tougher. That might also require more resources on my end in
order to make that happen, so a grant might be in order. So I'd like
to try rolling it out in a small way, see what the drain is
resource-wise and then think about how to roll this out globally.

Hi Matt,
I have cc'd the IDV head developer, Don Murray, on this as well in
case he
can add/clarify/correct any information.
The "nifty" interface utilizes ADDE servers to offer up this data.
ADDE is part of the McIDAS package and delivers projection and
navigation
information re the dataset. The IDV can also access DODS/OpENDAP
servers.
I think it would be great to offer the live stream via one of these
protocols for IDV use!
Please let us know how we can help facilitate this.
Cheers,
Jeff

Hi folks,
I'm going to ask a question from the opposite end :) I'd like to
serve Level II data to IDV users, using that nifty interface, i.e.
browse to a server and see what they have.... What protocol are those
data servers serving the data out over, and what software are they
running to do this? I'm looking for a more open approach than LDM (I
mean open in the sense of not having to have a strict peer-to-peer
streaming arrangement). Depending on the potential number of clients
I
could potentially serve the national stream in real time...

hmmm, that sounds like a powerful and clean, but slow to implement
solution. I am plainly ignorant of how the server side works, so
forgive my questions. But it seems that the Level III interface could
be leveraged. Simply go through the hoops for the in the GUI for the
Level III data, and then have another box that says "would you like
this as Level II data?" then it's just a matter of a server-side
resolve to a different file name, which IDV more or less knows who to
read immediately.
If it resolves to a non-existent file it exits cleanly.... am I
dreaming? :)
