I have included answers to your questions below. Overall, I think we
need to know if (1) our data will meet your needs, (2) your mission
involves research and/or education. If you think that our data is
indeed useful to you, please provide us with a description of your
mission and how you would use the data. This will help us evaluate what
kind of data we might be able to provide to you.
Please see below for more information.

Thank you for your answer.
I understand the LDM is freely available, but as access to the IDD is to the
best of my knowledge restricted, I assumed that you could download LDM to
set up your own "instance" of IDD, if you know what I mean, and access to
the IDD was not to be taken for granted, even though you could have LDM
Yes, that is correct that you can do what you like with the LDM but are
not guaranteed IDD participation.
IDD access depends on a couple of things. The most siginficant issue is
that we are somewhat constrained on relaying international data by WMO
Resolution 40, see
http://www.nws.noaa.gov/tg/control.html. However, WMO Resolution 40
allows redistribution for the purpose of education or research. For
example, degree-granting institutions are granted exceptions to this
constraint. We need to know if research and/or education is within your
Other than that, IDD participation would depend on finding a site in our
community that is willing to feed you data. That, in turn, would depend
somewhat on what type of data you want or how much data you want to get.
It would help if you could make a compelling case for how you plan to
use the data.
The software that drives our IDD network is the LDM. The LDM
code is freely available - anyone can get it and use it.
However, you must be a member of our community to get
That's interesting, what does it take to become a member ?
Let's break down the term "member" into two parts: participation in the
IDD, and getting support. I addressed participating in the IDD above.
Regarding getting support, from our Participation Policy page at
"Unidata provides direct support via email for its software packages to
institutions offering college-level courses for credit, and to
non-profit institutions with education or research missions."
I understand that you are a non-profit organization. Again, do you have
either an education or a research mission?
We have these requirements because we are funded by the National Science
Foundation, http://www.nsf.gov/, and thus must follow their rules.
Also, in general, it is our expectation that once IDD participants get
up and running then they can support themselves for the most part or get
support through the community venues. This is because we are a
relatively small group with limited resources. We do, however, have a
strong community with members who support each other well, so that is a
very viable resource.
There are also some other sources that might be
able to help you install and support the software such as the
on-line documentation and the ldm-users email list. Please
see our Participation Policy for more information regarding
the software license and support:
Do you just want to use the LDM software to relay your own
data, or is it the case that you want to participate in our
IDD network and get some of that data? If it's the latter,
which data sets are you interested in?
At first, we would use the LDM to gather some data. However, we do not
exclude to relay data on the IDD at some point in the future.
We are interested in any GIS data related directly or indirectly to natural
For instance, we're always after meteorological data, satellite imagery,
sismologic data, and the like.
The IDD does not currently relay any GIS data per se. (By "GIS data"
I'm thinking of ESRI shapefiles, for example.) Generally our data is
either raw or processed for visualization in a variety of packages
designed for atmospheric analysis. It may be the case that you would
have to significantly process (or reprocess) the data in order to make
it displayable on your maps. Would this work for you? Note that the
LDM provides a generic way to process data, but you would have to
provide the actual processing tool yourself.
I hope this information is helpful. Please let me know if you have any
other questions or comments.
