Rajul,

Currently, the NIDS and NOWrad (tm) radar products require a subscription
to WSI Corporation.  The NIDS products will become freely available in
the December timeframe.  The NOWrad products are, however, created ty
WSI, so they will continue to require a subscription.

Yes, you can FILE the products directly.

>2. Can I view satellite images in GEMPAK without installing McIDAS?

Yes.

No, you only have to have McIDAS-X installed if you need to build the
ldm-mcidas suite of decoders.  If you can use one of the binary distributions
that we make available, then you do not need to install McIDAS-X.

>Thanks for all your help,

Since I perceive that you really don't want to install McIDAS-X, and since
it is most likely that you will be able to use one of our binary ldm-mcidas
distributions to decode imagery from the Unidata-Wisconsin (MCIDAS feed
type) datastream, I will hold off on sending you the McIDAS-X access
information for now.

Hi Tom, 

Thanks for the help. You were correct, for now at least I didn't really want
to install McIDAS; I was just planning to look at Sat imagery in GARP at
least until later in the year when I had more time to install McIDAS.
Anyway, I looked at the email list for ldm-gempak and found a message you
wrote to Columbia, Missouri about the exact same thing. I followed the steps
you suggested and it works great; I was just looking at GOES-10 Water Vapor.

Anyway, thanks for answering my questions this morning and setting me along
a very fruitful search. I really am impressed with UNIDATA in general; the
web resources are excellent and when I needed more help I got prompt and
patient help. 

Thanks, 
Rajul
