Javier,

You can run the LDM on another computer- but will also need to run the GEMPAK
decoders from the LDM on that machine. You can run GEMPAK on any other machine
that NFS mounts the decoded data locations. GEMPAK does not provide any
other mechanism for remotely opening data files.

The satellite image formats that GEMPAK and McIDAS use are AREA files
from the case studies (GEMPAK can also read GINI format satellite images). 
These files contain all the image navigation necessary
to project and display the images. Gif files are only for browsing. They
do not contain any navigation information for GEMPAK or McIDAS to use.

You can download AREA files from the case studies. You can view these in NSAT
by using the "User Defined" file browser to open the file for viewing.
If you don't have the $SAT tree set up, you should define $SAT to point 
somewhere so you
can launch the application, such as setenv SAT /tmp.
