We read location data through netcdf files. I am not sure what the 
format is though. I am pinging a colleague
on this who might know.

The real issue is access to the datasets in a form that the IDV can 
read. You might want to check with
Chuck Meertens (who works with the IDV on the GEON project) 
address@hidden
and ask him if any of those data sets are available.

The "globe idv" shortcut is outdated. Its purpose was to bring up the 
IDV in 3D "Globe" mode.
The current cersion of the IDV allows one to bring up a Globe display 
through the File->New->Displays
menu.
