Hi Greg, re: > I'm using McIDAS in a field project application where I'd like > to overlay the flight track of the G-V over the current satellite > image.

I did find a previous support question that > suggested the PATH command may be what I need however, when I click on > PATH in the command list(commands by alphabetical order), I get a > "File Not Found 404 Error". Can you point me in the right direction? Thanks for finding out that the link to the PATH command was bad. I have corrected it now: https://www.unidata.ucar.edu/software/mcidas/current/users_guide/PATH.html The other thing that could be used is McBASI, the McIDAS Basic-like interpreter. McBASI (instantiated in the RUN command and extensively documented in the McIDAS Users Guide) has a 'plot' capability. 'plot' can draw lines between points in the TV coordinate space. In order to use 'plot' I would write a McBASI script that: - reads Lat,Lon pairs from a input file - converts each Lat,Lon point to a TV coordinate - uses the 'plot' capability to plot on the display Do you have a file of aircraft locations that I could take a quick look at?
