Well you can also get the data by exploring the zone and then going to the maps section in net-7 portal, but it doesn't show hidden navs, and it only shows navs a given character has explored.
Another way to go is once explored it, target all the navs and hit control-T on them to get their coords, then log out and extract it all out of your chat log text file.
Again, I've got the data, and/or have ways to get what I'm missing. At this point its more of putting in the effort to just finish the project.
