We created a route from SCEL (Santiago de Chile) to EHAM (Amsterdam) via around 60 beacons/waypoints. The site you linked works great and actually does have a few beacons that we use in our route so I can use those tracks. However still not all of my tracks are covered, I can post them here, but it's a LOT of work to do..
Thanks for now! I'll compare the tracks that I got from the link!
