I wanted to give notice about a tool I have been developing over the last years, which I recently extended to be able to import/analyse/visualize Air Traffic Surveillance data, i.e. from Radars, ADS-B, tracking systems etc.
If you are interested, you can find the project page at:
github.com/hpuhr/ATSDB

I also created a few YouTube videos:
Installation, Import & OSGView
OSGView Display Options
Labeling, Highlighting and Filtering
Thank you guys for an awesome library!.
