I will follow this with interest, particularly the ADS-B bit. We have a chain of receivers running along South Africa’s N3 highway for about 500km. If anything they show how few aircraft are equipped with ADS-B! I love your little traffic screen at the bottom left. Filtering on that would be excellent, http://radar.3dronemap.com:9090/VirtualRadar/desktop.html We have to have the ability to add in whatever other electronic conspiquity method comes along, as ADS-B is well, pants 
Great work well done.
