Issue with adsb is that very few outside Europe and the US share their signals, so any app will have partial validity, unless you use satellite feeds.

Last I looked at it coverage is pretty good for land globally? Sea less so.

The bigger issue is that in first world buying a sdr dongle for giggles is viable while in poor countries less so. A raspberry and dongle is a substantial investment if you’re earning 1/20th of a US salary. Don’t think there is an issue with willingness to share data

This is certainly missing some kind of legend explaining the colors of the lines, and what data is actually shown.

Is "red" high or low velocity? And as an example, I do not understand what the "Boeing vs. Airbus" selection is trying to represent, as well as how "Altitude & Velocity" are supposed to be displayed at the same time.

Project certainly requires a bit more care if any discussion should happen around it.

I see you highlight that, but I believe the visualization is designed to be intuitive once you interact with it a bit—no legend stricty needed if you calibrate against what you already know.

Pick a flight you know (maybe one near yer home) and play with the options -- what patterns emerge? Red draws attention, “Boeing vs. Airbus” compares data, while “Altitude & Velocity” combines them. Explore hands-on; discovery often makes insights click better than instructions.

Thanks for posting!

I've recently added more datasets, "Places", "Birds", "Photos", and "You".

Also, a hint - the rectangular selection tool lets you generate custom reports for a location.

We have a an ADS-B receiver at Summit Station in Greenland which we use to track airplanes that produce RFI we see in our experiment. I've considered sharing data (since nobody else seems to have data there) but the feeding instructions always scare me (run this script that downloads a bunch of random crap as sudo... no thanks).

Please just give me a cURL command I can run... (perhaps some services have that, I haven't looked that hard).

ADS-B is easy to receive with an 'rtlsdr' and opensource tools.
