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

How to utilize sat feeds with open data? Across ADS-B track data (like OpenSky Network) South America, Africa and Oceania seem covered in addition to Europe and America, as does East Asia, and India. But China, and some parts of Central Asia and Middle East appear absent?

A lot of people running SDRs send beacon info upstream on the internet.

I have had no problem accessing ADSB data for various parts of Asia.

Nice find! The GitHub repo near the top of that thread is great, too: https://github.com/ClickHouse/adsb.exposed
