I've created a web app for querying and visualization of ADS-B datasets: https://adsb.exposed/

Source code: https://github.com/ClickHouse/adsb.exposed/

The results significantly exceeded my expectations because the pictures are insanely beautiful, and the data is a treasure trove.

It proves many statements that were not certain: - it is feasible to generate tiles by aggregation on a pixel level (instead of hexagons or rectangular grid); - it does not require JPG/PNG tiles - we can transfer raw bitmap data with zstd compression; - it is possible to do it in real time;
