I used this wonderful library when I need to answer how close the airplanes were over my head for safe UAS operations on the ground. This was near an uncontrolled airport (no tower) so the airspace and general legal limit was 400 ft AGL but I recorded aircraft as low as 175 ft AGL on their down wind leg of the landing approach. The tool gathered ads-b data from the aircraft using an rtlsdr, then let me plot it on Google Earth for analysis. Was really useful to me at the time and a fun way to learn a little about GIS. https://gitlab.com/btreecat/bstokml https://gitlab.com/btreecat/bstokml
