ADSB visualizations via Pi and RTL-SDR

Photograph showing two JAL flights flying close to each other.

I used a raspberry pi and RTL-SDR to capture ADSB data from my home and while out and about to build a picture of aviation activity around me.

The application also features several declutter algorithms and tools to show different datasets depending on

Route commonality
Altitude
Date/time
Velocity
