TL;DR of how it works:<p>- Collect some radar samples of aircraft (latitude/longitude/height).<p>- Here we're using samples of a particular flight from SF to Copenhagen from FlightRadar24.<p>- Use CesiumJS to reconstruct the path on 3D globe.<p>- Add satellite imagery, global 3D terrain, and 3D buildings for context.<p>- These can be from any source/standard format. This tutorial is loading these from Cesium ion.<p>You can get the raw radar samples from FlightRadar24 in step 3 if you want to try your hand at visualizing this in other ways.
