Satellite imagery, elevation models and robust GIS mapping methods are utilized to create a vegetation model, terrain model and ground clutter (3D buildings). Of all available audio tracks, only two are used, La Guardia Tower and New York TRACON Departure controller position. Radar data as well as the onboard Flight Data Recorder are utilized in constructing the flightpath of the aircraft.
