Background
Google Earth's data files (KML) allow for loading 3D models and other customizations in to the Google Earth environment. Newer versions support limited animation and timeline control capabilities. However, these new capabilities are too limited for accurate aircraft accident visualization. Google also provides a browser plugin and API for controlling a Google Earth scene from within a web browser via JavaScript. Below are proof-of-concept applications that allow playback of an accident sequence in the Google Earth environment. The playback shows progression of the flight path synchronized with recorded audio.
Note:
- All Browsers - Aircraft models sometimes do not display initially. Zooming within the GE view with the mouse usually causes the models to appear.
- All Browsers - Loading the audio completely can take 10-30 seconds or more on an average Internet connection. There's currently no progress indicator.
- Firefox (PC & OSX) - In firefox, if you use the timeline control to skip forward or backward, then the transcript text will become out-of-synch with the audio.
Demo 1
In this accident the primary aircraft had just taken off. He came disoriented in congested airspace over Newark airport before crashing. Two commercial flights were in close proximity at the time of the accident.
- Demo #1 - Requires GoogleEarth plugin. You will be prompted to install it if you do not have already have it.
- KML File - This is the underlying KML file in the demo and can be loaded in to the standalone GoogleEarth program.
- Video Screencast - A short screencast. Useful to get an idea of demo's functions or if unable to view the live demo.
Demo 2
This demo shows a longer flight path. When the accident aircraft detected engine problems, he begain a search for nearby airports. However, due to the night time conditions and city lights, he had trouble finding the closest airports.
- Demo #2 - Requires GoogleEarth plugin. You will be prompted to install it if you do not have already have it.
- KML File - This is the underlying KML file used in the demo and can be loaded in to the standalone GoogleEarth program.
- Video Screencast - A short screencast. Useful to get an idea of demo's functions or if unable to view the live demo.
