The application presented here shows live air traffic over parts
of Northern Switzerland and surrounding Central Europe.
The major goal of this project is to demonstrate how traffic
data can be efficiently visualised in real-time and in 3D by
combining state-of-the-art tools MATLAB and Google Earth.
The air traffic data displayed are collected by an ADS-B receiver (Automatic Dependent Surveillance Broadcast) on
one of the buildings at ZHAW Zurich University of Applied
Sciences, School of Engineering, Winterthur, Switzerland.
The receiver that collects the raw data of the airplanes was developed by Marcel Rupf (ZSN) and his group. The well known application
http://radar.zhaw.ch/, which was initiated and designed by Karl Rege (InIT) and developed as part of a diploma thesis at ZHAW, makes use of the same data.
There is a huge variety of other data (static or dynamic), from various fields, which can be visualised with Google Earth.
In many cases the adaptation / extension of the framework
developed in this project is quite straightforward.
While you are running this application, disable all layers, except: borders and labels, terrain, and 3D buildings.
To prevent the airplane text become too dominant on the screen, set the label/icon size to small as follows: Select Tools in the GE menu, choose "Options" and set "Labels/Icon Size" to small within "3D View".
Hide the sidebar to see the maximum area/airspace.
Screen shots and movies
To demonstrate some of the capabilities of the tool we provide several screen shots and movies below. Please note that the image resolution of the movies is reduced (in comparison to the original) due to file compression.
By navigation in this context we mean that you (the observer) can move virtually through the 3-dimensional space.
Besides well known standard operations with the mouse (e.g., rotation of the earth), there are two options to
navigate in GE:
(1) by using the navigation elements on the top right of the screen (if active), or
(2) by using the scroll wheel of the mouse together with some specific buttons on the keyboard.
We recommend to use the second option, as it allows more precise and often faster navigation.
Altitude above sea level
Mouse scroll wheel
Heading: angle of line of sight relative to north,
e.g., heading towards east is 90 degrees
CTRL + Mouse scroll wheel
Tilt: angle between the line of sight and the vertical,
i.e., the line perpendicular to the earth surface
SHIFT + Mouse scroll wheel
Forward relative to current heading
ALT + Keyboard arrow ↑ (up)
Backward relative to current heading
ALT + Keyboard arrow ↓ (down)
Left relative to current heading
ALT + Keyboard arrow ← (left)
Right relative to current heading
ALT + Keyboard arrow → (right)
Note that by additionally pressing the ALT button, the first three movements listed above become a lot smoother.

Various aviation related links
Live air traffic over parts of Switzerland with Google Maps, developed at ZSN/InIT of ZHAW, best known as the "radar" project.
The application is written completely in MATLAB (release 2009b) and runs on an ESXi 4.0 server with operating system LinuxCentOS 5.4. The kml files generated are in accordance with KML version 2.2. The 3D airplane model was drawn
with Google Sketchup 7 (Credits to Patrick13 for providing the basic version of the Airbus A340-300 model).
Remo Maurer (Head IT, SoE) for providing invaluable support with the Linux server and for getting it running!
Daniel Kramarz (InIT) for hints on connecting to the web service (raw data).
