Plotting the World By Airports
There are over 7 billion people on our planet, and that number is increasing daily. With so many people with different travel requirements, it is essential that routes and landmarks are clearly represented on whatever form of plotting system that area of travel has adapted to.

There are over 7 billion people on our planet, and that number is increasing daily. With so many people with different travel requirements, it is essential that routes and landmarks are clearly represented on whatever form of plotting system that area of travel has adapted to. Usually, in most areas of travel, maps are the most common form of visual network representation used and with air travel that is no different.
In plotting all the different airports of the world and all the different flight paths that have been developed over the years, users are able to get a general idea of where the different routes are and locate the main airports, but because of the amount of points to be shown (i.e. 3,275 airports and 37,153 single routes), the points can often get a little blurred and start merging.
However, with the help of Martin Grandjean, you can see an excellent representation of these extensive travel networks. With his creation of the current global network of airports and flight paths, you can see the connections in a much clearer way than most others used today. By using a force-directed layout algorithm, the points are displayed as a magnificent spectrum of colors plotted in 3D and connected accordingly, giving viewers a more realistic picture than a traditional map.
Even though air travel is on the decline, according to recent studies, customers that do travel in this way are generally happy with their airline industry, and we can expect to see more changes in this field coming our way.
