Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.
TeleGeography’s 2012 Submarine Cable Map depicts the world’s major active and planned submarine cable systems.
If the internet is a global phenomenon, it’s because there are fiber-optic cables underneath the ocean. Light goes in on one shore and comes out the other, making these tubes the fundamental conduit of information throughout the global village. To make the light travel enormous distances, thousands of volts of electricity are sent through the cable’s copper sleeve to power repeaters, each the size and roughly the shape of a 600-pound bluefin tuna.Once a cable reaches a coast, it enters a building known as a “landing station” that receives and transmits the flashes of light sent across the water. The fiber-optic lines then connect to key hubs, known as “Internet exchange points,” which, for the most part, follow geography and population.
As a result of participating in the prototyping weekend conducted during UPSingapore, I was able to massage and mangle a number of datasets, graciously made available by private and public organisations. One of the datasets that I managed to sink my teeth into was the collection of geocoded cab data collected over a 24 hour period on the 15 of May 2012 for 15,694 cabs.
From the data, I was hoping to observe the behavioural patterns of cabs in Singapore.
Redrawing the map of Great Britain from a network of human interactions Do regional boundaries defined by governments respect the more natural ways that people interact across space?
This work proposes a novel, fine-grained approach to regional delineation, based on analyzing networks of billions of individual human transactions. Given a geographical area and some measure of the strength of links between its inhabitants, we show how to partition the area into smaller, non-overlapping regions while minimizing the disruption to each person’s links. We tested our method on the largest non-Internet human network, inferred from a large telecommunications database in Great Britain.
Our partitioning algorithm yields geographically cohesive regions that correspond remarkably well with administrative regions, while unveiling unexpected spatial structures that had previously only been hypothesized in the literature. We also quantify the effects of partitioning, showing for instance that the effects of a possible secession of Wales from Great Britain would be twice as disruptive for the human network than that of Scotland.
