This post is in conjunction with my previous post. This image shows world connectivity through the internet. The data is from February 2007 and shows the connectivity from city to city throughout the world. The information gathered by the author, through the DIMES project, shows 89,344 connections (by router configuration).
The DIMES project seeks to “study the structure and topology of the internet.” Here is a link to their website: http://www.netdimes.org/new/
Here is a link to the author’s website and some more of his mapping projects: http://www.chrisharrison.net/projects/InternetMap/index.html
This map from New Scientist shows the interconnected nature of the world’s travel networks. The map is based on cities of 50,000 or more people, with dark spots being the least “connected” and the light spots being the most “connected”. The text associated with the image follows:
“Very little of the world’s land can now be thought of as inaccessible, according to a new map of connectedness.
The maps are based on a model which calculated how long it would take to travel to the nearest city of 50,000 or more people by land or water.
The model combines information on terrain and access to road, rail and river networks. It also considers how factors like altitude, steepness of terrain and hold-ups like border crossings slow travel.
Plotted onto a map, the results throw up surprises. First, less than 10% of the world’s land is more than 48 hours of ground-based travel from the nearest city.
What’s more, many areas considered remote and inaccessible are not as far from civilisation as you might think. In the Amazon, for example, extensive river networks and an increasing number of roads mean that only 20% of the land is more than two days from a city - around the same proportion as Canada’s Quebec province.”
