Travel. Simulation. OpenStreetMap, les routards du web #1 : A la carte ! «Comment peut-on passer de 100 000 à un million de contributeurs ?» C'est l'une des questions ambitieuses qui ont été débattues, ce week-end à Amsterdam, dans le cadre du State of the Map 2009. Pour la troisième édition de son grand meeting annuel, le projet OpenStreetMap veut sortir de l'ombre. OpenStreetMap , sorte de Wikipédia de la cartographie, est un projet un peu fou qui tente depuis 5 ans de redessiner le monde sous Creative Commons, rue après rue.
Sa communauté œuvre d'abord par idéologie. Convaincue que les données géographiques de la planète devraient appartenir au bien commun et non aux agences qui les ont relevées pour les exploiter commercialement (Ordnance Survey au Royaume-Uni, IGN dans les pays francophones...), elle encourage les internautes à effectuer leurs propres tracés et à les publier sous licence CC by-sa .

Many large datasets contain data that describes the relationship, or connection, between two or more entities contained within the data set, and many tools are now available for plotting graphs and network diagrams when presented with data that has been structures in a suitable manner.
(A graph is a mathematical structure that can be used to describe these connections in a formal, and easily represented way. In a graph, 'nodes' are connected to each other by 'edges' in either a directed way (a link that goes from one node to another, but not vice versa, such as "A is the parent of B') or an undirected way (the relationship is 'symmetrical' - the M1 motorway connects Leeds to London, and equally connects London to Leeds).) For example, the IBM Many Eyes visualisation toolkit has a network diagram visualisation that will plot when presented with a set of paired data elements. Here is a map of the internet, circa 2003 that shows the connections between different internet routers. Early adopters vs the Mainstream: Google Insights points out web. Intro to Google InsightsI have recently been playing around with the insanely useful Google Insights for Search product.
You should definitely try it out if you haven't. It's basically Google Trends on steroids, and shows you a ton of data on any search you try. An SEO wizard's dream, basically. It's described as: With Google Insights for Search, you can compare search volume patterns across specific regions, categories, and time frames. Basically you put in keywords and it give you pretty charts. Navigation searches and geo-locationOne useful query to try is to search for your favorite website - like "gaiaonline.com" and specifically target it towards the US.
Although unscientific, it tells you a bit about the location of the people who use the website, since logically the folks in states where the product is popular would tend to search for it quite a bit. This is exactly what I've done below... The graphs for Digg, Facebook, MySpace, Netvibes, Skype, Techcrunch, Twitter, and YouTube.
