Year of Edits to OpenStreetMap via Video
ItoWorld has posted a video visualization of all the 2008 edits to the OpenStreetMap project, a wiki mapping project taking place across the world. The project depends on individual contributors and the video does a wonderful job of exploring the surges of data from around the globe. ItoWorld describes their video:
This animation displays a white flash each time a way is entered or updated. Some edits are a result of a physical local survey by a contributor with a GPS unit and taking notes, other edits are done remotely using aerial photography or out-of-copyright maps, and some are bulk imports of official data.
OpenStreetMap started in 2004 and the rate of contributions is accelerating with four times as many people contributing to the project in 2008 compared to 2007. During the year, edits were made by some 20,000 individuals and there were bulk imports of data for many places, including the USA, India, Italy and Belarus which are clearly visible in the animation.
