Diving into Digital Mapping History with OpenStreetMap

摘要

Atool develeped by Mapbox explores "10 years of OpenStreetMap." During that decade,hundreds of thousands of people mapped 25 million miles of roads in every country in the world. The internet tool uses a slider to show the data change over time. You can see additions and edits as they come online over the decade - a fascinating look at the intricate information that has been compiled. When a user drags the slider to the left, it's easy to see how scant the information was only a few years into OpenStreetMap's existence (the image at right shows the same European region in 2009 as the image at the top in 2015).
