How OpenStreetMap developed

It is not only OpenStreetMap insiders who are interested in seeing how a city map or even a whole country's coverage developed over time. Our Geofabrik Labs server has a simple application where everyone can create their own animations.

Creating animations like that is not easy because OpenStreetMap is a fast-changing project. Historic data is available but not in the same formats that are in use at OpenStreetMap today, so old versions of software packages have to be used to process old data.
