The Annotation Process in OpenStreetMap
Transactions in GIS, 2012AbstractIn this article we describe the analysis of 25,000 objects from the OpenStreetMap (OSM) databases of Ireland, United Kingdom, Germany, and Austria. The objects are selected as exhibiting the characteristics of “heavily edited” objects. We consider “heavily edited” objects as having 15 or more versions over the object's lifetime.

OpenStreetMap is a wiki-style map of the world. In this animation, each time a feature is entered or updated it flashes white and then decays through yellow and red to purple. Some edits are a result of a physical local survey by a contributor with a GPS unit and a notepa. Other edits are done remotely using aerial photography or out-of-copyright maps.
