Global Map of OSM Activity

OSM Activity is a global heat map of OpenStreetMap edits made around the world. The map shows the number of changes made to OpenStreetMap in each map tile area dating back to 2008.

If you zoom in on the map you can click on a map tile to view a graph displaying the number of changes made to OpenStreetMap in that area. The graph itself is also interactive. You can mouse-over the graph to view the number of changes made in the selected area for any month dating back to 2008.

You can discover more about the map and how it was made on the OSM Activity GitHub. You can also download the OSM activity data in GeoJSON format from the GitHub page.
