API for analyzing and visualizing changes in OSM data

OWL (OpenStreetMap Watch List) is a service that monitors, processes and stores changes in OSM data. A major feature is that rather than calculate the bounding box of all changes in a changeset, OWL attaches changes to small tiles, which are more useful for visualization - it is possible to show only relevant changes, not all changes with overlapping bounding box.

Current status

  • Beta version of OWL/OSM.org website integration (new History tab powered by OWL) is running on zark (go to the location in question and click on "History (beta)").
  • Beta status: Replication: OK (up-to-date and processing current changes) History - processing in progress
  • OWL API server currently runs at http://owl.openstreetmap.org/.
