A Chrome extension for inspecting OpenStreetMap changesets and accessing mapping and quality assurance tools. Version 2.0 adds a viewer for deleted objects.
- Detect the changeset from an OSM changeset or object page, or enter its ID manually.
- Inspect mapper information, changeset comments, editor, date and bounding box, with translation links and alerts.
- Open OSMCha, Achavi, OSMViz, Osmose, OSM Inspector, Map Compare, LOSMET, TagInfo and Relation Analyzer.
- Save changesets to a local watchlist, with JSON import and export.
- View deleted ways and standalone nodes on a map, with all tags from their last available visible version before deletion. Nodes belonging to listed ways are hidden from the list.
The deleted-object viewer is read-only: it does not restore or modify OSM data. The highlighted geometry is historical; the background map shows current OSM data. Missing geometry is reported. Deleted relations are not supported yet.
Interface languages: English, Italian and Slovak.
