The OSM Inspector (alias OSMI) is a web based debugging tool for advanced OpenStreetMap users offered by Geofabrik. On a map you can see several themed views, each with several layers, showing specific details of the OSM data, often with highlighted errors. Layers can be switched on and off, details about any feature is available on mouse click and links lead to your favourite editor so that you can fix problems easily.


Currently the following views are available, click in the Name-link to see specific OSMI documentation:

Applicable area Name Description
World Geometry Shows basic geometry problems such as overlong ways
World Routing Shows probable errors related to routing and navigation
World Tagging Shows basic problems with tag keys and values
World Places Shows places such as cities and towns
World Highways Shows problems with highway tags
World Areas Shows problems with areas (closed ways, multipolygon relations and boundary relations), e.g. missing or inappropriate role, unclosed ways as multipolygon members, self-intersecting areas
World Coastline Shows problems in coastlines

What is Open about OSM Inspector and what isn't

The data sets which OSM Inspector is based on have been generated as a side product by custom, Geofabrik-internal data processing in the past. With the release of the new Public Transport views in October 2017, the whole processing of all views is solely based on open source tools (only some scripts running as cronjobs are closed source).

The results, however, can not only be viewed in OSM Inspector, but they can also be downloaded in raw form through WMS and WFS interfaces. (See OSM Inspector/WxS for details.) On request, most layers can also be made available as shape files (you can use WFS download to produce a shape file but that is painfully slow for large areas.)
