man_made=works denotes an industrial production plant, also known as a factory. It may be associated with a single building where production takes place, or with a broader factory area containing multiple buildings.
works is as an outlier in the man_made=* group, which mostly includes simple infrastructural objects. In contrast, large production plants may cover large extents of land, containing multiple buildings and man-made structures.
How to map
Draw a node at the center of the facility, or the center of the relevant building. Alternatively, draw a polygon around the whole area of the production site and tag accordingly.
When increasing the level of detail, it is also possible to use this tag for individual production units inside a factory (e.g. where separate components are produced at a car plant) thus justifying separate tagging from the main area.
Historically, this tag has been used for buildings where industrial production activity takes place. This article was edited after a discussion on the Tagging mailing list, to shift the meaning from a production facility building, to an area that may include multiple such buildings and related infrastructure. As of November 2025[update] about 40% of all usage cases for the tag are combined with building=*.
For a single industrial building, not necessarily housing a production facility, use building=industrial.
Stuff produced
Use the key product=* to specify what is produced in the factory. Depending on the manufactured product range and information available, it may be broader (e.g. product=food) or more precise term (e.g. product=confectionery).
