OpenStreetMap landuse=farmland (OSMF)
Community-mapped farmland polygons, globally.
What this is
OpenStreetMap's farmland-tagged polygons cover agricultural land across the globe, crowd-mapped by volunteers. Density varies — Western Europe is rich, much of Central Asia and sub-Saharan Africa is sparse. Accessible via the Overpass API, bulk data exports, or the OSM Landuse project's tiles.
Why we surface it
When no official parcel layer exists, OSM farmland fills the gap, and it's honest about where its coverage is thin.
What you can do with it
Shown for commercial use. Personal, research, and nonprofit use is often more permissive — switch the verdict lens on the catalog.
- Internal / individual use
- Free to use internally, including commercial work. Database share-alike only triggers when you share the database itself.
- Redistribute the data
- Redistributing the database (or a big chunk of it) means: credit the source, keep it open, and license it share-alike under ODbL.
- Republish a derivative
- Depends what you're publishing. A 'map, report, or image' made from the data (a 'Produced Work') only needs attribution. A 'derived database' must stay open under ODbL. Know which one you're shipping.
- Build into a private product
- A closed derived 'database' is blocked by ODbL's share-alike. (A Produced Work baked into a product is OK with attribution — if that's your case, treat it as the share-derivative answer.)
This decoder is a starting point, not legal advice. For commercial deployment, run the actual license terms past someone who reads them for a living.

Not in the map yet — this source is on the V1 backlog. Schema, sample, and citation slots fill in once the layer ships.
