Build a compliant EUDR geolocation payload: points versus polygons, GeoJSON structure, coordinate precision, CRS and file size limits

Documented steps

1. For every plot of land supplying the commodity, record latitude and longitude with at least six decimal digits, the minimum set by Article 9 of Regulation (EU) 2023/1115.
2. Check plot area: for non-cattle commodities a single point is acceptable only for plots of 4 hectares or less; plots above 4 hectares must be delineated as a polygon with enough vertices to describe the perimeter. Cattle plots may use points regardless of size.
3. Reproject all coordinates to WGS 84 / EPSG:4326 decimal degrees. The system does not reproject other coordinate reference systems for you.
4. Build a GeoJSON FeatureCollection using only Point, MultiPoint, Polygon or MultiPolygon geometries. Polygons must be closed rings without holes and without self-intersections.
5. Add the recommended per-feature properties: ProducerName, ProducerCountry (ISO2), ProductionPlace and Area in hectares as a number.
6. Set Area explicitly on point features; leaving it out causes the system to assume 4 hectares, which can misstate a larger plot.
7. Keep the combined GeoJSON payload for a single submission under the 25 MB limit; split larger supply bases across multiple files or statements.
8. Cross-check each plot's country against the current country benchmarking classification before finalising the linked risk assessment.
9. Upload the GeoJSON in the geolocation step of the EUDR Information System, or draw plots on the map, or key in individual coordinates.
10. Validate the file in the ACCEPTANCE environment before submitting in PRODUCTION; malformed geometry is a leading rejection cause.
