EUDR GeoJSON rejected: open polygon

Why the EU Information System (TRACES) rejects an open polygon in an EUDR plot file, how to close it by hand, and a free tool that closes every ring automatically.

What the EU Information System expects

Each polygon ring must be closed: its last coordinate pair must be identical to its first. The open polygon is one of the common errors the documentation lists as blocking a GeoJSON upload.

Source: EU Information System, “GeoJSON File Description” (European Commission), read on 27 October 2026.

Fix it by hand

In the GeoJSON, copy the first coordinate pair of each ring and add it again at the end of that ring. Drawing apps that export a line instead of a polygon are the usual cause.

Fix it automatically

The checker closes every open ring and lists each plot it fixed; the corrected GeoJSON is ready to download.
