The EUDR 25 MB geolocation limit: reduce or split your file

"The total size of geolocation data per DDS cannot exceed a certain amount (presently set to 25Mb)" (Information System validation rules, Geolocation data size). The specification adds that the limit includes the total size of the GeoJSON files uploaded to the statement (GeoJSON File Description, Common errors 16). So three 10 MB files for one statement are over it.

There is a second limit that often bites at the same time: at most 1,000 producers per commodity and 10,000 per statement (Information System validation rules, Geolocation Producers information).

What makes a file big

• Too many points. A GPS app recording every second can put thousands of vertices on one boundary.
• Too many decimals. Coordinates are cut to six decimals on arrival; the tenth decimal is paid for in bytes and thrown away.
• Altitude and extra properties. A third number on every position, and properties the system ignores, add up over tens of thousands of plots.
• Pretty-printing. Indentation can double the size of a file.

Reducing without changing what you declare

The Commission's own suggestions are fewer points along straight lines, and single points instead of polygons for plots under four hectares (GeoJSON File Description, Common errors 16). Both keep the land declared the same.

The checker's Get the file under 25 MB tries in that spirit: it removes points that do not change a boundary by more than 10 m, keeps every polygon valid, and refuses to touch any plot whose area would change by more than 2%. Every plot it simplified is listed with its area before and after, before you download.

Splitting, and grouping the statements

When reduction is not enough, split the file by producer, so no producer's plots end up in two statements. Submit each part as its own statement. Implementing Regulation (EU) 2026/1565 then lets you group statements you have already submitted by submitting a new one that references them; the grouped statement stands for the individual ones, and its reference number is the one you pass on (Implementing Regulation (EU) 2026/1565, Art. 8a).
