MultiPoint plot with a large area may need polygons

What the Information System does

Type II files may use MultiPoint (GeoJSON File Description, File Variants Description, Type II), and the Area property applies to points (GeoJSON File Description, Definitions). The documentation does not say how a MultiPoint's Area is shared between its points. The regulation requires polygons for any plot over four hectares (Regulation (EU) 2023/1115, Art. 2(28)), which is why we warn.

A broken example

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {
        "ProducerCountry": "CI",
        "ProductionPlace": "Many points",
        "Area": 40
      },
      "geometry": {
        "type": "MultiPoint",
        "coordinates": [
          [-5.123456, 6.123456],
          [-5.122456, 6.123456]
        ]
      }
    }
  ]
}

What the checker reports for this file:

1. This MultiPoint declares 40 hectares across 2 points. Over four hectares the regulation expects a polygon for each plot., line 9, column 17

Fix it in EUDRplot

1. Open the file in the checker. The MultiPoint and its declared Area are shown.
2. One feature per plot. Split the MultiPoint into separate Point features, each with its own Area, so each plot's size is stated.
3. Polygons for large plots. Any of those plots over four hectares needs a polygon.

Fix it in QGIS

1. Split the points. Run Multipart to singleparts from the Processing Toolbox. Each point becomes its own feature, keeping the properties.
2. Set each Area. Update Area for each point from your source data; the original total is no longer right for any single point.
