Three approaches are available – choose the one that best fits your situation. | Approach A Point Geometry | Approach B Buffer / Expand Polygon | **Approach C** Contact osapiens Support | | --- | --- | --- | | **Best for:** Any user – recommended first step | **Best for:** Teams that need polygon geometry | **Best for:** Users without technical setup | | **Requires:** Land plot coordinates (lat/lon) | **Requires:** QGIS or AI tool + GeoJSON file | **Requires:** Access to osapiens Support Portal | | **Result:** Single GPS point | **Result:** Minimally enlarged polygon | **Result:** Processed GeoJSON file returned via support ticket | --- ## Approach A – Convert to Point Geometry *Replace the polygon with a single GPS coordinate point.* Under the EUDR regulation, plots smaller than 4 ha may be represented by a single GPS coordinate (latitude/longitude) instead of a full polygon. ### Step 1 – Identify the plot center coordinates You need the **latitude and longitude of the plot center**. How you obtain these depends on what data you already have: #### **Option 1: Use geojson.io to extract the centroid from GeoJSON:** - Open [https://geojson.io](https://geojson.io) in your browser. - Upload your GeoJSON file: use *Open → File* from the top menu, or drag and drop your `.geojson` file directly onto the map. - Your plot polygon appears on the map. Click on the polygon to select it. - A toolbar appears at the top of the page – click on the **Create Centroid** button. A new point feature is automatically placed at the polygon's centroid. - Click on the newly created centroid point. In the Feature Editor at the bottom of the page, click on **GeoJSON** to display the coordinates of the point. ![](https://cdn.document360.io/182fa27c-97b2-4266-83c9-983310ca8da9/Images/Documentation/GeoJson.io_Screenshot1.png?sv=2026-02-06&spr=https&st=2026-11-05T05%3A51%3A17Z&se=2026-11-05T06%3A51%3A17Z&sr=c&sp=r&sig=bNnwSExLqNMyi5h5%2BpsutuzFhvOjtxSYh8ZaUiS3EIw%3D) - Use the **Copy** button to copy the coordinates. You can now use the copied coordinates or the full GeoJSON file for Step 2. ![](https://cdn.document360.io/182fa27c-97b2-4266-83c9-983310ca8da9/Images/Documentation/GeoJson.io_Screenshot2.png?sv=2026-02-06&spr=https&st=2026-11-05T05%3A51%3A17Z&se=2026-11-05T06%3A51%3A17Z&sr=c&sp=r&sig=bNnwSExLqNMyi5h5%2BpsutuzFhvOjtxSYh8ZaUiS3EIw%3D) --- #### **Option 2 – Use an AI tool to extract the centroid from your GeoJSON:** - Upload your GeoJSON file to an AI tool (e.g., claude.ai) and send the following request: ```plaintext I have a GeoJSON file containing a land plot polygon. Please calculate the centroid (geographic center point) of this polygon and return the result as latitude and longitude in decimal degrees (WGS 84). ``` - The AI tool will return a single coordinate pair that you can use in Step 2. --- ### Step 2 – Create a point GeoJSON file - Create a new `.geojson` file using the following template. Replace the coordinate values with your actual plot center coordinates **from Step 1**: ```json {  "type": "FeatureCollection",  "features": [    {      "type": "Feature",      "geometry": {        "type": "Point",        "coordinates": [, ]      },      "properties": {        "name": "Plot identifier"      }    }  ] } ``` **Note:** GeoJSON uses `[longitude, latitude]` order – not `[latitude, longitude]`. --- ### Step 3 – Verify the point location - Open geojson.io in your browser and paste or upload your new file to visually confirm the point falls within the correct plot area: - [https://geojson.io](https://geojson.io) --- ### Step 4 – Upload to the osapiens Supplier Portal - Upload the new point GeoJSON file via the standard upload process in the **osapiens Supplier Portal**. --- ## Approach B – Buffer / Expand Polygon to Minimum Size *Enlarge the polygon to meet the 0.01 ha minimum threshold.* If you need to retain a polygon representation, the plot can be slightly enlarged (buffered) so that it meets the 0.01 ha minimum. The geographic centre remains unchanged. **The following options are available:** 1. Option 1 – Buffer in QGIS 2. Option 2 – Buffer via AI Tool --- ### Option 1 – Buffer in QGIS #### Step 1 – Install QGIS (if not already installed) - Download the Long Term Release (LTR) version from: - [https://qgis.org/download/](https://qgis.org/download/) - Available for Windows, macOS, and Linux. No license required. --- #### Step 2 – Load your GeoJSON file - Open QGIS and go to *Layer → Add Layer → Add Vector Layer*. Select your `.geojson` file and click on **Add**. - Tip: Drag and drop the GeoJSON file directly onto the QGIS window. --- #### Step 3 – Reproject to a metric CRS - The buffer must be applied in meters, not degrees. Right-click on the layer → *Export → Save Features As*. Set the CRS to a local metric projection (e.g. **EPSG:32632** for Central Europe / UTM Zone 32N). Click on the **Select CRS** button to browse all available coordinate systems. Save as a temporary file. ![](https://cdn.document360.io/182fa27c-97b2-4266-83c9-983310ca8da9/Images/Documentation/01.png?sv=2026-02-06&spr=https&st=2026-11-05T05%3A51%3A17Z&se=2026-11-05T06%3A51%3A17Z&sr=c&sp=r&sig=bNnwSExLqNMyi5h5%2BpsutuzFhvOjtxSYh8ZaUiS3EIw%3D) --- #### Step 4 – Apply buffer - Go to *Vector → Geoprocessing Tools → Buffer*. Set the Distance to a value that will bring the area above 0.01 ha. As a guideline, a circular buffer of 6 meters around a point yields approx. 0.011 ha. - Run the tool. The result is a new buffered polygon layer. ![](https://cdn.document360.io/182fa27c-97b2-4266-83c9-983310ca8da9/Images/Documentation/02.png?sv=2026-02-06&spr=https&st=2026-11-05T05%3A51%3A17Z&se=2026-11-05T06%3A51%3A17Z&sr=c&sp=r&sig=bNnwSExLqNMyi5h5%2BpsutuzFhvOjtxSYh8ZaUiS3EIw%3D) --- #### Step 5 – Verify area - Open the Attribute Table of the buffered layer. Use the Field Calculator to confirm the area: **Expression:** `$area / 10000`. Confirm that the value is ≥ 0.01 ha. - Choose an output field name to be able to click on **OK**. ![](https://cdn.document360.io/182fa27c-97b2-4266-83c9-983310ca8da9/Images/Documentation/03.png?sv=2026-02-06&spr=https&st=2026-11-05T05%3A51%3A17Z&se=2026-11-05T06%3A51%3A17Z&sr=c&sp=r&sig=bNnwSExLqNMyi5h5%2BpsutuzFhvOjtxSYh8ZaUiS3EIw%3D) --- #### Step 6 – Export as GeoJSON (WGS 84) - Right-click the buffered layer → *Export → Save Features As*. Choose Format: **GeoJSON** and set the CRS to **EPSG:4326 (WGS 84)**. Save the file. --- #### Step 7 – Upload to the osapiens Supplier Portal - Upload the exported GeoJSON file via the standard upload process in the **osapiens Supplier Portal**. --- ### Option 2 — Buffer via AI Tool #### Step 1 – Open an AI tool in your browser - Go to the AI tool and sign in. (E.g., use the standard Claude chat interface at claude.ai – no special setup required.) --- #### Step 2 – Upload your GeoJSON file - Click on the plus button and then on the paperclip/attachment icon in the chat input and attach your `.geojson` file. --- #### Step 3 – Send your request - Use a prompt like the following: ```plaintext I have a GeoJSON file containing a land plot polygon that is smaller than 0.01 ha (100 m²). The osapiens Supplier Portal requires a minimum plot size of 0.01 ha to upload. Please do the following: 1. Calculate the centroid of the polygon. 2. Compute the radius required for a circle with an area of exactly 0.01 ha (100 m²), converting meters to decimal degrees at the correct latitude. 3. Generate a circular polygon (36 vertices) centered on the centroid with that radius. 4. Return the result as a valid GeoJSON FeatureCollection with CRS EPSG:4326. ``` - The AI tool can perform these calculations directly and will return a ready-to-upload GeoJSON polygon. --- #### Step 4 – Verify the output - Open [https://geojson.io](https://geojson.io) and upload the returned file. Confirm that: - The polygon is centered on the original plot location. - The shape appears as a small circle (this is expected – the polygon is a circular approximation). - No obvious errors or misplaced coordinates are visible. --- #### Step 5 – Upload to the osapiens Supplier Portal - Upload the verified GeoJSON file via the standard upload process in the **osapiens Supplier Portal**. --- ## Approach C – Contact the osapiens Support Team ### Step 1 – Open the osapiens Support portal - Access the osapiens support portal via the link available in the Supplier Portal: [https://supplier-support.osapiens.com/support/home](https://supplier-support.osapiens.com/support/home) --- ### Step 2 – Create a new support ticket - Click on **Submit a new ticket** and fill out the relevant fields: - E-mail address - Subject: "Request to buffer plot smaller than 0.01 hectare" - Application: "EUDR" - Company name - Corresponding osapiens customer for suppliers (optional) - Environment: Demo vs. Production --- ### Step 3 – Describe your request - In the ticket description, include: - The number of plots affected - Whether you prefer a buffer (polygon) or point geometry as the output - Any additional context relevant to the plots --- ### Step 4 – Attach the GeoJSON file - Use the file attachment option in the ticket form to upload your `.geojson` file. --- ### Step 5 – Receive and upload the processed file - The support team will process your request and return the updated GeoJSON file via the ticket. - Once received, upload it via the standard upload process in the **osapiens Supplier Portal**.
