# 14. Mutatie: een "Field" aanmaken of de grens van het bestaande veld bewerken (met optionele labels)

Maak een "Perceel" aan of bewerk de grens van het bestaande perceel.

{% hint style="danger" %}
"Perceel" `geojson` attribuut moet in WGS84 (EPSG:4326) projectie zijn, minder dan 1040ac / 420ha, en voldoen aan de [specificatie](https://geojson.org/).

Ondersteunde `geojson` typen zijn `MultiPolygon` en `Polygon`.
{% endhint %}

Gebruikdetails:

* Attribuut `labels` is een kaart met sleutel (labelnaam) en waarde (labelwaarde) paren.
* Het koppelen van uw eigen unieke "Boerderij" identificatie via het \
   attribuut is mogelijk. Het attribuut is optioneel.
* Attributen `status` en `statusMessage` markeer het resultaat van de registratie. De `"status"=ONGELDIG` reactie betekent dat verder onderzoek van het "Perceel" verzoek vereist is. Meer details over de resultaten staan in `statusMessage`.

Om te **Bewerken** het bestaande "Perceel", voeg het `uuid` attribuut toe aan het verzoek. Het verschil zit in het `uuid` attribuut dat het "Perceel" definieert om de grens aan te passen.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.geopard.tech/geopard-tutorials/nl/api-docs/overzicht-van-api-verzoeken-van-geopard/14.-mutatie-een-field-aanmaken-of-de-grens-van-het-bestaande-veld-bewerken-met-optionele-labels.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
