# 14. Mutaatio: luo "Field" tai muokkaa olemassa olevan lohkon rajaa (valinnaisilla tunnisteilla)

Luo "Pelto" tai muokkaa olemassa olevan pellon rajaa.

{% hint style="danger" %}
"Pelto" `geojson` attribuutin on oltava WGS84 (EPSG:4326) -projektion mukainen, alle 1040ac / 420ha, ja noudatettava [määrittelyä](https://geojson.org/).

Tuetut `geojson` tyypit ovat `MultiPolygon` ja `Polygon`.
{% endhint %}

Käyttötiedot:

* Attribuutti `tunnisteet` on kartta, jossa avain (tunnisteen nimi) ja arvo (tunnisteen arvo) -pareja.
* Oman "Tilan" (Farm) yksilöllisen tunnisteen linkitys attribuutin kautta on mahdollista. Attribuutti on valinnainen.
* Attribuutit `status` ja `statusMessage` korostaa rekisteröinnin tulosta. " `"status"=INVALID` vastaus tarkoittaa, että "Pellon" pyyntöä on tutkittava. Lisätietoja tuloksista löytyy `statusMessage`.

Muokkaa **Muokkaa** olemassa olevaa "Peltoa", lisää `uuid` attribuutti pyyntöön. Ero on attribuutissa, `uuid` attribuutti joka määrittää "Pellon" rajan muuttamista varten.
