# 14. Mutation: 「Field」を作成、または既存圃場の境界を編集（任意のラベル付き）

「圃場（Field）」を作成するか、既存の圃場の境界を編集します。

{% hint style="danger" %}
「圃場（Field）」 `geojson` 属性はWGS84（EPSG:4326）投影法で、1040エーカー／420ヘクタール未満で、次に従う必要があります。 [仕様](https://geojson.org/).

サポートされている `geojson` タイプは次のとおりです。 `MultiPolygon` と `Polygon`.
{% endhint %}

使用の詳細：

* 属性 `ラベル` はキー（ラベル名）と値（ラベル値）のペアを持つマップです。
* 独自の「農場（Farm）」の一意識別子を属性を介して連携することが可能です。属性は任意です。
* 属性 `status` と `statusMessage` 登録の結果を強調表示します。 `「status"=INVALID（無効）」` の応答は「圃場」リクエストの調査が必要であることを意味します。結果の詳細は次にあります。 `statusMessage`.
