# 8. Mutation: 「RasterMap」を生成

「Field」のために「RasterMap」を生成します。

{% hint style="info" %}
実行時間は異なります（4秒から5分まで）。処理する画像の枚数と圃場面積に依存し、「RasterMap」の生成が成功した後に購読（Subscription）が受け取られます。
{% endhint %}

{% hint style="danger" %}
次の利用を推奨します： **非同期（asynchronous）** アプローチでRastetMapを生成することをおすすめします。
{% endhint %}

{% code overflow="wrap" lineNumbers="true" %}

```graphql
mutation GenerateRasterMap {
  generateRasterAnalysisMap(input: {
    fieldUuid: "<placeholder_of_field_uuid>"
    satelliteImageUuids: [
      "<placeholder_of_satelliteimage_uuid_1>",  
      「<placeholder_of_satelliteimage_uuid_2>」
    ]
    index: NDVI
  }) {    
    uuid
    fieldUuid
    名前
    centroid {
      latitude
      longitude
    }
    boundingBox
    geoMaps {
      shortName
      fullName
      url
      classes
      hexColorCodes
    }
    status
