# 73. クエリ: 選択したバッファを使ってグリッドデータを取得

選択したバッファを使用して「FieldSatelliteImage」「TopographyMap」「SoilDataset」「YieldDataset」「AsAppliedDataset」「VectorAnalysisMap」といったデータセットからグリッド化されたデータを取得するクエリ。

{% hint style="danger" %}
推奨：次を使用して単一のデータセットのみを取得すること `sourceDataUrl` リクエストごとに。 
{% endhint %}

`NoBuffer`, `PlusOnePixel`, `PlusTwoPixels`, `MinusOnePixel`、および `MinusTwoPixels` として利用可能です `バッファ`.

{% hint style="danger" %}
`sourceDataUrl` リンクは以下の期間のみアクセス可能です **60 秒。**
{% endhint %}

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

```graphql
query GetRawVectorDataFromSatelliteImage {
  getFarms (farmUuids: ["<placeholder_of_farm_uuid>"]){
    uuid
    名前
    fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
      uuid
      名前
      satelliteImages(satelliteImageUuids: ["<placeholder_of_satelliteimage_uuid>"]) {
        sourceDataUrl(format: GEOJSON buffer: PlusTwoPixels)
      }
    }
  }
}
```
