# 73. Sorgu: Seçili tampon ile Izgaralı Veriyi getir

Seçilen tampon ile "FieldSatelliteImage", "TopographyMap", "SoilDataset", "YieldDataset", "AsAppliedDataset", "VectorAnalysisMap" gibi veri setlerinden ızgara şeklinde (gridded) veri almak için sorgu.

{% hint style="danger" %}
Sadece tek bir veri kümesi almak önerilir `sourceDataUrl` istek başına. 
{% endhint %}

`NoBuffer`, `PlusOnePixel`, `PlusTwoPixels`, `MinusOnePixel`, ve `MinusTwoPixels` olarak kullanılabilir `tampon`.

{% hint style="danger" %}
`sourceDataUrl` link yalnızca erişilebilir **60 sn.**
{% endhint %}

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

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

{% endcode %}
