# 73. Vaicājums: iegūt režģotos datus ar atlasīto buferi

Vaicājums, lai iegūtu režģa datus no datu kopām, piemēram, "FieldSatelliteImage", "TopographyMap", "SoilDataset", "YieldDataset", "AsAppliedDataset", "VectorAnalysisMap" ar izvēlēto buferi.

{% hint style="danger" %}
Ieteicams izgūt tikai vienu datu kopu ar `sourceDataUrl` vienā pieprasījumā. 
{% endhint %}

`NoBuffer`, `PlusOnePixel`, `PlusTwoPixels`, `MinusOnePixel`, un `MinusTwoPixels` ir pieejami kā `buferis`.

{% hint style="danger" %}
`sourceDataUrl` saite ir pieejama tikai **60 sek.**
{% endhint %}

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

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

{% endcode %}
