# 51. Vaicājums: iegūt režģotos datus no "Ražas datu kopas"

Vaicājums, lai iegūtu režģotos datus no rastra datu kopas, kas saistīta ar "YieldDataset", kā `GEOJSON`  ar punktiem vai `GEOTIFF`.Properties atribūtā ir visi datu kopas atribūti par punktu. 

#### 1. Pieprasiet failu eksportēšanai

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

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

`GEOJSON` un `GEOTIFF` ir pieejami kā formāts. 

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

```graphql
query GetGriddedDataFromYieldDataset {
  getFarms (farmUuids: ["<vietturis_priekš_farmas_uuid>"]){
    uuid
    fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
      uuid
      yieldDatasets(yieldDatasetUuids: ["<placeholder_of_dataset_uuid>"]) {
        uuid
        sourceDataUrl(format: GEOJSON buffer: PlusTwoPixels)
      }
    }
  }
}
```

{% endcode %}

#### 2. Lejupielādējiet ģenerēto failu

Pēc veiksmīgas faila sagatavošanas to var lejupielādēt, izmantojot `curl` vai līdzīgu pieeju.

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

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

```bash
curl '<sourceDataUrl>' --compressed >> '<local_filepath>'
```

{% endcode %}
