# 80. Kysely: Hae alkuperäiset tiedot

Kysely ladatun alkuperäisen datan kopion hakemiseksi: "SoilDataset", "YieldDataset", "AsAppliedDataset".

{% hint style="danger" %}
Suositellaan hakemaan vain yksi aineisto kerrallaan  `originDataUrl` pyyntöä kohti. 
{% endhint %}

`GEOTIFF` ja `GEOJSON` saatavilla muodossa `formaatit`. Mutta **vain** `GEOJSON` on nyt tuettu.

{% hint style="danger" %}
`originDataUrl` linkki on käytettävissä vain **60 sek.**
{% endhint %}

### 1. Esimerkki SoilDatasetille

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

```graphql
query GetOriginalDataOfSoilDataset {
  getFarms (farmUuids: ["<placeholder_of_farm_uuid>"]){
    uuid
    fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
      uuid
      soilDatasets(soilDatasetUuids: ["<placeholder_of_dataset_uuid>"]) {
        uuid
        originDataUrl(format: GEOJSON)
      }
    }
  }
}
```

{% endcode %}

### 2. Esimerkki YieldDatasetille

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

```graphql
query GetOriginalDataOfYieldDataset {
  getFarms (farmUuids: ["<placeholder_of_farm_uuid>"]){
    uuid
    fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
      uuid
      yieldDatasets(yieldDatasetUuids: ["<placeholder_of_dataset_uuid>"]) {
        uuid
        originDataUrl(format: GEOJSON)
      }
    }
  }
}
```

{% endcode %}

### 3. Esimerkki AsAppliedDatasetille

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

```graphql
query GetOriginalDataOfAsAppliedDataset {
  getFarms (farmUuids: ["<placeholder_of_farm_uuid>"]){
    uuid
    fields (fieldUuids: ["<placeholder_of_field_uuid>"]) {
      uuid
      asAppliedDatasets(asAppliedDatasetUuids: ["<placeholder_of_dataset_uuid>"]) {
        originDataUrl(format: GEOJSON)
      }
    }
  }
}
```

{% endcode %}

### 4. Lataa luotu tiedosto

Tiedoston onnistuneen valmistelun jälkeen se on ladattavissa käyttäen `curl` tai vastaavaa menetelmää.

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

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

{% endcode %}
