# 10. Mutation: genera "RasterMap" in modo asincrono

Genera "RasterMap" per il "Field" **in modo asincrono**.

{% hint style="info" %}
L'approccio asincrono mette in coda un'attività (Generate `generaMappaAnalisiRaster`) per l'elaborazione e la Subscription verrà ricevuta non appena l'elaborazione sarà terminata.
{% endhint %}

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

```graphql
mutazione GeneraRasterMapAsync {
  generaMappaAnalisiRasterAsync(input: {
    fieldUuid: "<placeholder_of_field_uuid>"
    satelliteImageUuids: [
      "<placeholder_of_satelliteimage_uuid_1>",
      "<segnaposto_uuid_immaginesatellitare_2>"
    ]
    index: NDVI
  }) {    
    uuid 
    fieldUuid
    statusCode  
  }
}
```
