# 8. Mutatie: "RasterMap" genereren

Genereer "RasterMap" voor het "Field".

{% hint style="info" %}
De uitvoeringstijd varieert (van 4 seconden tot 5 minuten), dit hangt af van het aantal afbeeldingen en het te verwerken veldoppervlak, en de Subscription wordt ontvangen na de succesvolle generatie van de "RasterMap".
{% endhint %}

{% hint style="danger" %}
We raden aan het gebruik van de **asynchrone** benadering om RastetMap te genereren
{% endhint %}

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

```graphql
mutatie GenerateRasterMap {
  generateRasterAnalysisMap(input: {
    fieldUuid: "<placeholder_of_field_uuid>"
    satelliteImageUuids: [
      "<placeholder_of_satelliteimage_uuid_1>",  
      "<plaatsaanduiding_van_satellietbeeld_uuid_2>"
    ]
    index: NDVI
  }) {    
    uuid
    fieldUuid
    naam
    centroid {
      breedtegraad
      lengtegraad
    }
    boundingBox
    geoMaps {
      korteNaam
      volledigeNaam
      url
      classes
      hexColorCodes
    }
