# 10. Mutation: Generate "RasterMap" asynchronously

Generate "RasterMap" for the "Field" **asynchronously**.

{% hint style="info" %}
The asynchronous approach puts a task (Generate `generateRasterAnalysisMap`) to process and the Subscription will be received as soon as the processing is finished.
{% endhint %}

```graphql
mutation GenerateRasterMapAsync {
  generateRasterAnalysisMapAsync(input: {
    fieldUuid: "<placeholder_of_field_uuid>"
    satelliteImageUuids: [
      "<placeholder_of_satelliteimage_uuid_1>",
      "<placeholder_of_satelliteimage_uuid_2>"
    ]
    index: NDVI
  }) {    
    uuid 
    fieldUuid

}
