# 75. Mutación: generar "EquationMap" de forma asíncrona

## Descripción general

Generar "EquationMap" para el "Field" de forma asíncrona.

{% hint style="info" %}
El enfoque asíncrono coloca una tarea (Generar "`generateEquationMap`") para procesar y la Suscripción se recibirá tan pronto como el procesamiento haya finalizado.
{% endhint %}

## Capas de datos compatibles

Los EquationMaps pueden ejecutarse en cualquier capa de datos disponible en GeoPard, incluidas Imágenes Satelitales, Conjuntos de Datos de Suelo, Conjuntos de Datos de Rendimiento, Conjuntos de Datos Aplicados, Topografía, Mapas de Zonas e incluso otros EquationMaps. El formato de `dataVariables` la entrada variará dependiendo de la capa de datos seleccionada.

```graphql
dataVariables: [
  # ConjuntoDeDatosDeRendimiento
  {
    variable: "yield_variable"
    yieldDatasetUuid: "<placeholder_of_yielddataset_uuid>"
    yieldAttribute: "<placeholder_of_yielddataset_attribute>"
  }, 
  
  # ConjuntoDeDatosDeSuelo
  {
    variable: "soil_variable"
    soilDatasetUuid: "<placeholder_of_soildataset_uuid>"
    soilAttribute: "<placeholder_of_soildataset_attribute>"
  },
  
  # ConjuntoDeDatosAplicados
  {
    variable: "asapplied_variable"
    asAppliedDatasetUuid: "<placeholder_of_asapplieddataset_uuid>"
    asAppliedAttribute: "<placeholder_of_asapplieddataset_attribute>"
  },
  
  # ImagenSatelital
  {
    variable: "satelliteimage_variable"
    satelliteImageUuids: ["<placeholder_of_satelliteimage_uuid>"]
    index: "<placeholder_of_satelliteimage_vegetation_index>"
  },
  
  # MapaTopográfico
  {
    variable: "topography_variable"
    topographyMapUuid: "<placeholder_of_topographymap_uuid>"
    topographyAttribute: "<placeholder_of_topography_attribute>"
  },
  
  # EquationMap
  {
    variable: "equationmap_variable"
    equationMapUuid: "<placeholder_of_equationmap_uuid>"
  },
  
  # MapaDeZonas (VectorAnalysisMap)
  {
    variable: "zonesmap_variable"
    vectorAnalysisMapUuid: "<placeholder_of_zonesmap_uuid>"
  }
]
```
