# 81. Consulta: Obtener GeoJSON de "EquationMap"

Obtener GeoJSON de "EquationMaps" filtrado por `equationMapUuids`.

El atributo `equationMapGeojson` contiene GeoJSON con el `Polígonos` o `MultyPolygons` incluyendo los atributos de la característica geoespacial como `id`, `value` y `área` en las unidades definidas.

Detalles clave:

* Parámetro `asMultiGeometry: true` significa que el `Polígonos` (celdas del "Equation Map") se fusionarán en `MultiPolígonos` basado en el `value` atributo de cada celda del "Equation Map".
* El área de salida puede configurarse usando el `unidad` parámetro. Opciones disponibles: `ACRES`,  `HECTARES`, `SQUARE_METERS`

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

```graphql
query GetEquationMapGeometries {
  getFields (filter: {fieldUuid: "<placeholder_of_farm_uuid>"}) {
    fields {
      equationMaps(equationMapUuids: ["<placeholder_of_equationmap_uuid>"]) {
        equationMapGeojson(unit: HECTARES, asMultiGeometry: true)        
      }
    }
  }
}
```

{% endcode %}

Si no se solicitan geometrías (solo se requieren atributos), entonces existe `attributesJson` en lugar de `equationMapGeojson` para usar.

```graphql
query GetEquationMapAttributes {
  getFields (filter: {fieldUuid: "<placeholder_of_farm_uuid>"}) {
    fields {
      equationMaps(equationMapUuids: ["<placeholder_of_equationmap_uuid>"]) {
        attributesJson(unit: HECTARES, asMultiGeometry: true)        
      }
    }
  }
}
```

{% endcode %}
