# 81. Query: Get GeoJSON of "EquationMap"

Get GeoJSON of "EquationMaps" filtered by `equationMapUuids`.

The attribute `equationMapGeojson` contains GeoJSON with the `Polygons` or `MultyPolygons` including the geospatial feature attributes like `id`, `value` and `area` in the defined units.

Key details:

* Parameter `asMultiGeometry: true` means that the `Polygons` ("Equation Map" cells) will be merged into `MultiPolygons` based on the `value` attribute of every "Equation Map" cell.
* The output area can be configured using the `unit` parameter. Available options: `ACRES`,  `HECTARES`, `SQUARE_METERS`

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

{% endcode %}

If geometries are not requested (only attributes are required), then there is `attributesJson` instead of `equationMapGeojson` to use.

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