# 81. Užklausa: gauti „EquationMap“ GeoJSON

Gaukite „EquationMaps“ GeoJSON, filtruotą pagal `equationMapUuids`.

Atributas `equationMapGeojson` sudaro GeoJSON su `Poligonai` arba `MultiPoligonais` įskaitant geovietos požymių atributus, tokius kaip `id`, `reikšmė` ir `plotas` nurodytomis vienetų reikšmėmis.

Pagrindinės detalės:

* Parametras `asMultiGeometry: true` reiškia, kad `Poligonai` („Equation Map“ langeliai) bus sujungti į `MultiPoligonai` remiantis `reikšmė` kiekvieno „Equation Map“ langelio atributu.
* Išvesties plotas gali būti sukonfigūruotas naudojant `vienetą` parametrą. Galimi pasirinkimai: `AKRAI`,  `HEKTARAI`, `KVADRATINIAI_METRAI`

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

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

{% endcode %}

Jei geometrijos nėra prašomos (reikalingi tik atributai), tuomet yra `attributesJson` vietoje `equationMapGeojson` naudoti.

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