# 81. Interogare: Obține GeoJSON-ul pentru "HartaEcuației"

Obține GeoJSON pentru "EquationMaps" filtrat după `equationMapUuids`.

Atributul `equationMapGeojson` conține GeoJSON cu `Poligoane` sau `MultiPoligoane` inclusiv atributele caracteristicii geospațiale precum `id`, `value` și `suprafață` în unitățile definite.

Detalii cheie:

* Parametru `asMultiGeometry: true` înseamnă că `Poligoane` (celulele „Equation Map”) vor fi îmbinate în `MultiPoligoane` pe baza `value` atributului fiecărei celule „Equation Map”.
* Suprafața de ieșire poate fi configurată folosind `unitatea` parametrului. Opțiuni disponibile: `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: HECTARE, asMultiGeometry: true)        
      }
    }
  }
}
```

{% endcode %}

Dacă geometrille nu sunt solicitate (doar atributele sunt necesare), atunci există `attributesJson` în loc de `equationMapGeojson` de utilizat.

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

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

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.geopard.tech/geopard-tutorials/ro/documentatie-api/prezentare-generala-a-cererilor-api-geopard/81.-interogare-obtine-geojson-ul-pentru-hartaecuatiei.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
