# 50. Interogare: Obține datele pe grilă din "HartaAnalizăVectorială"

Interogare pentru a obține date grilajate din "VectorAnalysisMap" ca `GEOJSON`  cu puncte sau `GEOTIFF`. Atributul properties conține datele originale (cum ar fi valoarea indexului) pentru fiecare punct.

#### 1. Solicitați un fișier pentru export

{% hint style="danger" %}
Se recomandă preluarea doar a unui singur set de date cu `sourceDataUrl` pe solicitare. 
{% endhint %}

`FărăBuffer`, `PlusUnPixel`, `PlusDouăPixeli`, `MinusUnPixel`, și `MinusDouăPixeli` sunt disponibile ca `buffer`.

`GEOJSON` și `GEOTIFF` sunt disponibile ca format. 

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

```graphql
query GetGriddedDataFromVectorAnalysisMap {
  getFarms(farmUuids: ["<placeholder_of_farm_uuid>"]) {
    uuid
    farmOwnership
    fields(fieldUuids: ["<placeholder_of_field_uuid>"]){
      uuid
      vectorAnalysisMaps(vectorAnalysisMapUuids: ["<placeholder_of_zonesmap_uuid>"]) {
        uuid
        sourceDataUrl(format: GEOJSON buffer: PlusTwoPixels)
      }
    }
  }
}
```

{% endcode %}

#### 2. Descărcați fișierul generat

După pregătirea cu succes a fișierului, este posibil să îl descărcați folosind `curl` sau o abordare similară.

{% hint style="danger" %}
`sourceDataUrl` linkul este accesibil doar pentru **60 sec.**
{% endhint %}

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

```bash
curl '<sourceDataUrl>' --compressed >> '<local_filepath>'
```

{% 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/50.-interogare-obtine-datele-pe-grila-din-hartaanalizavectoriala.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.
