# Adding Data

To add data to a project, select a data source, then drag and drop it onto the map.

{% hint style="info" %}
You can add the same data source multiple times: each addition creates a new spatial layer or data table in the project.
{% endhint %}

* Spatial data appears in the **Layers** section of the project.
* Data tables appear in the **Tabular Data** section.

Once data is added, you can organize and configure the layers as needed.

## Adding Data from WMS/WMTS Data Sources

Adding data from WMS/WMTS data sources has certain particularities. When you add a WMS/WMTS data source as a layer to a project, the layer is created based on the information provided by the GetCapabilities request:

* Includes the first available layer that supports EPSG:3857.
* Includes the first available style for the layer.
* Uses PNG image format. If PNG is not available, JPG/JPEG is used; otherwise, the first available format from the service is used.

If the WMS/WMTS service does not meet one of these requirements (for example, no layer supports EPSG:3857), the layer is not created and an error message notifies the user.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jmapcloud.io/en/jmap-cloud-portal/user-guide-for-jmap-cloud-portal/configuring-project-data/adding-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
