# Perform Spatial Operations

The Edition extension offers two types of spatial operations: geoprocessing and spatial tools.

**Geoprocessing** concerns the set or a selection of the elements of the involved layers and their result is a set of new geometries added to the **Annotations** layer.

The operations performed by the **Spatial Tools** concern the elements selected beforehand and their result is one or more new geometries that are added to the **Annotations** layer.

{% hint style="info" %}
The layers attributes are not retained in the results (the Annotations layer has no attributes). 
{% endhint %}

The elements resulting from the operations can be selected and copied into other layers using the **Edition** tools and the **context** **menu**.

When you perform spatial operations on editable layers, you can hold down the **CTRL** key to retain only the result of the operation, that is, by automatically deleting the editable elements that were selected.

## 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-jmapserver-lima.k2geospatial.com/e/extensions/edition/i-wish-to.../perform-spatial-operations.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.
