# Geoprocessing

## Intersection

You can intersect the whole or a selection of the elements of two layers:

1. Select the Intersection function from **Tools -> Geoprocessing** in the menu bar.
2. From the drop-down menus, select the layers whose elements will be intersected.
3. Press **Execute**. \
   To intersect the selected elements, check the relevant box. \
   The resulting elements of the intersection appear colored and are added to the **Annotations** layer.\
   These are new geometries resulting from the individual intersection of each of the geometries of the first layer with each of the geometries of the second layer.

4. You can then copy them to another layer displayed in the application if you have permissions to add elements to it.

## 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/geoprocessing.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.
