# GeoNode

## Overview

**GeoNode** provides a data structure designed for geospatial analytics, enabling users to **manage and query spatial entities** based on their geographic locations.

This structure allows you to store and search geospatial data through the use of a spatial index, helping to identify nearby entities within a specific area.

By using GeoNode, custom spatial analytics can be easily developed, **extending the base implementation to handle location-based data** efficiently.

## 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.fractalworks.io/joule/concepts/key-joule-data-types/geonode.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.
