# Areas

The Area class represents a physical geographic area or a more abstract logical area. In both cases it is the 'asset container', in a sense that all assets within the area are contained by the Area instance. A physical geographic area is a specific area with a location and geometry (and can be pointed at on a map). A logical area can be an non-specific area, like 'a neighbourhood with houses from the period 1970-1990' without specifically stating where this neighbourhood is located.

An area can have a scope (like country, region, city, village, street, building and lots more) and have a type (like land, road, water, sea, ...). An area can be subdivided into smaller areas, like a city that is divided into neighbourhoods and neighbourhoods being divided into streets.

Areas can have the following properties:

* Location and geometry
* EnergyPotential (wind, solar PV, geothermal, aquifer, ...)
* Legal restrictions
* Social properties
* Economic properties

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 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://energytransition.gitbook.io/esdl/esdl-concepts/data-types/areas.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.
