# Style definition

It is the flexibility to select and style the different feature classes in different ways that makes the vector format of OS VectorMap District such a versatile contextual mapping product. It can be flexibly styled in a wide variety of ways to best provide a geographic context to the customer’s overlay information.

The raster version is ready-styled as backdrop and full colour and these styles are fixed within the limitations of the image viewing software. Below is an example of both the raster styles. The full graphic legends are available as PDF downloads from the [OS VectorMap District product page of the OS website](https://www.ordnancesurvey.co.uk/products/os-vectormap-district).

# Agent Instructions
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://docs.os.uk/os-downloads/products/maps-and-imagery-portfolio/os-vectormap-district/os-vectormap-district-overview/style-definition.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.
