# Compound symbols

The symbols defined in the Fill symbols section may be combined to form aggregated symbols. To do this, the coordinates of the original symbols are translated by a specified offset. Compound symbols may be used as components to make up other compound symbols.

For example, to define the scrub fill symbol, we combine the *bushFillSymbol* and *smallBushFillSymbol* using the following translations:

#### Compound *scrubFillSymbol* example.

| <p>bushFillSymbol: translate(-0.8 1)</p><p>smallBushFillSymbol: translate(1.2 –1.2)</p><p> </p><p>The combined result, scrubFillSymbol, is drawn as:</p> | <img src="/files/aW4gFSalOtKo8DQN1krz" alt="Example visual representation of a scrubFillSymbol" data-size="original"> |
| -------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------- |

To define the mixed vegetation type of scrub and rough grass, the *scrubFillSymbol* created in the previous example is used in conjunction with *roughGrassFillSymbol*:

# Agent Instructions: 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:

```
GET https://docs.os.uk/os-downloads/products/maps-and-imagery-portfolio/os-mastermap-topography-layer/os-mastermap-topography-layer-standard-styling-specification/compound-symbols.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
