# Pattern definitions

## Creating a pattern <a href="#id-3.6.1-creating-a-pattern" id="id-3.6.1-creating-a-pattern"></a>

The symbols defined in Symbols and Compound symbols that end with the term *FillSymbol* are all used for pattern fills. The name of the pattern is taken from the symbol name by replacing *FillSymbol* with the term *Pattern*.

The exceptions to this principle are:

* *scatteredBouldersPattern* uses *smallBoulderFillSymbol*
* *scatteredRocksPattern* uses *smallRockFillSymbol*
* *scatteredConiferousTreesPattern* uses *smallConiferousTreeFillSymbol*
* *scatteredNonconiferousTreesPattern* uses *smallNonconiferousTreeFillSymbol*

To produce a particular pattern, the appropriate fill symbol is distributed on a grid that is repeated to cover the polygon being drawn. The sections below detail the grids that are currently in use.

### Example grid pattern <a href="#id-3.6.6-example-grid-pattern" id="id-3.6.6-example-grid-pattern"></a>

In this example, *heathAndScrubPattern* uses the natural environment grid to produce the pattern below:

<figure><img src="/files/DTNAJybWTux1QxkCPGWe" alt="Example visual representation of heathAndScrubPattern using the natural environment grid." width="211"><figcaption><p>Example <em>heathAndScrubPattern</em> using the natural environment grid.</p></figcaption></figure>

This is then applied as a polygon fill:

# 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/pattern-definitions.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.
