# Supply and formats
The data is supplied as a free download from the [OS Data Hub](https://osdatahub.os.uk/downloads/open/MiniScale) and is updated and released annually in January. It is supplied as the whole of Great Britain, with Orkney and the Shetland Islands shown in their correct positions. Some European coastline is supplied to give context.
MiniScale is supplied in the following formats (file sizes are approximate):
* Adobe Illustrator CC 2019 or higher; file size 30 Mb
* Editable Encapsulated PostScript (EPS); file size 95 Mb
* TIFF LZW compression; file size 15–40 Mb
The Illustrator file contains the layers and styles required to customise the product. This file also contains additional layers, such as sea depths, height colouring and other information that does not appear on the default style for MiniScale. Some of the ways that MiniScale can be customised are shown in the raster examples provided.
The Illustrator file requires the font ‘Source Sans Pro’, which is supplied in the download. This is a free open source font created by Adobe. It is available from Adobe and Font Squirrel: [https://www.fontsquirrel.com/fonts/source-sans-pro.](https://www.fontsquirrel.com/fonts/source-sans-pro)
MiniScale monochrome example.
MiniScale with shaded relief (TIFF images available from supplementary file supplied).
## Managing MiniScale files
MiniScale has been created as a vector data graphic map that is favourable for use within desktop graphic applications. MiniScale’s use within GIS will be limited to backdrop mapping when using the TIFF only.
MiniScale is supplied as a single download with a variety of industry-standard formats. The Illustrator vector data is held in layers, with styled objects for easy customisation of map images. These can be easily converted to web images using appropriate software (not supplied).

## 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/miniscale/miniscale-overview/supply-and-formats.md?ask=&goal=
```
`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.
