# 1:50 000 Scale Colour Raster Overview

1:50 000 Scale Colour Raster is a data product similar to the popular OS Landranger Map series, showing a detailed overview of the landscape. It is a mid-scale product that's ideal for navigation. 1:50 000 Scale Colour Raster can be used to contextualise your data or as a map in its own right. It is aimed at recreational as well as businesses users, providing them with an excellent overview of the main features and communication routes across Great Britain.

The 1:50 000 Scale Colour Raster product provides a grid of easy to consume TIFF images. This grid is aligned to the National Grid (EPSG: 27700). The 254 dots per inch resolution has been chosen as it maintains the necessary clarity for text shown on the map.

Screen images can be plotted to produce a high-quality map. An example of the data is shown in the image below:

## 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/1-50-000-scale-colour-raster/1-50-000-scale-colour-raster-overview.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.
