# OS Download Products' Documentation

Explore documentation and guides for OS Premium and OpenData Download products, such as AddressBase Premium, OS MasterMap Topography Layer, Boundary-Line and OS Open Zoomstack.

## What's available on this site?

This is a self-serve site containing documentation and guides relating to Ordnance Survey (OS) Premium and OpenData Download products [available to download through the OS Data Hub](https://osdatahub.os.uk/). 

The Download products are grouped by portfolio: Addressing and Location, Contextual or Derived, Networks, Topography, Identifiers, and Height. 

On the left-hand-side menu, under each product listing, we've arranged the documents from high-level Overview to low-level Technical Specification. A Getting Started Guide and Release Notes are available for most products. We've also added links to any additional files (for example, CSV header files, stylesheets and XML schemas) available for some products but held on separate OS sites on product-specific 'Downloads' pages.

There's a [Product Announcements page](/os-downloads/~/changes/AJZwzCsyrD9hiTbOxIbO/resources/product-announcements.md) for notable product news, a [Product Refresh Dates page](/os-downloads/~/changes/AJZwzCsyrD9hiTbOxIbO/resources/product-refresh-dates.md) that details product update schedules, and a [PSGA Product Summary page](/os-downloads/~/changes/AJZwzCsyrD9hiTbOxIbO/resources/psga-product-summary.md), which lists all of the OS data products available to Public Sector Geospatial Agreement (PSGA) Members on an unlimited basis across the downloadable products, APIs and OS National Geographic Database (OS NGD).

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.os.uk/os-downloads/~/changes/AJZwzCsyrD9hiTbOxIbO/os-download-products-documentation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
