# Downloading the data

The OS Detailed Path Network product is available for the 15 National Park areas within Great Britain. The dataset is released in three formats: Geography Markup Language (GML), GeoPackage and vector tiles. All formats are compressed into a regular zip file (.ZIP).

Before loading the data, you will need to unzip it by using any of the regular zip programs available or via the facility within the Windows 10 operating system.

As the areas covered by the National Parks differ in size, the downloads in turn vary in size, from 11MB for the Lake District National Park to around 2MB for the Northumberland National Park.

The data is available as download only, and there are no plans for the data to be made available on hard media.

{% hint style="info" %}
**This getting started guide focusses solely on using the product in GML format.**

* For information on how to open, use and understand a **GeoPackage** dataset, please refer to our [‘Getting Started with GeoPackage’ guide](https://docs.os.uk/os-downloads/getting-started/getting-started-with-geopackage). Further detailed information on GeoPackage can be taken from the [GeoPackage website](https://www.geopackage.org/).
* For information on how to install **vector tiles (MBTiles)** and the format's key features and benefits, please refer to our [‘Getting Started with Vector Tiles’ guide](https://docs.os.uk/os-downloads/getting-started/getting-started-with-vector-tiles).

## Downloading the schema (GML format only) <a href="#bookmark4" id="bookmark4"></a>

To use the GML data format, some Geographic Information Systems (GIS) may need third-party data translation software to make the data usable within their GI application. To help with this, we provide a downloadable [XSD schema](https://www.ordnancesurvey.co.uk/xml/schema/detailedPathNetwork/v1/detailedPathNetwork.xsd) for the OS Detailed Path Network Product on on the [XML file resources page of the Ordnance Survey website](https://www.ordnancesurvey.co.uk/xml/).

1. Go to the [OS Detailed Path Network Downloads page](/os-downloads/resources/product-resources/end-of-life-product-documentation/os-detailed-path-network/os-detailed-path-network-downloads.md)
2. Find the Product schema (XML) link on the page.
3. You can either:
   * Right-click on the link and *Save link as* to a location of your choice or
   * Click the link to open the schema online, then copy and save the content into a text editor

# 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/resources/product-resources/end-of-life-product-documentation/os-detailed-path-network/os-detailed-path-network-getting-started-guide/downloading-the-data.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.
