# OS Detailed Path Network Getting Started Guide

The OS Detailed Path Network product is a topologically connected link and node network for roads, tracks, paths and rights of way within the National Parks of Great Britain. The product has been created from a number of existing Ordnance Survey data sources, including OS MasterMap Topography Layer, OS MasterMap Highways Network, 1:25 000 Scale Colour Raster, OS Terrain 5 and OS Terrain 50. The data is intended to provide sufficient detail for routing pedestrians, cyclists and horse riders when using mobile devices, with a typical positional accuracy of 10m.

The OS Detailed Path Network dataset was originally released in 2015. It is currently updated on an annual basis and coverage is restricted to the National Park areas of Great Britain.

## Adherence to standards <a href="#bookmark1" id="bookmark1"></a>

OS Detailed Path Network is a derived product that has been designed with consideration of the [INSPIRE](https://inspire.ec.europa.eu/) Transport Networks Data Specification, although INSPIRE does not apply to off road transport. Due to the process of deriving OS Detailed Path Network, feature instances and their identifiers will be regenerated at each data refresh.
