What are Ordinance Survey maps and what do the symbols stand for? - Teacher notes

Ordnance Survey (OS) maps are detailed representations of Great Britain's topography, with a rich history dating back to 1791. Initially created in response to the Jacobite rebellion of 1745, the mapping project gained urgency due to fears of a potential invasion by Napoleon. The Ordnance Survey, now a government-run organisation headquartered in Southampton, employs around 1,200 people who are responsible for producing both traditional paper maps and digital versions, including those available on Digimap. These maps are essential tools for outdoor enthusiasts, such as walkers and explorers, who rely on them to navigate the varied landscapes of the country.

The modern way to access these maps is through the OS Maps app, which offers a user-friendly interface for navigation. The app includes a variety of symbols, each designed to represent different features on the landscape, such as footpaths, bridleways, and various points of interest. These symbols are standardised, making it easy for users to understand and interpret the geographical information provided. For those seeking to familiarise themselves with the app's functionality and the meaning of the symbols, there are several tutorials available, including a comprehensive how-to guide on YouTube that provides an overview of the app and assists users in finding their way around.
