Originally Ordnance Survey was started as an agency to serve a military purpose. Its main goal was to map Scotland and the national boundaries in the wake of Jacobite rising of 1745 and the potential threats emanating from Napoleonic Wars. The Government of that time also realised South Coast of England needed to be accurately mapped to defend it. So it instructed its Board of Ordnance – the Defence Ministry at that time – to do the required survey work. It was an historic decision which led to the mapping of the whole country in detail and also was the source of the intriguing name ‘Ordnance Survey’.
Now in its present form, Ordnance Survey (OS) is a national mapping organisation of the UK and is considered as one of the world's largest producers of maps. Coming to be known as Ordnance Survey Ltd since 1st April 2015, it became a government-owned company with 100% public ownership. It is accountable to the Secretary of State for Business, Energy and Industrial Strategy and is also a member of the Public Data Group. Mapping done by Ordinance Survey is crucial in times of disaster management teams, emergency services for the best routes possible and civil engineers and developers to find the ideal site to build on. But that’s not all, from civil developers to surveyors and cartographers to marketers, the mapping products developed by Ordinance survey are a lifeline to many.

Contribution to Geographical Studies and Research
Ordnance Survey has a research department which has contributed to Geographical Studies and Research for several decades now. The sphere of its research has especially been in areas like:
Ordnance Survey through a dedicated university liaison team actively carries out academic research and external research. The aim is to provide society and people a mapping that informs guides and inspires. To reveal an ever-changing landscape in extraordinary detail giving a comprehensive detailed view of Britain. On board, Ordnance Survey has MSc and PhD students who are always trying to understand how people could use geographic information more effectively. All content is designed to meet users’ needs now and in the future and their need to see every route or terrain getting mapped.
