Ordnance Survey Maps

The British Ordnance Survey Team, a government mapping agency, is responsible for updating maps using modern technology. Originally established in response to the French Revolution, the agency's early maps were created through manual land measurement and triangulation. Today, the team employs aerial surveys and electronic mapping to record changes in the landscape, ensuring maps are current. These updates are crucial for services like emergency response and navigation, highlighting the Ordnance Survey's vital role in British life.
