Therefore, an "O.S. map" refers to a map produced by the Ordnance Survey. These maps are known for their accuracy, detail, and comprehensive coverage of the UK.
Here's what you might find on an O.S. map:
* Topographical features: Contours, rivers, lakes, forests, buildings, roads, and more.
* Grid references: A system to accurately locate any point on the map.
* Scale: The ratio between distances on the map and real-world distances.
* Key/Legend: Explanations of symbols and markings used on the map.
O.S. maps are widely used for:
* Navigation: For hikers, walkers, cyclists, and anyone exploring the UK.
* Planning: For construction, development, and other projects.
* Research: By historians, geographers, and other academics.
If you see a map with the "O.S." abbreviation, it means you're looking at a map produced by the official mapping agency of Great Britain.
