The Ordnance Survey Blog has the first of a three-part series that takes a behind-the-scenes look at the OS’s cartography team. The team, says the blog, is “responsible for deriving and maintaining cartographic databases, and providing the finished data for Ordnance Survey national series paper and data products. They do this through the manipulation and enhancement of our core databases. But as well as this ‘core’ work, they work on lots of other projects from specialist maps to innovative work on the effects of colour vision deficiency on mapping.”
