We have a special new map in the Geography Department, which was made using the Ordnance Survey's Custom Map service. This has been around for some time now, and allows users to create maps which are either flat or folded, with a title and image of their choice. I've got one centred on my village which I won in an OS competition.
We ordered one at the weekend and it arrived within a few days - very quick service. The map is centred on King's Ely, which is great because the school sits right at the edge of the actual map sheet, so it's not very easy to see the surrounding geography. We'll be using it for our new Fentastic Geography unit in the Michaelmas term too.
Why not order one for your department?
