Maps of Britain

There now many sites that feature maps. This one is from the Ordnance Survey and so the maps are of high quality. Just put in the postcode and up comes the map, and you can zoom in and out. It will make a superb teaching aid and the zoom technique means that it is very easy to put an area into context, something that is not easy to do with the paper versions.
