Reading the messageboard, it seems all about satnav, geo-location and whatever these days, which to me is very sad as it takes away the need for maps (or does it?). Give me and A-Z or an OS (Ordnance Survey) map any day over these false Gods! But as someone who left school when they were still giving out milk, can I ask anyone here who either teaches or has left school recently, do they still teach "how to read/use a map" including grid references? Anyhow, OS maps are clearly my favourite paper maps, on-line I don't really have a favourite as different maps (eg google, openstreetmap, streetmap, topographic-map.com) each have their own qualities depending on what you are using them for. Of course all you rail enthusiasts will know of and love the rail maps shown in http://www.projectmapping.co.uk and there are various other rail atlases out there. So just starting a thread to answer the question above and to fight back against satnav and it's friends!!
