  1. Amazing! Thanks for this extremely practical video. Also, as an American, I am very jealous of the level of detail and the number of specific symbols on OS maps. Here in the U.S. we are often lucky to get a simple dot for a footbridge or a trail junction and we are left to discover what the dot represents. I suppose it keeps our sense of adventure alive, but in certain circumstances it would be extremely helpful to have more information rather than less.

  2. Wayne, is there a link that you could share where I could purchase a copy of a map of the UK? I find it very fascinating!! Can you help me? From Washington State 💯❤️👍🏽🇺🇸

  3. Great refresher and some good info around stuff. Couple of little typos if I may – Windmill picture shows motorway text and the spelling of station otherwise 👍🏻

  4. Wow Wayne, thank you! Very detailed. That must have taken you a while to create! I don't think there is anything like this on YT 🎉. I appreciate your time doing this for us – your fans. ❤

  5. Holy Molly, talk about bureaucratic congestion. In Canada, we have far less data; perhaps they figure we should explore more for ourselves without hand-holding. Hazards, and predominant features are shown, but not every stone.

  6. Very informative many thanks. Can you clear up one thing for me? What is a pale blue cross that appears on my old 50k map but missing on the newer version? I think it has something to do with the grid but can't work out what, they appear anyway on the map both land and sea.

  7. I don’t live in the UK but find all your videos very informative and the waffles are a brilliant bonus. Maybe if I ever do get to visit your beautiful country and walk in these everyday, yet historic paths, I’ll be able appreciate things all the more. Cheers.

  8. Map symbology is one of the things I find most fascinating about cartography!
    You can practically read an interesting map like a human and geologic history book. Everything drawn is there for a reason. A story told by the cartographer in an almost hyrogliphic language, few will take the time to learn.

  9. Very informative video Wane, thanks for taking the time to make it. Just imagine the design work and thought that the people at OS have put into creating the various symbols and line types, presumably refining them over the years. Not only that but also the placing of the symbols and text so that they do not obscure or clash with other entities in the surrounding location on the map and ensuring that they are readable.

  10. I wonder, are some traffic jams permanent enough to be put on maps? („It is not a transportation system, it’s a storage system.“ Starship Titanic by Terry Jones, after Douglas Adams‘ game)
