We'd like to use analytics cookies to understand which symbols people look up, so we know what to research next. They are not used for advertising and we set none of them unless you say yes. What we store.
Symbols read while finding the way, grouped because they look alike and their authority could hardly differ more. Nautical chart symbols are agreed internationally through the IHO, because a chart misread at sea is a different kind of error. National mapping agency symbols are official within one country and meaningless across a border. Compass roses, map pins and waymarking are conventions nobody defines. Each record states which it is, because a walker trusting a symbol with an authority it does not have is the failure this group exists to prevent.
