Symbology may be implicit, using universal ...
National atlases in Europe are typically printed at a scale of 1:250,000 to 1:500,000; [a] city atlases are 1:20,000 to 1:25,000, [b] doubling for the central area (for example, Geographers' A-Z Map Company's A–Z atlas of London is 1:22,000 for Greater London and 1:11,000 for Central London).
