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).

[1] Three model versions have been published: EGM84 with n=m=180, EGM96 with n=m=360, and EGM2008 with n=m=2160. n and m are the degree and orders of harmonic coefficients; the higher they are, the more parameters the models have, and the more precise they are. EGM2008 also contains expansions to n=2190. [1]
