The terms are sometimes used in the absolute sense of the table, but other times in a relative sense. For example, a map reader whose work refers solely to large-scale maps (as tabulated above) might refer to a map at 1:500,000 as small-scale. In the English language, the word large-scale is often used to mean "extensive".
In most European countries, the largest scale topographic map series is a 1:25.000 scale series. Notable exceptions are Austria (1:50,000) and Finland (1:20,000). Many non-European states limit the largest scale of their map series, usually to 1:50,000 scale, frequently due to the large size of the country covered (and hence for financial reasons).
The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale. In most projections, scale varies with latitude, so on small scale maps, covering large areas and a wide range of latitudes, the linear scale must show the scale for the range of latitudes covered by the map. One ...
This rule is derived from the equivalent of 0.5 mm on a map, the smallest physical mark that a cartographer can make: - Map Scale = Raster resolution (in meters) * 2 * 1,000 or - Raster resolution (in meters) = Map Scale /(2 * 1,000) By example, if the image resolution is 5m only the map scale should not be larger than 1:10,000.

Most often, generalization starts with detailed data created for a larger scale, and strategically removes information deemed to be unnecessary for a smaller scale map. This issue assumes more importance as the scale of the map gets smaller (i.e. the map shows a larger area) because the information shown on the map takes up more space on the ...
The design may have inspired later 'Maps of World History' such as the HistoMap by John B. Sparks, which chronicles four thousand years of world history in a graphic way similar to the enlarging and contracting nation streams presented on Adam's chart. Sparks added the innovation of using a Logarithmic scale for the presentation of history.
Many maps are drawn to a scale expressed as a ratio, such as 1:10,000, which means that 1 unit of measurement on the map corresponds to 10,000 of that same unit on the ground. The scale statement can be accurate when the region mapped is small enough for the curvature of the Earth to be neglected, such as a city map .
