The foundations for quantitative map scaling goes back to ancient China with textual evidence that the idea of map scaling was understood by the second century BC. Ancient Chinese surveyors and cartographers had ample technical resources used to produce maps such as counting rods, carpenter's square's, plumb lines, compasses for drawing circles, and sighting tubes for measuring inclination.
The detailed scale bar in two measurement systems facilitates precise distance measurements by an international audience, which may or may not be the intent. Map layout, also called map composition or (cartographic) page layout, is the part of cartographic design that involves assembling various map elements on a page. This may include the map ...
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 ...
During the first half of the 20th century, cartographers began to think seriously about how the features they drew depended on scale. Eduard Imhof, one of the most accomplished academic and professional cartographers at the time, published a study of city plans on maps at a variety of scales in 1937, itemizing several forms of generalization that occurred, including those later termed ...
The small scale map series are edited by the Federal Agency for Cartography and Geodesy. 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).
All maps portray a small, strategic sample of the infinite amount of potential information in the real world; the strategy for that sample is largely driven by the scale, purpose, and audience of the map. [22] The cartographer is thus constantly making judgements about what to include, what to leave out and what to show in a slightly incorrect ...
Cartographic scale or map scale: a large-scale map covers a smaller area but embodies more detail, while a small-scale map covers a larger area with less detail. Operational scale: the spatial extent at which a particular phenomenon operates. E.g. orogeny operates at a much larger scale than the formation of a river pothole does.
This map's significance draws from historical misconceptions of East Asian cartography, the main one being that East Asians did not do cartography until Europeans arrived. The map's depiction of trading routes, a compass rose, and scale bar points to the culmination of many map-making techniques incorporated into Chinese mercantile cartography.
