A small-scale map cover large regions, such as world maps, continents or large nations. In other words, they show large areas of land on a small space. They are called small scale because the representative fraction is relatively small. Large-scale maps show smaller areas in more detail, such as county maps or town plans might. Such maps are ...
Scale is important to include on a map because it explains the size relationship between map features and the real world. Scale is commonly represented with a scale bar, a representative fraction ("1:100,000"), or a verbal scale ("1 inch = 1 mile"). [14]
The vertical exaggeration is given by: = where VS is the vertical scale and HS is the horizontal scale, both given as representative fractions.. For example, if 1 centimetre (0.39 in) vertically represents 200 metres (660 ft) and 1 centimetre (0.39 in) horizontally represents 4,000 metres (13,000 ft), the vertical exaggeration, 20×, is given by:
The fraction expressing the ratio between the distance measured between two points on a map and the corresponding actual distance measured between those points in the real world, used to indicate the map's scale. The fraction's numerator is typically 1 (indicating one of some specified unit of length, e.g. inches or centimetres) and the ...
In geography, scale is the level at which a geographical phenomenon occurs or is described. This concept is derived from the map scale in cartography . Geographers describe geographical phenomena and differences using different scales.
