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 of these is shown below. Since most nautical charts are constructed using the Mercator projection whose scale varies substantially ...
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 ...
For example, the answer to the famous question "How Long Is the Coast of Britain" is highly dependent on the choice of cartographic scales. In cartography and spatial analysis , scale effect and zoning effect (different ways of zoning lead to different statistical outcomes) combined can lead to modifiable areal unit problem (MAUP).
The coastline paradox is often criticized because coastlines are inherently finite, real features in space, and, therefore, there is a quantifiable answer to their length. [ 17 ] [ 19 ] The comparison to fractals, while useful as a metaphor to explain the problem, is criticized as not fully accurate, as coastlines are not self-repeating and are ...
The continental scale level refers to a continent; The global scale applies to the entire world; The fluvial scale level relates to river basins (this scale level is mainly used in the context of pollution, for example). Global and continental scale: the world with continents. National and regional scale:The United States with all the states ...
Generalization: All maps must be drawn at a smaller scale than reality, requiring that the information included on a map be a very small sample of the wealth of information about a place. Generalization is the process of adjusting the level of detail in geographic information to be appropriate for the scale and purpose of a map, through ...
Scale (geography) Weighing scale, an instrument used to measure mass; Scale (ratio), the ratio of the linear dimension of the model to the same dimension of the original; Spatial scale, a classification of sizes; Scale ruler, a tool for measuring lengths and transferring measurements at a fixed ratio of length; Vernier scale, the scale on calipers
Issues such as smaller-scale maps (whole country) vs. larger-scale maps (city) take the map projection as a given. In the whole thematic mapping business, point or localized scale is only treated marginally when recommending the adoption of an equal-area projection -- so only areal scale is considered, linear scale is not even mentioned.
