Bicycle Maps

From the earliest days of mankind, people have created maps. At the beginning very simple and later more and more complex.

A map is a simplified representation of a space which highlights relations between components (objects, regions) of that space. In most cases, a map is a two-dimensional geometric representation of a precise three-dimensional space, for example, a map. More generally, maps can be designed to represent the local properties around the world or in part, or any other area, like the brain.

Map-making dates back to the stone age and appears to predate written language by several millennia. One of the oldest surviving maps is painted on a wall of the Catal Huyuk colony in south-central Anatolia (now Turkey), he goes back to about 6200 BC. One who makes maps called private or professional cartographer.

Maps are abstract representations of the world. It is, of course, this abstraction that makes them useful. Lewis Carroll made this point humorously in Sylvie and Bruno with his mention of a fictional map that had "the scale of a mile of the mile. A character notes the practical difficulties of this map and stated that "we now use the country itself as its own map, and I assure you it does nearly as well." This concept is developed through a history of a paragraph by Jorge Luis Borges, generally known in English as "On the accuracy in science".

Road maps are perhaps the most widely used maps today, and form a subset of navigational maps, which also include aeronautical and nautical charts, maps, railway network, and tourist maps and cycling. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, conducted by municipalities, utilities, evaluators, providers of emergency services, and other local organizations. Many national surveying projects have been undertaken by the military, like the UK Ordnance Survey (now a civilian government agency internationally renowned for his detailed work complete).

Many, but not all cards are on a scale, allowing the reader to deduce the size of, and distances between objects represented. On a larger scale shows more detail, which requires a larger map to show the same area. For example, maps designed for the walker is often reduced at a rate of 1:24,000, which means that 1 of any unit of measurement on the map corresponds to 24,000 of the same unit in reality, while maps designed for motorist is often reduced to 1: 250,000. Maps which use some quality other than physical area to determine relative size are called cartograms.

A famous example of a map without scale is the London Underground map, which best fulfills its purpose by being less physically accurate and more visually communicative to look forward to the suburbs. This is not an anamorphic (since there is no uniform measure of distance) but a topological map which also represents the approximate bearings. The simple maps shown on some directional road signs are further examples of this kind.
