The final map needs to be drawn with sufficient accuracy so that a feature shown on the map can be identified clearly on the ground by the competitor, thus, field-workers need to locate features with a high level of accuracy, to ensure consistency between map and terrain. Where the map and terrain are inconsistent, the feature becomes unusable ...
Orienteering is a group of sports that involve using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map , usually a specially prepared orienteering map , which they use to find control points . [ 1 ]
Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography , and as such its portrayal presents a central problem in cartographic design , and more recently geographic ...
Land navigation is the discipline of following a route through unfamiliar terrain on foot or by vehicle, using maps with reference to terrain, a compass, and other navigational tools. [1] It is distinguished from travel by traditional groups, such as the Tuareg [ 2 ] across the Sahara and the Inuit [ 3 ] across the Arctic , who use subtle cues ...
Political map of Europe, showing south at the top. Research suggests that north-south positions on maps have psychological consequences. In general, north is associated with richer people, more expensive real estate, and higher altitude, while south is associated with poorer people, cheaper prices, and lower altitude (the "north-south bias").
Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. Represent the terrain of the mapped object on flat media. This is the concern of map projections.
When and how the earliest maps were made is unclear, but maps of local terrain are believed to have been independently invented by many cultures. The earliest surviving maps include cave paintings and etchings on tusk and stone. Maps were produced extensively by ancient Babylon, Greece, Rome, China, and India.
