Merriam – Webster dictionary defines a map in three ways, the first, “a representation usually on a flat surface of the whole or a part of an area” second, “a representation of the celestial sphere or a part of it,” and third, ” a diagram or other visual representation that shows the relative position of the parts of something”
The word ‘map’ comes from a Latin word, ‘Mappa Mundi’ which had two meanings, Mappa, meaning cloth or sheet, and Mundi, meaning ‘world’ The literal translation of ‘Mappa Mundi’ was. “sheet of the world.” The word ‘map’ is a shortened derivative that means a two-dimensional representation of the earth’s surface.
A map is a symbolic depiction of different objects, regions, themes, features and the like. Most Maps are static, meaning they are fixed on paper. Technology has made most maps interactive. You can manipulate and use them to scour for different information.
Maps are mostly geographical depiction of physical features. They can also be used to represent nonphysical information, like DNA and brain mapping. Spaces being mapped can be two dimensional e.g the earth’s surface or three dimensional like in the earth’s crust.
Physical maps show the earth’s features, like landscapes, mountains, rivers, valleys, deserts, lakes and oceans. They can also be used to show elevation, land use, infrastructure, and many other man-made features. Physical maps that show boundaries are also known as political maps.
Modern maps apply GIS (Geographic Information Systems) used in industries as diverse as agriculture, Disaster management, disease control and many more. The effectiveness of GIS maps is based on Algorithms, Satellite sensing, and Machine learning, to capture analyze and integrate georeferenced and geospatial data.
