Correct Answer Is Option = Cartography
Notes / Explanation
The study or science of making maps is called cartography, and it is a field that combines elements of geography, art, mathematics and, in modern times, advanced technology. A map is a representation of the Earth's surface, or a part of it, drawn on a flat surface according to a particular scale, and cartography is the discipline concerned with the design, production and study of such maps. Maps have been used by human beings for thousands of years, because they allow people to understand and record the layout of the land, to find their way from one place to another, and to communicate information about the world in a clear and visual form. In ancient times, maps were drawn by hand based on the observations and travels of explorers, sailors and scholars, and although they were often inaccurate by modern standards, they represented remarkable achievements for their time and reflected the knowledge and beliefs of the societies that produced them. The work of a cartographer involves carefully gathering information about the features of the land, such as mountains, rivers, coastlines, cities and roads, and then representing these features accurately on a map using symbols, colours, lines and labels. One of the central challenges of cartography is the problem of representing the curved surface of the spherical Earth on a flat sheet, which always involves some degree of distortion, and cartographers use various techniques and projections to manage this problem according to the purpose of the map. Maps can be made for many different purposes, including political maps that show countries and boundaries, physical maps that show natural features, climate maps, road maps and many specialised maps used in fields such as planning, navigation and resource management. In the modern era, cartography has been transformed by the development of satellite imagery, aerial photography and computer-based geographic information systems, which allow maps to be produced with extraordinary accuracy and detail and to be updated quickly as conditions change. These technologies have made maps more useful and accessible than ever before. For PPSC and other competitive examinations, the key points to remember are that cartography is the science and art of making maps, that it involves representing features of the Earth's surface on a flat surface using scale and symbols, and that modern cartography relies heavily on satellite imagery and computer technology.
