The Beauty of GIS

Geographic Information System is a powerful computer system that allows business to be more competitive than ever before. The idea behind GIS is to make geographical information available at the fingertips to the users of the technology. Knowing the necessity of this tool, this article is designed to give a better understanding of Geographic Information System GIS.
GIS has four interactive components: an input subsystem for converting into digital form (digitizing) maps and other spatial data; a storage and retrieval subsystem; an analysis subsystem; and an output subsystem for producing maps, tables, and answers to geographic queries. GIS is frequently used by environmental and urban planners, marketing researchers, retail site analysts, water resource specialists, and other professionals whose work relies on maps. GIS also helps in decision making about where might be a potential risk for businesses.
The use of GIS for your business idea will help you to be on top of the core competition. “It facilitates modeling of processes in both space and time and has been the focus of much research investment. It has a massive range of potential applications in a wide range of areas, such as the planning of public facilities” (Britannica). “GIS represents points as individual, uniform chunks of the Earth, usually squares, called grid cells. Collections of grid cells represent lines and areas” (Michael N. DeMers).

Instruction in GIS operation and use is now a core component of many degree programs. Many universities offer specialist qualifications in GIS and conferences of GIS users are by far the largest regular gatherings involving geographers. To some this modern expression of cartography comprises a geographic information science, part of a larger field of geoinformatics; it provides many geography graduates with a heavily demanded key skill, and its research and applications potential offers a secure foundation for the discipline's future.
