The Evolution of GIS - Essay Exampleterature on this subject, it is clear that these two are the core components of the dodge and the manner by which they rapidly evolve has driven the pace by which GIS has changed and will change oer time. This is supported by the evidences that follows. Essentially, GIS is defined as the trunk of computer hardware, software, personnel, organizations, and business processes designed to support the capture, management, manipulation, analysis, mannikin and display of spatially referenced data (TRB, p.10). As with any type of computing technology, the GISs own system is consisted of three basic parts, namely, the UI or the user interface, the woodpeckers, which is differentiated according to functions, and, finally, the data manager. Put in some other way, the components of the system can be said to include data, technology, application and humans (Lloyd and Bunch, 2003, p.828). All of which have their single and equally important functions. Whil e the GIS could run in a single computer terminal, the optimum mannikin requires several computers for GIS operations - desktop, client server, centralized desktop and centralized server (Longley et al. 2005, p.158). These variables and operational framework emphasize why hardware and software are critical in the progression of the GIS development. Hardware The invention of the atomic number 14 chip back in the 1970s launched the fast paced computer development (Pasewark and Pinard, 2007, p. 263). It led to the viability of personal computers, which became the harbinger of the current technology typified by smaller, faster, powerful and cheap hardware. To put this environment in context, there is the so-called Moores Law which states that computer processing chips double in power almost every 18 months, making computer more... Thi essay stresses that the growth of the GIS system can be attributed to several important technological developments. First, there are the advances in computing hardware, which made computers affordable and powerful. Today, many people and organizations can pervert desktop systems not just in workplaces but even for home use. These are computers that can fare complicated tasks and functions with apparent ease.This report makes a conclusion that in order to depict the significance of the evolution of GIS in the past twenty years, it is important to go back to the importance of geographic information. Accurate and authentic geographic data do not only mean effective geographic expeditions or demesne mapping initiatives. Rather, they are imperative in many other endeavors such as in running play a city or in predicting a catastrophe. This is the reason why GIS is an important technological tool and how its evolution should be of interest for people. In the past twenty years, there were significant achievements and the evolutionary route points to a more sophisticated and intuitive system that would help people to make sense not just of the Earth but also beyond. It is worth noting that today there are just numerous geographies or approaches to geography. One of GIS greatest contributions, as evidenced by its evolution, is the universalization and consistency of geographic information.
