Information technology is an umbrella term that includes sets of tools, processes, and methodologies with associated digital equipment to collect, process, and present information. Over the course of past several decades, information technology has been expended by various principal technologies to input, process, output, and distribute the information around the globe. Information technology and the informatics wave have touched shores of every sphere of human life, making it simpler and sophisticated at the same time. This information technology revolution has been a catalyst for the metamorphosis of isolated into a global connected village.
Digital technologies are now part of our everyday work. Today, innovations in information technology are facilitating wide-ranging impacts across numerous domains of society. Various digital revolutions and technologies have proliferated the pre-mechanical, mechanical, electromechanical, and now electronic phase of information technology. The inherent presence of informatics in the fabric of our lives is also so intricately interwoven that at times we find it difficult to imagine a life without it. In the present times, a life without mobile seems a far- fledged possibility, but this was not the case 20 years ago. Geographic information system, or GIS as it is called, is one such technology, which is in its initial stage; soon it will catch up and integrate into our day-to-day activities. It is an information system that has the potential to organize complex interrelation between different layers of information through the process of gathering, analysing, processing, storing, and presenting spatial data and images available through different sources.
