Geographic Information Systems (GIS) is a cutting-edge technology that has proven to be highly effective in addressing developmental challenges. Its extensive use in resource management, environmental issues, and policy decision-making support systems has led to increasingly wider applications in various fields, such as agriculture, water resources development and management, veterinary sciences, and disaster management. As a relatively new and interdisciplinary subject, there is a growing need for introductory textbooks that can enhance students understanding of the subject. The author of this book has drawn upon his teaching and research experience to produce a concise and highly readable text that covers a range of topics, including hardware, software and liveware, spatial and map projections, database management, modeling, structuring, networking, conversion, and quality aspects. This makes the book a valuable resource not only for students but also for the teaching fraternity.
