“Geographic Information Systems (GIS) is a modern and effective technology to address developmental issues. All over the world, it is extensively used for resource management, environmental issues and policy decisions support systems with increasingly wider applications in agriculture, water resources development & management, veterinary sciences to disaster management. Being a new and interdisciplinary in nature, this interesting subject requires a lot of introductory textbook to improve understanding of the students. The author has put his teaching and research experience into good use and has brought out this concise and very readable book. With topics like: Hardware, software & liveware, recent developments Spatial and Map Projections and Database management, modeling, structuring, Networking, conversion and quality aspects finding their way in this book, which makes it worth reading for not only students but also for the teaching fraternity.”
