REMOTE SENSING GIS AND GPS: PRINCIPLES AND APPLICATIONS

The fields of Remote Sensing, Global Positioning System (GPS), and Geographic Information Systems (GIS) have witnessed remarkable growth in recent decades, establishing themselves as essential technologies for scientific research, environmental management, infrastructure development, and sustainable planning. Their ability to provide accurate, reliable, and timely spatial information has made them indispensable in addressing challenges such as climate change, urbanization, natural hazards, and resource management. This textbook, Remote Sensing, GPS and GIS: Principles and Applications, has been prepared with the objective of presenting the fundamental principles and practical applications of geospatial technologies in a clear and systematic manner. The contents of the book are structured to cover the physics of remote sensing, sensor platforms, data acquisition methods, digital image processing, GPS fundamentals, and GIS concepts including spatial analysis, data integration, and modeling. The integration of these three domains is highlighted through case studies and applications in agriculture, forestry, hydrology, disaster management, and urban planning. The book is intended to serve as a comprehensive resource for undergraduate and postgraduate students in engineering, environmental sciences, geography, and allied disciplines. It is also expected to benefit researchers, academicians, and practitioners seeking to apply geospatial technologies in their respective fields. To facilitate learning, the text is supported by illustrations and diagrams that bridge theoretical concepts with real-world practice.
