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.
