Why are they important? Q4. Explain supervised and unsupervised classification. Compare their advantages/disadvantages. Q5. Write a note on applications of remote sensing in agriculture and forestry.
The book is primarily written for , specifically those pursuing degrees in:
A unique aspect of this remote sensing book is the integration of directly into the chapters. The subtitle often includes "with Practical Exercises." Every chapter concludes with a "Meenakshi Work Lab" – a hands-on exercise that uses freely available data. remote sensing book by meenakshi work
All remote sensing relies on detecting energy. The book systematically explores how the sun serves as the primary energy source for passive sensors, emitting waves across the electromagnetic spectrum. It outlines the differences between: A Short Guide to Remote Sensing - Cognitive Space
The book begins with the "why" and "how" of remote sensing. Define remote sensing

For students, researchers, and practitioners navigating this technical labyrinth, the scholarly work of —most notably her comprehensive texts on Remote Sensing—has served as an essential compass. Her writing does not merely explain how to look at the Earth from above; it teaches us how to understand it.
: The book explains how this "view from above" is used practically in areas like: Agriculture : Monitoring crop health and predicting yields.
