"Remote sensing is the art and science of obtaining information about an object without being in direct physical contact with the object. It can be used to measure and monitor important physical and biophysical characteristics and human activities on Earth. This book on Fundamentals of Satellite Remote Sensing and Aerial photographs is written to introduce the reader mainly to:
The characteristics of electromagnetic radiation and how the energy interacts with Earth surface materials such as vegetation, soil, rock and water,how electromagnetic energy reflected or emitted from these materials isrecorded using a variety of remote sensing instruments (e.g., cameras,multispectral scanners, hyperspectral instruments, RADAR), and how we can extract land use/land cover information from the remote sensor data to solve important problems.
The book introduces the principles of visual photo-interpretation and also the technique of image analysis. It also tries to give methods of extracting quantitative information from vertical aerial photographs.
Unique properties of remote sensor data are reviewed. The fundamental techniques of image interpretation are described. The power of three dimensional depth perception is explained.
The information `on Aerial photography and Photogrammetry provided is mainly based on the knowledge acquired during training in aerial photo interpretation at Dehradun.
We are sure that the book will be of immense use to all those interested in the field of Satellite remote sensing."
