Remote sensing has been defined as the detection, recognition or evolution of objects by means of distant sensing or recording devices. Historically, it developed quickly from technology of aerial photo-interpretation science. In recent decades, remote sensing technology has emerged to support data collection and analysis methods of potential interest. Besides, it holds importance for forest management and many other fields. Remote Sensing and Geographical Information Systems (GIS) deal with mapping technology, concepts of maps and all relevant terminology, which are necessary for the beginners to develop their skills in this new and upcoming technology. This book provides basic principles and techniques of remote sensing, microwave remote sensing, remote sensing platforms and sensors and data analysis techniques. Further, the book also covers GIS data quality issues, GIS data analyses and modelling, attributes of data management, GIS data input and editing, integration and linkage of remote sensing and GIS. The subject matter of the book has been divided into 23 chapters to provide focused attention to each aspect of remote sensing"from fundamental considerations and processes"to electromagnetic radiations, their properties and applications"to observation satellites and hydrospheric sciences. An exclusive chapter has been devoted to natural hazards. All natural hazards are amenable in some degree to study by remote sensing because nearly all geologic, hydraulic and atmospheric phenomena that create hazardous situations are recurring events or processes that leave evidence of their previous occurrence. This evidence can be recorded, analysed and integrated into the planning process. All the topics have been covered in a cogent and lucid style to help the reader grasp the information quickly and easily. Glossary and Index have been provided at the end for quick reference. Diagrams, figures and tables supplement the text. The book is essential reading for all students and teachers of geology, earthquake engineering, life sciences, biotechnologies, bioinformatics, environment science, and research scholars in remote sensing and allied fields. About Author: S.C. Bhatia, a Chemical Engineer from BITS, Pilani and also an MBA, is a consultant on Environmental and Pollution Control, Energy Conservation and Polymer Sciences.
