Overview of the book

Remote sensing is a mechanism for collecting raster data or images, and remotely sensed images represent an objective record of the spectrum relating to the earth surface materials. Information extraction from physical properties and chemical composition of the those images is, on the other hand, an entirely foci will derive very different thematic information subjective process.

As illustrated in Fig. 0.1, our the management, display and analysis of all kinds of spatially referenced information. Remote sensing, image processing and GIS are all extremely broad subjects in their own right; far too broad.

The application cases are biased toward the earth sciences but the image processing and GIS techniques are book is aimed at the overlap between the three disciplines, providing an overview of essential techniques and a selection of case studies in a variety of application areas, emphasizing the close relationship between them.generic and independent of any software, and therefore and with conceptual illustrations. For image processing transferable skills suited to all applications.The book has been written with university students and lecturers in mind as a principal textbook. For students’ needs in particular, we have tried to convey knowledge in simple words, with clear explanations much mathematical detail. The result is intended to be and GIS, mathematics is unavoidable, but we understand that this may be off‐putting for some. To minimize such effects, we try to emphasize the concepts, explaining in common sense terms rather than in too a comprehensive yet ‘easy learning’ solution to a fairly challenging topic. 

There are sections providing extended coverage of some necessary mathematics and advanced materials for use by course tutors and lecturers; these sections will be marked as such. Hence the book is written for both students and teachers. With many author‐developed techniques and recent research case studies, it is also an excellent reference book for higher level readers including researchers and professionals in remote sensing application sectors. In this book, we have presented a unique combination of tools, techniques and applications that we hope will be of use to the full breadth of geoscientific and remote sensing communities. 

The book begins with the fundamentals of the core image processing tools used in remote sensing and GIS with adequate mathematical details in Part I, then it becomes slightly more applied and less mathematical in Part II to cover the wide scope of GIS where many of those core image processing tools are used in different contexts. Part III contains the entirely applied part of the book, where we describe a selection of cases where image processing and GIS have been used, by the authors, in teaching, research and industrial projects in which there is a dominant remote sensing component. Since the publication of the first edition in 2009, we have been pleasantly delighted and encouraged by the interest in this book, and comments from students and colleagues alike have stimulated us to produce this second edition. 

In making the explanations of the book generic and not tied to any particular software, we attempted to ‘future‐proof’ its content in the first edition. Inevitably, however, there are many small things that have needed to be updated in this second edition. We have implemented minor updates to all the main chapters in Parts I and II. A completely new chapter on sub‐pixel technology and image phase correlation has been added in Part I (Chapter 11), which is based on new and ongoing research in this area. Part  III has been considerably enhanced with more recent case studies to include new data and/or other new complementary research where relevant. We also take this opportunity to acknowledge the many data sources that we have made use of in this book. These include NASA’s 40‐year Landsat archive (without which much of our daily work would be impossible), ESA radar image archive (ERS and Envisat), Aster GDEM and SRTM global elevation data, ESRI’s online knowledge base, and the NERC (Natural Environment Research Council, UK) airborne campaign (Airborne Thematic Mapper). Images are both the principal input and product of remote sensing and GIS, and they are meant to be visualised! The e‐version of the book therefore now contains hyperlinks to high resolution digital versions of the images and illustrations, allowing the reader to examine the details at pixel level and to appreciate the effects of particular processing techniques such as filtering, image fusion, and so forth.
