Mathematical morphology in geomorphology and GISci
Sagar B., Chapman & Hall/CRC, Boca Raton, FL, 2013. 546 pp. Type: Book (978-1-439872-00-0)
Date Reviewed: Nov 18 2013

This work was written by a well-known geomorphology expert, Daya Sagar, for other geomorphology experts. Therefore, if you are not a part of that group, then this book is probably not for you. Knowledge in geomorphology and geographic information systems (GIS) is required to be able to follow the material.

Chapter 1 summarizes the content of the book. Chapter 2 introduces all the formulas for the mathematical morphology. The author describes every operator in detail, with many examples. Some readers might find the structure of this chapter confusing, but the explanations and descriptions are of very high quality.

A general description of the datasets used in the book is given in chapter 3, and several different real-world geographic environments are discussed in detail. In the following chapters, the author shows how mathematical morphological operators can be used to obtain several different geomorphologic and geographic features, such as mountains, basins, and ridges. The author assumes that the reader is an experienced geomorphologist, familiar with this subject (GIS), who might want to learn more about using mathematical morphology for related tasks. However, I found these chapters very dense and hard to follow. Furthermore, the structure of these chapters is not always clear and sometimes the author seems to go back and forth between concepts, which can make the reading somewhat uncomfortable for any reader.

The book does include extensive documentation and numerous references for further reading. I note that many of the references are by the author of this book and his colleagues. While this provides evidence that Sagar is really an expert in the field, it seems that including references from other researchers might broaden the scope for further reading to resources with different points of view.

Unfortunately, the book has been published in grayscale. In this type of book, color images are almost mandatory. Color illustrations would have helped me better comprehend the material. The geographic images introduced in chapter 3 and used throughout the book should have appeared in color for improved understanding.

Overall, this book provides solid information about using mathematical morphology for geographic imaging from a real expert in the field. Because of the level of expertise required, the book is suitable only for proficient geomorphologists. Novices in this field should not start with this book.
