As applications of geospatial technologies continually break down disciplinary barriers, the need for books on these technologies to reach diverse audiences is greater than ever. The challenge, however, is to write a book on this complex topic that integrates knowledge from multiple disciplines and makes it useful to those who may or may not have diverse educational backgrounds, but who need to use these technologies. Most books on geospatial technologies are aimed at a specific audience. In contrast to this, geographic information science attempts to target three different audiences (users, students, and engineers) using formats and languages ​​that suit them. While this effort is laudable, it is difficult to maintain balance and appeal to all three audiences. The author, Narayan Panigrahi, has managed this balancing act, but with mixed results. His background in computer science is clearly visible in the structure and content of the chapters. This book is another addition to the list of introductory GIS textbooks. The book focuses on topics that should typically be learned in an introductory GIS course. The author infuses mathematical equations and formulas throughout the book to explain GIS tasks. This is helpful for the student to learn the basics of GIS rather than just learning GIS software. Aside from occasional typographical errors and incomplete sentences, the chapters are generally readable and contain several flowcharts, images, and the price of the book is moderate. Each chapter ends with study questions and references. The author has tried to organize the chapters according to formats of “input-processing-output model”, “model-view-control process” or “information function use case”. In the middle of the article, GPS is considered an indispensable element of GIS. Discussions of cartographic principles, commercial GIS software, satellite images, aerial photos, and geodatabases are some of the other glaring omissions from this book. There is an inconsistency in the depth of topics explored; for example, map projections are explored in depth, while vector topology is simply glossed over. These omissions and inconsistencies would, in my opinion, make this book slightly less beneficial for all three audiences combined. However, there is something for everyone; structure for engineers, equations for engineers and students, and GIS concepts for students, engineers, and users. This book will therefore be undeniably valuable if used to supplement the material in some of the other foundational GIS books in the discipline. This has merit, but there is room for improvement.
