This book is the main text for an undergraduate course in GIS in my university department. The book serves as a nice introduction to some fundamentals of GISs and does a particularly good job at linking the theoretical constructs and concepts with specific application domains. There are many examples of the applicability of the theories on specific industrial and governmental projects.

Chrisman is a gifted author and provides a refreshing perspective of how to think about geographic information systems. It all starts rather abstractly with levels of measurement, reference systems and measurement frameworks. Choices in these levels turn out to be what dictates the adoption of field vs. object data models (the classic dichotomy in GISs) and raster vs. vector structures consequently. The author then proceeds in exposing operations of increasing complexity on these structures, and does a very systematic work on categorizing them. A plethora of diagrams, figures, and footnote-definitions of important terms complement the text nicely. The final chapters on the ties of GISs with society and culture are also very interesting. The whole book has a flow and a strong structure, a feature that I value especially in technical books. There are no loose chapters and everything builds on what has been discussed before.

Of course as an introductory textbook it leaves out some areas of investigation and comments only scarcely on others. For example the chapters on comprehensive operations and transformations are just very generic overviews. Models such as spaghetti or topological database structures are also very superficially presented, hence the 4-star rating.

Overall, a very interesting, clearly written, and consice introduction to GISs.
