Designed for a comprehensive coverage of GIS topics, this book is in three parts. Part 1 covers the fundamentals of GIS including co-ordinate systems, data models, data input, data display and data management. Part 2 includes data exploration, analysis using vector and raster data, and terrain analysis. Part 3 covers spatial interpolation, GIS modelling, regions, and network and dynamic segmentation. Also included are new developments such as the object-oriented model and research-oriented questions, like the effect of spatial scale. Concepts from fields such as geography, cartography, spatial analysis and database management explain the purpose and objectives of GIS operations and the interrelationship between them. Each chapter is divided into two main sections, the first one covering topics and concepts, and the second dealing with applications, usually with three to five problem-solving tasks. To include data sets and instructions for the practice sections, we chose GIS packages as examples for this book, and ArcView software is included.
My main complaint about Introduction to Geographic Information Systems is it's about the driest textbook I have ever read, and I have read hundreds throughout my undergrad and grad degrees. It is essentially a reference book organized like a textbook. Chang has no style to his writing. Every section is written like a dictionary entry. Every sentence follows a straight-forward structure. If AI had written a textbook on GIS and was given a dictionary as the only reference for how human speech and sentence-structure are patterned, it would very much resemble this book. As much as I love the written word, I'm not sure a book is the best way to present this material. A series of videos might be a better way of communicating GIS, which, after all, is a visual tool.
I give the book two stars rather than one because I think to certain users it probably is a helpful book. It appears to cover every aspect of GIS, even if not in the most compelling manner. If you were a semi-experienced GIS professional, having this book as a reference may be handy. Having said that, for a book with "Introduction" in its title, you're expected to have substantial background knowledge, especially in geography. Between this and the dry style, Chang doesn't show much empathy for his readers.
This review wouldn't be complete without mentioning the price and format of the book. I realize this is left up to the publisher, but this is a clear case of gouging customers because they need it for a professional course. The textbook costs $222 on Amazon for the ebook, only slightly cheaper than the list price for the hardcover of $229. The rental is $75. I was able to get a five-year rental ebook for my course for $40, which was more reasonable, but you can only print two pages at a time, and the formatting is terrible. No color. Figures are disconnected from the reference text. Clearly they just took the hardcover version's word-processor document and uploaded it as an ebook with no thought to presentation, apparently as a punishment for renting the book instead of buying the most expensive version.
Quite an informative text for anyone wanting to aquire an in-depth knowledge of geographic information systems and its varying applications. I'm utilising it as an on-going reference.
