This book is an immense collection of research on the application of complex systems to urban spatial analysis. While this book is not extensive and is probably not meant as a textbook on complex systems in its entirety, I highly recommend it for those interested in urban spatial analysis. The applications of the techniques go beyond geography and are useful in sociology, economics, or urban planning. A caveat that I should add is that the book is quite dense with methods and formulas and is probably not best to approach this book without some knowledge of advanced statistics. However, the theoretical overviews provided more than allow for those without this background to get something out of it. In short, if you are a graduate student, professor, or researcher I'd recommend this book for an insightful and important take on the nature of cities and urban analysis.
