Acknowledgments

We thank each other for making this book possible. If only one of us was writing this book, it would have been either a random stream of consciousness or an obsessively organized masterpiece that would never have been finished in our lifetime.

We thank our technical reviewer, Dr. Jan Hartmann, from the University of Amsterdam Department of Geography, who went above and beyond the call of duty in reviewing all chapters of our book, testing the code, and providing invaluable constructive criticism. We’d also like to thank Paul Ramsey for contributing the foreword and our illustrators Gary Battiston and Alejandro Gomez.

We thank everyone at Manning Publications. In particular, we acknowledge Marjan Bace and Karen Tegtmeyer for reviewing our proposal, organizing reviewer feedback, and giving us the opportunity to be published authors; our development editor, Sebastian Stirling, who endured many revisions of our chapters; and our production team of Linda Recktenwald, Mary Piergies, Barbara Mirecki, and others for keeping us focused during the production process.
