Oliver O’Brien reviews OpenStreetMap: Using and Enhancing the Free Map of the World by Frederik Ramm, Jochen Topf and Steve Chilton. “The book succeeds in simultaneously being OpenStreetMap for Dummies, OpenStreetMap: The Missing Manual and the O’Reilly OpenStreetMap book — that is to say, complete beginners, intermediate users and enthusiasts/hackers will all get something out of the book. If you are at all interested in the OpenStreetMap project, even if you don’t intend to contribute to the project but are just curious about what it is or what you can do with it, then I recommend this book. It’s as near-perfect as any book can be about one of the web’s, and the geospatial community’s, most exciting projects.”
