Tile-based mapping systems have grown to become the dominant form of mapping system with the rise of Web-based mapping tools. The origin of this book is a desire to collect all our discoveries, techniques, and best practices for creating a til- mapping system into one combined volume. The intent of this text is to provide a comprehensive guide to the theory behind creating a tiled-map system as well as a practical guide to create a concrete implementation.

From the reviews: "This book will be of interest primarily to practitioners: developers and designers of software systems that need map or imagery graphics. ... The material is clearly presented and easy to understand, and includes pointers to how different commercial and open-source systems or technologies available today ... . All in all, this book is a decent introduction to problems and solution techniques in the limited domain of tile-based services for geospatial information." (R. M.
