About this book
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.

Reviews
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. Malyankar, ACM Computing Reviews, September, 2011)Authors and Affiliations
