Tile-Based Geospatial Information Systems (eBook, PDF)

Principles and Practices

• Format: PDF

Produktbeschreibung

Tile-based online mapping systems have replaced traditional Web GIS systems, because of their improved speed and usability. The trend towards tile-base systems was started by Internet services companies, such as Google, Yahoo, and Microsoft. They have been followed by the traditional GIS community, government organizations and open source development communities, because tile based systems yield faster and work stronger with 3-D mapping tools.

Tile-Based Geospatial Information Systems: Principles and Practices presents a detailed examination of the principles of tile-based systems. Topics include discussions of projections, coordinate systems, image processing, data basing and indexing requirements and web access. Attention is devoted to understanding and development of algorithms needed to make tile-based systems functional and efficient. In addition to the theoretical examination of the topic, this book includes detailed practical content helpful to those charged with implementation of tile-based systems. Case studies are provided in the last 2 chapters of this book.

Tile-Based Geospatial Information Systems: Principles and Practices is designed for a professional audience composed of researchers, practitioners and government workers, focusing on geographic information systems and internet technologies and image processing techniques related to GIS. This book is also suitable for advanced-level students in computer science and geography as a secondary text or reference book.

Autorenporträt

Dr. John T. Sample has worked for 12 years as a scientist in the Naval Research Laboratory's Geospatial Sciences and Technology branch. He has authored and edited articles, books, and book chapters on the topic of web based GIS. He currently has two patents granted related to web based GIS. He has developed a number of tile-based mapping systems in use by the Department of Defense and Department of Homeland Security. Dr. Sample received a Ph.D. in computer science from Louisiana State University in 2003 and a B.S. in mathematics from the University of Southern Mississippi in 1999.

Elias Z. K. Ioup is a Computer Scientist with the Naval Research Laboratory working on several geospatial research programs. He is the principal investigator for the GHUB Distributed Geospatial Repository program and a lead developer on the Geospatial Information Database (GIDB). These programs represent leading DoD efforts to leverage geospatial capabilities using Service Oriented Architectures and Web services. Elias Ioup received a Master's degree in Computer Science from the University of New Orleans in 2006 and Bachelor's degrees in Mathematics and Computer Science from the University of Chicago in 2003. He is currently a Ph.D. candidate in Engineering and Applied Science at the University of New Orleans.

Rezensionen

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)
