Building a GIS describes a time-tested approach to system architecture design specifically intended to ensure successful GIS operations. Over many years, author Dave Peters, Esri's Director of Systems Integration, has developed and fine-tuned platform sizing models to support the systems integration of the advanced and evolving technologies we see today. This system design methodology has already led to thousands of successful GIS deployments over the last two decades. Now with a state-of-the-art Capacity Planning Tool that embodies the methodology, anyone can try out various system configurations in theory before committing their resources. The book's reach is as broad as it is detailed, proving a valuable resource for IT experts just now adopting the technology, for GIS experts just now getting into system design, and for nontechnical executives who need to take advantage of advancements in technology while managing change.
