This hands-on guide offers in-depth, up-to-date material on issues of spatial data when designing and implementing enterprise GIS, along with insightful, illustrative examples. From the predesign planning stages dealing with assessment, requirement analysis, organizational issues, and cost analysis, to integrating legacy MIS systems and preparing for future developments in database design, this user-friendly book addresses all the fundamental aspects of the design and implementation of GIS, regardless of soltware or hardware. It offers helpful "decision trees" to assist in strategic planning, as well as proven strategies for application development, interface design, and enabling Web-bases access. Numerous case studies and examples from the private and public sectors demonstrate how these strategies and approaches play out in the real world.
