Thinking About GIS: Geographic Information System Planning for Managers presents a planning model for designing data and technology systems that will meet any organization's specific needs. Designed for two primary audiences--senior managers who oversee information technologies and technical specialists responsible for system design--this book provides a common platform on which to conduct GIS planning. The fourth edition reflects the latest trends in geospatial technology, and includes new case studies, exercises from author Roger Tomlinson's course Planning for a GIS, and video of his Planning and Managing a GIS seminar from the Esri International User Conference.
