If we are to solve many of the problems facing us-in the cities, in the wild areas of the earth, in the atmosphere, and the oceans-we shall need the help of skilled users of GIS technology. If readers can master what is in this volume, they will be well started on this enterprise. -From the Foreword by Jack Dangermond President of ESRI Praise for previous editions: One of only a small number of texts devoted to the technology of GIS that are truly introductory in nature...Very readable and of moderate length. Those who are real novices to GIS will find this one attractive. -Computers and Geosciences Well-rendered and very clear line drawings ...well written, with a well-balanced blend of technical/theoretical concepts and more applied facts of GIS. -Professional Geographer Geographic Information Systems provides a practical, theory-driven overview of GIS that is supported with clear coverage of basic techniques. This treatment enables readers to understand the broad aspects of GIS without focusing on a specific software or discipline, such as engineering or geography. New features of this Third Edition include: up-to-date information on standardization efforts aimed at facilitating the exchange of ideas and data; technical content that is up to date with current hardware, software, database design, and analytical techniques; and comprehensive cost/benefit guidelines for choosing and evaluating a GIS, including coverage of organizational and technical issues.
