Essentials of Geographic Information Systems

Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential G.I.S. users are nonspecialists or may only need a few maps, this book is designed to be accessible, pragmatic, and concise. Essentials of Geographic Information Systems also illustrates how G.I.S. is used to ask questions, inform choices and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping, and G.I.S. In today’s world, learning involves knowing how and where to search for information. In some respects, knowing where to look for answers and information is arguably just as important as the knowledge itself. Because Essentials of Geographic Information Systems is concise, focused and directed, readers are encouraged to search for supplementary information and to follow up on specific topics of interest on their own when necessary. Essentials of Geographic Information Systems provides the foundations for learning G.I.S., but readers are encouraged to construct their own individual frameworks of G.I.S. knowledge. The benefits of this approach are two-fold. First, it promotes active learning through research. Second, it facilitates flexible and selective learning—that is, what is learned is a function of individual needs and interest. Since G.I.S. and related geospatial and navigation technology change so rapidly, a flexible and dynamic text is necessary in order to stay current and relevant. Though essential concepts in G.I.S. tend to remain constant, the situations, applications, and examples of G.I.S. are fluid and dynamic. Though this book is intended for use in introductory G.I.S. courses, Essentials of Geographic Information Systems will also appeal to the large number of certificate, professional, extension and online programs in G.I.S. that are available today. In addition to providing readers with the tools necessary to carry out spatial analyses, Essentials of Geographic Information Systems outlines valuable cartographic guidelines for maximizing the visual impact of your maps. The book also describes effective G.I.S. project management solutions that commonly arise in the modern workplace.
