Annotation c. Book News, Inc., Portland, OR (booknews.com)
Uses case studies to examine the various applications of each type of geographic information.
* Considers geographic information as a technical problem, an empowering application, a pure science endeavor, an academic pursuit and a social necessity.
* Provides a wide range of examples and applications to help readers understand technical discussions.
This exploration of geographic information and geographic information systems (GIS) expands the discussion beyond the normal input-processing-output sequence. It begins by examining the manipulations that support analytical uses of GIS, including measurement and frameworks, representations, data quality, transformation and operations, parametric mapping, simple logic and overlay, taxonomy, distance transformations and surfaces. It then moves on to discuss operations that connect the practical exercises in the book to professional applications of GIS techniques in bureaucratic, social and cultural contexts.
Includes bibliographical references (p. 273-282) and index.
