This second edition includes updated and substantially revised versions of chapters from the 2001 first edition, and new chapters on topics that have become prominent during the interval. Geographers working with information systems and information scientists working with geography explain some approaches and techniques for extracting knowledge from the data-rich environment that new electronic sensing and processing have created. Their topics include fundamentals of spatial data warehousing for geographic knowledge discovery, data quality issues, clustering methods in geographical data analysis, leveraging the power of spatial data mining to enhance the applicability of geographic information systems technology, multi-variate spatial clustering and geo-visualization, and periodic pattern discovery from trajectories of moving objects. Many of the high-quality monochrome illustrations embedded in the text are also reproduced in a battery of color plates. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
