Zusatztext Wenzhong Shi's primary innovation is the integration of positional uncertainty and attribute uncertainty for both data and analysis. He presents case studies using common GIS techniques to demonstrate approaches that describe positional uncertainties in data and also to show how they would affect the results of analysis. His book is a well-organized text! emphasizing the recent literature on positional uncertainty. ... [The book] provides a template for the incorporation of spatial and attribute uncertainty in spatial analysis! and the template could be expanded to techniques more commonly employed by regional scientists. ... This text is an important reference for someone embarking on a research effort in spatial data uncertainty and modeling ...-Eun-Hye Enki Yoo and Jared Aldstadt! Department of Geography!

No. 4! 2011 Informationen zum Autor Wenzhong Shi Klappentext Modeling uncertainties in geographic information science is essential to the development of the field. This book addresses one of the fundamental theoretical issues: uncertainties in spatial data and analysis. Along with the latest research findings, the text provides methods to control uncertainties in GIS applications. The author contributes his own unique research in modeling positional uncertainty based on probability theory and statistics. New areas, such as uncertainty-based spatial mining, are introduced providing a new prospective on the theory and applications of GIS. Researchers, students, and professionals working in GIS can benefit from the insightful presentation of new ideas.
