About the Author

Wenzhong Shi


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 ...
