Uncertainty in Geographical Information pdf da Michael Goodchild
"Uncertainty in Geographical Information" by Michael Goodchild is a book that explores the concept of uncertainty in geographic information systems (GIS). The book provides an in-depth examination of the sources of uncertainty in GIS, the methods used to represent uncertainty, and the implications of uncertainty for decision-making.
The book begins with an overview of the importance of uncertainty in GIS and the different sources of uncertainty, including measurement error, modeling error, and data quality issues. Goodchild then explores the various methods used to represent uncertainty in GIS, including probabilistic methods, fuzzy logic, and rough sets. He also discusses the challenges of visualizing uncertainty and the importance of communicating uncertainty to decision-makers.
The book then delves into the practical implications of uncertainty in GIS, including the impact on spatial analysis, decision-making, and policy development. Goodchild emphasizes the importance of understanding uncertainty in these contexts and provides numerous examples of how uncertainty can affect the outcome of spatial analysis and decision-making processes.
Throughout the book, Goodchild emphasizes the need for a holistic approach to uncertainty in GIS that considers both the technical aspects of uncertainty representation and the practical implications for decision-making. He also highlights the importance of interdisciplinary collaboration and the need for GIS professionals to work closely with experts from other fields, such as statistics, decision science, and policy analysis.
Overall, "Uncertainty in Geographical Information" is a comprehensive and informative book that provides a thorough exploration of the concept of uncertainty in GIS. It is an essential read for anyone working in the field of GIS or spatial analysis and provides valuable insights into the challenges and opportunities of working with uncertain data.
