The Accuracy Of Spatial Databases pdf 迈克尔·古德柴尔德
"The Accuracy of Spatial Databases" by Michael Goodchild is a comprehensive exploration of the fundamental issues surrounding the accuracy of spatial data. The book presents a detailed analysis of the factors that contribute to errors in spatial databases and provides practical strategies for improving accuracy.
The book begins with an overview of the concept of accuracy and the different types of errors that can occur in spatial databases. Goodchild then delves into the various sources of error in spatial data, including positional accuracy, attribute accuracy, and logical consistency.
The next section of the book focuses on methods for assessing and measuring accuracy in spatial databases. Goodchild presents a range of techniques for assessing accuracy, from traditional statistical methods to newer methods based on machine learning and data mining.
The book then goes on to discuss strategies for improving the accuracy of spatial databases. Goodchild emphasizes the importance of data quality control and provides practical guidance on how to identify and correct errors in spatial data. He also explores the use of spatial data standards and the importance of metadata in ensuring the accuracy of spatial databases.
The final section of the book discusses the broader implications of spatial database accuracy, including its impact on decision-making, environmental management, and social justice. Goodchild argues that accurate spatial databases are essential for addressing a wide range of social, economic, and environmental challenges, and that efforts to improve accuracy must be driven by a commitment to social responsibility and ethical practice.
Overall, "The Accuracy of Spatial Databases" is an essential resource for anyone working with spatial data, from GIS professionals to researchers and policymakers. Its comprehensive analysis of the factors contributing to errors in spatial databases and practical strategies for improving accuracy make it a valuable reference for anyone seeking to ensure the quality and reliability of spatial data.
