Michael Goodchild est un géographe et un pionnier dans le domaine de la science de l'information géographique (SIG). Il est né le 24 février 1944 à Surrey, en Angleterre, et a obtenu son doctorat en géographie à l'Université de Bristol en 1969.

Goodchild est connu pour ses recherches sur les SIG, l'analyse spatiale et la télédétection. Il est l'auteur ou le co-auteur de plus de 15 livres et de plus de 500 articles, et a reçu de nombreux prix pour ses contributions dans le domaine de la géographie et des SIG.

En plus de son travail universitaire, Goodchild a été impliqué dans diverses organisations et initiatives liées au SIG, notamment en tant que rédacteur en chef de la revue "Geographical Analysis" et en tant que président fondateur du National Center for Geographic Information and Analysis (NCGIA) en les États Unis.

Goodchild est actuellement professeur émérite de géographie à l'Université de Californie à Santa Barbara et continue d'être actif dans la recherche et l'enseignement.

The Accuracy Of Spatial Databases pdf par Michael Goodchild

"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.
