This book explains the concept of spatial data quality, a key theory for minimizing the risks of data misuse in a specific decision-making context. Drawing together chapters written by authors who are specialists in their particular field, it provides both the data producer and the data user perspectives on how to evaluate the quality of vector or raster data which are both produced and used. It also covers the key concepts in this field, such as: how to describe the quality of vector or raster data; how to enhance this quality; how to evaluate and document it, using methods such as metadata; how to communicate it to users; and how to relate it with the decision-making process. Also included is a Foreword written by Professor Michael F. Goodchild.

Rodolphe Devillers is Assistant Professor of Geography at the Memorial University of Newfoundland, Canada. He is also a member of the Center for Research in Geomatics (CRG) and the Canadian Network of Excellence GEOIDE. He has worked on different projects related to data quality in Europe (REVIGIS) and Canada (GEOIDE) and has published several articles related to data quality issues, mostly on the communication of spatial data quality information to end-users.
Robert Jeansoulin is Senior Researcher at the CNRS (Centre National de la Recherche Scientifique) in France, and works for the Center of Mathematics and Computer Sciences at the University of Provence. He has written several papers and books on the subject and has led the REVIGIS European Project; he is now co-chairing the ISPRS Technical Committee 2 on the Quality of Spatio-Temporal Data and Models.
