The Accuracy Of Spatial Databases
Taylor & Francis Ltd (Verlag)
978-0-85066-847-6 (ISBN)
The book addresses the problem of accuracy of spatial databases, and comprises of papers drawn from a wide range of physical and human systems, taking approaches which vary from statistical to descriptive. Together they present both a comprehensive review of existing knowledge, techniques and experience, and an analysis of critical research needs in this area of spatial data handling.
