The Accuracy of Spatial Databases

by Michael F. Goodchild (Editor), Sucharita Gopal (Editor)

This is a selection of the major papers from a meeting on database accuracy which took place in December 1988 in Montecito, USA. They look at errors and accuracy in spatial databases, particularly the problems of modelling uncertainties and reliability, testing accuracy and practical implications.; The chapters of the book represent a number of different perspectives on the accuracy problem, from efforts to simulate and model error to techniques for accommodating to it. The 23 chapters are organized into seven sections, and to provide a brief introduction to each.; The first and last sections are general overviews. In between, the papers in Section Two through Four look at error in GIS with increasing technical complexity and generality. Section Five groups together four papers on various aspects of error in the spatial analysis of socio-economic data, and Section Six contains four papers on more fundamental approaches to the particular problems of aggreation and reporting zone effects which underlie much modeling in human geography and related disciplines.
