Beschreibung:
As Geographic Information Systems (GIS) have developed and their applications have been extended, the issue of uncertainty has become increasingly recognized. It is highlighted by the need to demystify the inherently complex geographical world to facilitate computerization in GIS, by the inaccuracies that emerge from man-machine interactions in data acquisition, and by error propagation in geoprocessing. Users need to be well aware of the likely impacts of uncertainties in spatial analysis and decision-making. This book discusses theoretical and practical aspects of spatial data processing and uncertainties, and covers a wide range of types of errors and fuzziness and emphasizes description and modeling. High level GIS professionals, researchers and graduate students will find this a constructive book.
Preface. Geographical Information and Uncertainty. Geographical Perspectives. Geographical Measurement and Data. Exploring Geographical Uncertainty. Uncertainty in Continuous Variables. Uncertainty in Categorical Variables. Uncertainty in Objects. Uncertainty-Informed Geographics. References. Index.
