[Termes IGN] système d'information géographiqueRésumé : (Editeur) GIS users and professionals are aware that the accuracy of GIS results cannot be naively based on the quality of the graphical output. Data stored in a GIS will have been collected or measured, classified, generalised, interpreted or estimated, and in all cases this allows the introduction of errors. With the processing or translation of this data into the GIS itself further propagation or amplification of errors also occur. It is essential that GIS professionals understand these issues systematically if they have to build ever more accurate systems. In this book the author's decade of study into these problems is brought into focus with an authoritative account of the development, application and implementation of error propagation techniques for use in environmental modelling with GIS. Its purpose is to provide a methodology for handling error and error propagation, for which the author is already well-respected internationally. The book is set to immediately become the classic reference source in its field and will be an essential read for GIS and environmental modelling professionals at both the practitioner and research levels.

[Termes IGN] Time-geographyRésumé : (Editeur) This book explores the major components of the object-oriented analysis and design methods, how they can be used for modelling spatio-temporal data, and how these components are developed and maintained within GIS. It also offers practical guidance to object-oriented methods by demonstrating the feasibility of applying such a method to issues involved in handling spatio-temporal data. The author demonstrates how this knowledge might be used in a wide range of applications such as political boundary record maintenance (historical data), disease incidence rate analysis in epidemics (diffusion data), and environmental studies of climate change (time-series data). This understanding contributes to the development of theory in GIS and improves the design of GIS to support the modelling of semantics, space, and time elements of geographical information.
