The book presents new clustering schemes, dynamical systems and pattern recognition algorithms in geophysical, geodynamical and natural hazard applications. The original mathematical technique is based on both classical and fuzzy sets models. Geophysical and natural hazard applications are mostly original. However, the artificial intelligence technique described in the book can be applied far beyond the limits of Earth science applications. The book is intended for research scientists, tutors, graduate students, scientists in geophysics and engineers

Other areas described are basic dynamics, data analysis techniques, numerical modelling, and remote sensing.

This book is primarily aimed at graduate and senior undergraduate courses in the area of ocean-atmosphere research.

Spatio-Temporal Databases explores recent trends in flexible querying and reasoning about time- and space-related information in databases. It shows how flexible querying enhances standard querying expressiveness in many different ways, with the aim of facilitating extraction of relevant data and information. Flexible spatial and temporal reasoning denotes qualitative reasoning about dynamic changes in the spatial domain, characterized by imprecision or uncertainty (or both). Many of the contributions focus on GIS, while some others are more general, or focus on related application fields, presenting theoretical viewpoints and techniques that are inspiring or can be adapted for GIS. The first part bundles the contributions on advances at the theoretical level, also discussing examples and opening further perspectives. The second part presents contributions on well-developed applications. The authors explain how to handle imprecision and uncertainty, demonstrating how advanced techniques can help to solve diverse problems related to GIS.

Environmental information systems (EIS) are concerned with the management of data about the soil, the water, the air, and the species in the world around us. This first textbook on the topic gives a conceptual framework for EIS by structuring the data flow into 4 phases: data capture, storage, analysis, and metadata management. This flow corresponds to a complex aggregation process gradually transforming the incoming raw data into concise documents suitable for high-level decision support. All relevant concepts are covered, including statistical classification, data fusion, uncertainty management, knowledge based systems, GIS, spatial databases, multidimensional access methods, object-oriented databases, simulation models, and Internet-based information management. Several case studies present EIS in practice.

World-renowned experts in spatial statistics and spatial econometrics present the latest advances in specification and estimation of spatial econometric models. This includes information on the development of tools and software, and various applications. The text introduces new tests and estimators for spatial regression models, including discrete choice and simultaneous equation models. The performance of techniques is demonstrated through simulation results and a wide array of applications related to economic growth, international trade, knowledge externalities, population-employment dynamics, urban crime, land use, and environmental issues. An exciting new text for academics with a theoretical interest in spatial statistics and econometrics, and for practitioners looking for modern and up-to-date techniques.

This book presents a selection of innovative ideas currently shaping the development and testing of geographical systems models by means of statistical and computational approaches. It spans all geographic scales, deals with both individuals and aggregates, and represents natural, human, and integrated spatial systems. This book is relevant to researchers, (post and under)graduates, and professionals in the areas of quantitative geography, spatial analysis, spatial modelling, and geographical information sciences.

The emphasis now placed on the concept of sediment cells as boundaries for coastal defence groups, and the development of SMPs, should help CPAs realise the importance of natural processes at the coast when designing defence and protection schemes. However, this will only be the case where defence groups exist, and where CPAs take up the challenge of developing SMPs. Coastal landscapes have been produced by the natural forces of wind, waves and tides, and many are nationally or internationally important for their habitats and natural features. Past practices at the coast, such as the construction of harbours, jetties and traditional defence systems may have contributed to the deterioration of the coast. English Nature (1992) have argued that if practices and methods of coastal defence are allowed to continue, then coastlines would be faced with worsening consequences, including: The loss of mudflats and the birds which live on them Damage to geological Sites of Special Scientific Interest (SSSIs) and scenic heritage by erosion, due to the stabilisation of the coast elsewhere Cutting of sediment supplies to beaches resulting in the loss of coastal wildlife Cessation through isolation from coastal processes, of the natural operation of spits, with serious deterioration of rare plants, animals and geomorphological and scenic qualities (English Nature, 1992) A number of designations, provided by national and international legislation do exist to aid conservation.

Gaussian scale-space is one of the best understood multi-resolution techniques available to the computer vision and image analysis community. It is the purpose of this book to guide the reader through some of its main aspects. During an intensive weekend in May 1996 a workshop on Gaussian scale-space theory was held in Copenhagen, which was attended by many of the leading experts in the field. The bulk of this book originates from this workshop. Presently there exist only two books on the subject. In contrast to Lindeberg's monograph (Lindeberg, 1994e) this book collects contributions from several scale space researchers, whereas it complements the book edited by ter Haar Romeny (Haar Romeny, 1994) on non-linear techniques by focusing on linear diffusion. This book is divided into four parts. The reader not so familiar with scale-space will find it instructive to first consider some potential applications described in Part 1. Parts II and III both address fundamental aspects of scale-space. Whereas scale is treated as an essentially arbitrary constant in the former, the latter em phasizes the deep structure, i.e. the structure that is revealed by varying scale. Finally, Part IV is devoted to non-linear extensions, notably non-linear diffusion techniques and morphological scale-spaces, and their relation to the linear case. The Danish National Science Research Council is gratefully acknowledged for providing financial support for the workshop under grant no. 9502164."

It was in September 1906 that the predecessor of the IAG, the 'Internationale Erdmessung', th organized the 15 General Assembly at the Hungarian Academy of Sciences in Budapest. It was 95 years later, in September 2001, that the IAG returned to this beautiful city to hold its Scientific Assembly, IAG 2001, in the historical premises of the Academy. The meeting took place from September 2-7, 2001 and continued the tradition of Scientific Assemblies, started in Tokyo (1982) and continued in Edinburgh (1989), Beijing (1993) and Rio de Janeiro (1997). Held every four years at the midpoint between General Assemblies of the IAG, they focus on giving an integrated view of geodesy to a broad spectrum of researchers and practitioners in geodesy and geophysics. The convenient location of the main building of the Hungarian Academy in downtown Budapest and the superb efforts of the Local Organizing Committee contributed in a major way to the excellent atmosphere of the meeting. As at previous meetings, the scientific part of the program was organized as a series of symposia which, as a whole, gave a broad overview of actual geodetic research activities. To emphasize an integrated view of geodesy, the symposia did not follow the pattern of the IAG Sections, but focussed on current research topics to which several IAG Sections could contribute. Each symposium had 5 sessions with presented papers and poster sessions on two consecutive days.

Under leadership of CT de Wit a large amount of modeling, building prototypes and also application, was carried out in the 1970s and 1980s. Comprehensive models were built, evaluated and carefully documented in the areas of crop growth production, plant breeding, soil water and nutrients, and in crop protection. Simulation techniques and biophysical theories developed in parallel. Simulation and experimentation always went hand in hand. Much of this work is documented in a long series of PhD theses under supervision of De Wit, in the series of Simulation Monographs (PUDOC), and in numerous other publications. This work has inspired many scientists across the global science community. The CT de Wit Graduate School of Production Ecology (PE) of the Wageningen University builds further on this platform and finds new subjects for research on and with models, and data. The PE platform provides also an excellent opportunity to develop contacts, cooperation and joint software with research groups in related fields and abroad. This book precipitates from such an exploration in new directions. We realize that modem information systems and statistics can offer a substantial contribution to the modelling framework. Good examples can be found here, and these provide a clear direction for the years to come.

Terrain has a profound effect upon the strategy and tactics of any military engagement and has consequently played an important role in determining history. In addition, the landscapes of battle, and the geology which underlies them, has helped shape the cultural iconography of battle certainly within the 20th century. In the last few years this has become a fertile topic of scientific and historical exploration and has given rise to a number of conferences and books. The current volume stems from the international Terrain in Military History conference held in association with the Imperial War Museum, London and the Royal Engineers Museum, Chatham, at the University of Greenwich in January 2000. This conference brought together historians, geologists, military enthusiasts and terrain analysts from military, academic and amateur backgrounds with the aim of exploring the application of modem tools of landscape visualisation to understanding historical battlefields. This theme was the subject of a Leverhulme Trust grant (F/345/E) awarded to the University of Greenwich and administered by us in 1998, which aimed to use the tools of modem landscape visualisation in understanding the influence of terrain in the First World War. This volume forms part of the output from this grant and is part of our wider exploration of the role of terrain in military history. Many individuals contributed to the organisation of the original conference and to the production of this volume.

Scientific visualization may be defined as the transformation of numerical scientific data into informative graphical displays. The text introduces a nonverbal model to subdisciplines that until now has mostly employed mathematical or verbal-conceptual models. The focus is on how scientific visualization can help revolutionize the manner in which the tendencies for (dis)similar numerical values to cluster together in location on a map are explored and analyzed. In doing so, the concept known as spatial autocorrelation - which characterizes these tendencies - is further demystified.

The Real and Virtual Worlds of Spatial Planning brings together contributions from leaders in landscape, transportation, and urban planning. They present case studies - from North America, Europe, Australia, Asia and Africa - that ground the exploration of ideas in the realities of sustainable urban and regional planning, landscape planning and present the prospects for using virtual worlds for modeling spatial environments and their application in planning. The first part explores the challenges for planning in the real world that are caused by the dynamics of socio-spatial systems as well as by the contradictions of their evolutionary trends related to their spatial layout. The second part presents diverse concepts to model, analyze, visualize, monitor and control socio-spatial systems by using virtual worlds

In recent years 3D geo-information has become an important research area due to the increased complexity of tasks in many geo-scientific applications, such as sustainable urban planning and development, civil engineering, risk and disaster management and environmental monitoring. Moreover, a paradigm of cross-application merging and integrating of 3D data is observed. The problems and challenges facing today's 3D software, generally application-oriented, focus almost exclusively on 3D data transportability issues - the ability to use data originally developed in one modelling/visualisation system in other and vice versa. Tools for elaborated 3D analysis, simulation and prediction are either missing or, when available, dedicated to specific tasks. In order to respond to this increased demand, a new type of system has to be developed. A fully developed 3D geo-information system should be able to manage 3D geometry and topology, to integrate 3D geometry and thematic information, to analyze both spatial and topological relationships, and to present the data in a suitable form. In addition to the simple geometry types like point line and polygon, a large variety of parametric representations, freeform curves and surfaces or sweep shapes have to be supported. Approaches for seamless conversion between 3D raster and 3D vector representations should be available, they should allow analysis of a representation most suitable for a specific application.

This book provides a comprehensive summary of the recent developments in wind erosion research and a clear outline of its future directions. The physics of wind erosion, from particle entrainment to transport and deposition, is described with rigor from the viewpoints of fluid dynamics and soil physics. The techniques for quantitative wind- erosion prediction through computational modelling constitutes a unique feature of this book in contrast to others published in the same field. The author has advocated the development of integrated wind-erosion modelling systems which couple dynamic models for the atmosphere and land surface with spatially distributed data for land-surface conditions. The successful applications of such a system have demonstrated its usefulness in wind-erosion assessment and prediction on regional to continental scales.

This book offers a valuable reference point for researchers and postgraduate students engaged in wind-erosion related studies, ranging from global climate change to atmospheric aerosols, dust storms, air quality, and land conservation.

The second edition has been expanded and updated throughout. It includes new information regarding mineral dust, a major focal point of studies on climate change in recent years as well as lidar information. It features some simplified sections to be more readily accessible by readers.

Just as in the era of great achievements by scientists such as Newton and Gauss, the mathematical theory of geodesy is continuing the tradition of producing exciting theoretical results, but today the advances are due to the great technological push in the era of satellites for earth observations and large computers for calculations. Every four years a symposium on methodological matters documents this ongoing development in many related underlying areas such as estimation theory, stochastic modelling, inverse problems, and satellite-positioning global-reference systems. This book presents developments in geodesy and related sciences, including applied mathematics, among which are many new results of high intellectual value to help readers stay on top of the latest happenings in the field.

This volume is the result of an invited symposium titled "Integrated Land-Use and Environmental Models: A Survey of Current Applications and Research" that was held in October 2000 at Arizona State University. The idea for the symposium arose from a belief held by many academics that we are at the watershed of a new generation of models that are more dynamic, more pragmatic, more interdiscipli nary, and more amenable to collaborative decision making. Several academics and professionals engaged in urban research had long realized that domain-specific knowledge was inadequate for understanding and managing urban growth. While interdisciplinary approaches have become critical in most social research, one general area of knowledge that stands out as having the most wide-ranging impact on current urban modeling efforts is the field comprised of environmental sciences and ecology. The symposium offered a forum for academics and professionals engaged in urban and ecological modeling to exchange ideas and experiences, specifically in areas that overlapped urban and environmental issues. The contri butions to this volume highlight the progress made in the various efforts to build integrated urban and environmental models. More importantly, each chapter shows how ideas have diffused across disciplinary boundaries to create better policy-relevant models. In addition, this book outlines some promising areas of research that could make important contributions to the field of urban and envi ronmental modeling. Integrated thinking about urban and environmental issues has been fundamental to the concept of sustainability."

Based on an international symposium held in Tokyo, the volume combines papers in the fields of gravity, geoid and marine geodesy. Special emphasis is placed on the use of gravity in modeling tectonic processes and the problems of geophysical inversion. In addition, absolute and relative gravity measurement in static and airborne mode, satellite altimetry, geopotential modeling, and global geodynamics are dealt with. The field of marine geodesy includes contributions on sea level change, seafloor deformation and mapping, sea surface positioning, electronic charting, and datum transformations.

This 4th volume of LIGHT SCATTERING REVIEWS is devoted to modern knowledge and milestones in both experimental and theoretical techniques related to light scattering and radiative transport problems. It consists of 3 chapters comprising 12 contributions written by leading world experts in their respective fields. The general focus of the book is on single light scattering and radiative transfer. The three chapters are devoted to experimental studies in the optics of light scattering media.

The first chapter consists of three parts: In the first part, the main properties of scattering matrices are presented in a systematic way, together with polarimetric decomposition theorems in a great detail. The Green s function techniques for plane wave scattering by nonspherical particles is introduced in the second part. Different conceptual advantages and disadvantages of various numerical schemes developed in the past for the calculation of light scattering and absorption properties of small particles are discussed. The chapter concludes with studies of representations of the rotation group and T-matrix methods as applied for the calculation of optical properties of small particles with various habits.

The second chapter of the book describes recent results in the broad area of forward and inverse problems of the radiative transfer. The first paper surveys techniques for theoretical studies of light scattering and polarization of molecular atmosphere. The application of time-dependent radiative transfer equation for cloud remote sensing and the peculiarities of radiative transfer of fluorescent and bioluminescent light in biological tissues are then considered, together with the importance of optical imaging in clinical and pre-clinical applications. The applications of the linearized radiative transfer equation and inverse problems for a particular case of the spherical atmosphere are included.

The final chapter of the book covers recent advances in the experimental studies in the field of light scattering media optics. The instruments, measurements, and data processing used in experimental studies of optical properties of small particles using an imaging technique are extensively described before a study of aerosols in a controlled environment using static and dynamic light scattering. The book ends with a description of advances in dynamic light scattering techniques.

This fourth volume gives a valuable picture of recent developments in the areas of single light scattering, radiative transfer in particulate media (e.g., terrestrial atmosphere and tissues), and inverse problems for multiple scattering media. It will further facilitate studies in light scattering media optics and aid researchers across various scientific fields, including astronomy, meteorology, biophysics, medical optics and geophysics."

Effective utilization of satellite positioning, remote sensing, and GIS in disaster monitoring and management requires research and development in numerous areas, including data collection, information extraction and analysis, data standardization, organizational and legal aspects of sharing of remote sensing information. This book provides a solid overview of what is being developed in the risk prevention and disaster management sector.
