Although GIS provides powerful functionality for spatial analysis, data overlay and storage, these spatially oriented systems lack the ability to represent temporal dynamics, which is a major impediment to its use in surface modeling. However, rapid development of computing technology in recent years has made real-time spatial analysis and real-time data visualization become realizable. Based on newly developed methods, Surface Modeling: High Accuracy and High Speed Methods explores solutions to big-error and slow-efficiency problems, two critical challenges that have long plagued those working in with geographical information system (GIS) and computer-aided design (CAD). By developing high accuracy and high speed methods for surface modeling, the book builds a bridge between the mathematical-oriented theory of surface modeling and the user-oriented application where the user is actually able to retrieve information on the method itself. The author examines a novel method of high accuracy surface modeling (HASM) in terms of the fundamental theorem of surfaces. He then analyzes the coefficient matrix and develops an adaptive method of HASM (HASM-AM), a multi-grade method of HASM (HASM-MG), and an adjustment method of HASM (HASM-AD). He uses numerical tests and real world studies to demonstrate that HASM-AM, HASM-MG, and HASM-AD have highly accelerated computational speed, especially for simulations with huge computational work. Building on this, the book discusses a HASM-based method for dynamic simulation (HASM-FDS), and then applies HASM methods to simulate terrains, climate change, ecosystem change, land cover, and soil properties. It demonstrates HASM's potential for simulating population distribution, human carrying capacity, ecosystem services, ecological diversity, change detection, and wind velocity. The book concludes with a discussion of the problems that exist in surface modeling on a global level and evaluates possible solutions to these problems.

A revision of Openshaw and Abrahart's seminal work, GeoComputation, Second Edition retains influences of its originators while also providing updated, state-of-the-art information on changes in the computational environment. In keeping with the field's development, this new edition takes a broader view and provides comprehensive coverage across the field of GeoComputation. See What's New in the Second Edition: Coverage of ubiquitous computing, the GeoWeb, reproducible research, open access, and agent-based modelling Expanded chapter on Genetic Programming and a separate chapter developed on Evolutionary Algorithms Ten chapters updated by the same or new authors and eight new chapters added to reflect state of the art Each chapter is a stand-alone entity that covers a particular topic. You can simply dip in and out or read it from cover to cover. The opening chapter by Stan Openshaw has been preserved, with only a limited number of minor essential modifications having been enacted. This is not just a matter of respect. Openshaw's work is eloquent, prophetic, and his overall message remains largely unchanged. In contrast to other books on this subject, GeoComputation: Second Edition supplies a state-of-the-art review of all major areas in GeoComputation with chapters written especially for this book by invited specialists. This approach helps develop and expand a computational culture, one that can exploit the ever-increasing richness of modern geographical and geospatial datasets. It also supplies an instructional guide to be kept within easy reach for regular access and when need arises.

Have you ever really considered how much effect information technology has on society throughout the world? Sadly, progress often places lower income and marginalised communities at a distinct disadvantage. This book however, offers a detailed look at numerous incidences around the world where communities have actually taken control of the technology and really used it to their advantage. This is presented in the form of case studies and models which reflect on public participation in GIS concepts, best practices, constraints and opportunities.

This title was first published in 2003. With the increasing use of GIS in industrialised and developing countries, the availability of spatial data has become an issue that affects many public and private sector organisations. They are faced with the high cost and substantial effort involved in the generation of spatial data and so the sharing of this data is increasingly being seen as a way of overcoming expense and easing availability and access. But this can provide a way of using GIS effectively only if the key players involved in the use and supply of spatial data are willing to share. This book employs a theory from social psychology as an organising framework to systematize the determinants of organisations' spatial data sharing behaviour. It develops a model which explains the likely willingness of key individuals within organisations to engage in spatial data exchanges across organisational boundaries and then tests this on a survey based in South Africa.

Making space for imagination can shift research and community planning from a reflective stance to a "future forming" orientation and practice. Cultural mapping is an emerging discourse of collaborative, community-based inquiry and advocacy. This book looks at artistic approaches to cultural mapping, focusing on imaginative cartography. It emphasizes the importance of creative process that engages with the "felt sense" of community experiences, an element often missing from conventional mapping practices. International artistic contributions in this book reveal the creative research practices and languages of artists, a prerequisite to understanding the multi-modal interface of cultural mapping. The book examines how contemporary artistic approaches can challenge conventional asset mapping by animating and honouring the local, giving voice and definition to the vernacular, or recognizing the notion of place as inhabited by story and history. It explores the processes of seeing and listening and the importance of the aesthetic as a key component of community self-expression and self-representation. Innovative contributions in this book champion inclusion and experimentation, expose unacknowledged power relations, and catalyze identity formation, through multiple modes of artistic representation and performance. It will be a valuable resource for individuals involved with creative research methods, performance, and cultural mapping as well as social and urban planning.

This work reflects preoccupations with the threats posed to our environment due to climatic factors, major and natural hazards of all kinds and demographic influences. Topics covered include land surface processes, coastal zones and atmospheric risks.

Earth observation data policy has received little attention, even though the conditions of access to Earth observation data are fundamental to the exploitation of and the further growth of the Earth observation sector. This unique book addresses this limitation.

Maps have always been a fundamental tool in archaeological practice, and their prominence and variety have increased along with a growing range of digital technologies used to collect, visualise, query and analyse spatial data. However, unlike in other disciplines, the development of archaeological cartographical critique has been surprisingly slow; a missed opportunity given that archaeology, with its vast and multifaceted experience with space and maps, can significantly contribute to the field of critical mapping. Re-mapping Archaeology thinks through cartographic challenges in archaeology and critiques the existing mapping traditions used in the social sciences and humanities, especially since the 1990s. It provides a unique archaeological perspective on cartographic theory and innovatively pulls together a wide range of mapping practices applicable to archaeology and other disciplines. This volume will be suitable for undergraduate and postgraduate students, as well as for established researchers in archaeology, geography, anthropology, history, landscape studies, ethnology and sociology.

A balanced review of differing approaches based on remote sensing tools and methods to assess and monitor biodiversity, carbon and water cycles, and the energy balance of terrestrial ecosystem. Earth Observation of Ecosystem Services highlights the advantages Earth observation technologies offer for quantifying and monitoring multiple ecosystem functions and services. It provides a multidisciplinary reference that expressly covers the use of remote sensing for quantifying and monitoring multiple ecosystem services. Rather than exhaustively cover all possible ecosystem services, this book takes a global look at the most relevant remote sensing approaches to estimate key ecosystem services from satellite data. Structured in four main sections, it covers carbon cycle, biodiversity, water cycle, and energy balance. Each section contains a review of conceptual and empirical methods, techniques, and case studies linking remotely sensed data to the biophysical variables and ecosystem functions associated with key ecosystem services. The book identifies relevant issues and challenges of assessment, presents cutting-edge sensing techniques, uses globally implemented tools to quantify ecosystem functions, and presents examples of successful monitoring programs. Covering recent developments undertaken on the global and national stage from Earth observation satellite data, it includes valuable lessons and recommendations and novel ways to improve current global monitoring systems. The book delineates the use of Earth observation data so that it can be used to quantify, map, value, and manage the valuable goods and services that ecosystems provide to societies around the world.

The ideas and techniques of virtual reality are now being made available for the creation of artificial or virtual geographies (a virtual geography refers to the creation of artificial geographies for use in research and teaching, using ideas and techniques from the field of virtual reality (VR)).
Such virtual geographies are currently being constructed and used at a number of sites and include virtual cities, landscape visualisation, visualising past and future geographies, visualising abstract concepts and taking people on virtual field courses.
Virtual Reality in Geography covers 'through the window' VR systems, 'fully immersive' VR systems and hybrids of the two types. The authors examine the Virtual Reality Modelling Language approach, and explore its deficiencies when applied to real geographic environments. This book will be of great interest to geographers, computer scientists and all those interested in multimedia and computer graphics. There is an accompanying CD-ROM containing a rich selection of images and pieces of virtual reality software.
This is a totally unique book covering an area of geography that is rapidly becoming used in all aspects of the field. It covers all the major uses and methods of virtual reality used by geographers and the lack of anything else written about the subject to date should ensure a wide readership. The authors have produced a CDROM that comes with the book of virtual reality images that will be a fascinating companion to the text.

The text develops the principal aspects of applied Fourier analysis and methodology with the main goal to inculcate a different way of perceiving global and regional geodetic and geophysical data, namely from the perspective of the frequency, or spectral, domain rather than the spatial domain. The word "methods" in the title is meant to convey that the transformation of a geophysical signal into the spectral domain can be applied for purposes of analysis as well as rapid computation. The text is written for graduate students; however, Chapters 1 through 4 and parts of 5 can also benefit undergraduates who have a solid and fluent knowledge of integral and differential calculus, have some statistical background, and are not uncomfortable with complex numbers. Concepts are developed by starting from the one-dimensional domain and working up to the spherical domain, which is part of every chapter. Many concepts are illustrated graphically with actual geophysical data primarily from signals of gravity, magnetism, and topography.

There is considerable current academic interest in the interface between geographical information systems (GIS) and the environment. This new monograph explores the process from start to finish. It begins with information acquisition in the environment and moves on to tool and techniques for manipulating the information, visualisation and navigation methods for exploring it, and computation and modelling techniques for its analysis. It then concludes with a survey of decision support, for its application.
Spatial Information and the Environment is the eighth book in the Innovations in GIS series initiated in 1994. The series is in essence derived from a selection of the presentations made at the annual GIS Research UK conference 2000 held in York, and has now changed its focus by concentrating on a single topic, making each text distinctive.

The intensive use of limited water resources, the growing population rates and the various increasing human activities put high and continuous stresses on these resources. Major problems affecting the water quality of rivers, streams and lakes may arise from inadequately treated sewage, poor land use practices, inadequate controls on the discharges of industrial waste waters, uncontrolled poor agricultural practices, excessive use of fertilizers, and a lack of integrated watershed management. This study explores the impact of these pollution problems and the water quality degradation of irrigated agricultural watersheds. When the watersheds have a complex physical basis of interacting water bodies such as canals, drains and coastal lagoons as in the case of irrigated watersheds in coastal river Deltas, and when these environments are 'data scarce environments', the problems of managing water quality becomes more obvious and the need for reliable solutions becomes an urgent requirement.

The third international workshop on applications of computational mechanics in geotechnical engineering discussed the area of computational mechanics applied to geotechnical problems. During the event, topics such as ground reinforcement and computational models were covered.

Information shapes urban spaces in ways that most people rarely stop to consider. From data-driven planning to grassroots activism to influencing the routes we walk, bike, and drive, new information technologies are helping city dwellers to leverage information in new ways. These technologies shape the uses and character of urban spaces. Information technologies and tools such as social media and GIS tracking applications are being used by individuals as they go about their daily lives, not as alternatives to social interaction, but as opportunities to participate in the shared experience of urban life. This edited volume focuses on the creative application and management of information technologies in urban environments, with an emphasis on the intersection between citizen participation in creating city environments and the policy-making that supports it. The chapters address critical issues including the digital divide, transportation planning, use of public spaces, community building, and local events. This book was originally published as a special issue of the Journal of Urban Technology.

The intersection of two disciplines and technologies which have become mature academic research topics in the 1990s was destined to be a dynamic area for collaboration and publication. However, until now no significant book-length treatment of the meeting of GIS and Virtual Reality has been available. This volume puts that situation to rights by bringing these together to cement some common understanding and principles in a potentially highly promising area for technological collaboration and cross-fertilisation.
The result is a volume which ranges in subject matter from studies of a Virtual GIS Room to Spatial Agents, and from an Environmental Multimedia System to Computer-Assisted 3D Geographic Education. All the contributors are well-known international scientists, principally from the computational side of GIS. It will be a valuable resource for any GIS researcher or professional looking to understand the leading edge of this fertile field.

Taking a detailed, non mathematical approach to two broad areas of principles and applications, this book progresses from the physical principles on which remote sensing is based - equipment, techniques and data analysis -through to the application of remote sensing to both physical phenomena and events, and to human activies and man-made landscapes.

GeoMeasurements by Pulsing TDR Cables and Probes examines Time Domain Reflectometry (TDR) research and provides information on its use as a robust, reliable, and economical production tool.
Common uses for TDR technology include telecommunications and power industries, but the text examines applications such as measurement of moisture of unsaturated soils; detection of fluids for leak and pollution; measurement of water levels for hydrological purposes; measurement of water pressures beneath dams; and deformation and stability monitoring of mines, slopes, and structures.
Chapters discuss:
· basic physics of signal generation, transmission, and attenuation along the coaxial cable
· probe designs and procedures for calibration as well as the variation in probe responses to changes in water content and soil mineralogy
· variations in waveform characteristics associated with cable, deformation, cable calibration, and installation techniques for metallic cables in rock
· several cases demonstrating the use of TDR cables in soil as well as weathered and soft rock
· a rationale for the use of compliant cable in soil
· the use of metallic cable (MTDR) and optical fiber (OTDR) to monitor response of structures
· sensor/transducer components, connections from the sensors to the TDR pulser/sampler, and system control methods
· available software for transmission and analysis of TDR signatures
The diverse interest and terminology within the TDR community tends to obscure commonalities and the universal physical principles underlying the technology. The authors seek to crystallize the basic principles among the seemingly divergent specialties using TDR technology in geomaterials. By examining varied experiences, GeoMeasurements by Pulsing TDR Cables and Probes provides a synergistic text necessary to unify the field.
