Archaeology has been transformed by technology that allows one to see below the surface of the earth. This work illustrates the uses of advanced technology in archaeological investigation. It deals with hand-held instruments that probe the subsurface of the earth to unveil layering and associated sites; underwater exploration and photography of submerged sites and artifacts; and the utilization of imaging from aircraft and spacecraft to reveal the regional setting of archaeological sites and to assist in cultural resource management.

Recognized and advocated as a powerful tool, the role of remote sensing in identifying, mapping, and monitoring soil salinity and salinization will continue to expand. Remote Sensing of Soil Salinization: Impact on Land Management delineates how to combine science and geospatial technologies for smart environmental management. Choose the Right Techniques for the Job An overview of soil salinity assessment using remote sensing technologies, the book describes a variety of sensors, ranging from ground-based to airborne and satellite-borne, and their use in a diversity of geographical regions and environmental settings from coastal to inland saline areas. It provides guidance on how to identify and choose the right remote sensing tools and data sets required based on the purpose of the study and the environmental setting. Organized into three sections, the book covers: Section I: Soil Salinity and Remote Sensing: The Object and the Tool - Focuses on the relationships between the landscape-object salinity and the remote sensing tools Section II: Trends in Mapping Soil Salinity and Monitoring Salinization Using Remote and Proximal Sensing - Provides a variety of case studies dealing with soil salinity mapping and monitoring the process of salinization Section III: Diversity of Approaches to Modeling Soil Salinity and Salinization - Demonstrates the diversity of approaches used in modeling soil salinity and salinization in space and time Combines Fundamentals, the Latest Technology, and Practical Examples The book includes analyses of basic issues of remote detection, such as the spectral behavior of salt types and vegetation influence, and evaluations of currently available remote sensing platforms delineating their advantages and disadvantages.

The first part of the proceedings describes the current capabilities of various satellite experiments which are performing measurements of the Earth's atmosphere, as for example some of the results obtained recently by three experiments onboard the ENVISAT Environment Satellite (ENVISAT), namely, the Global Ozone Monitoring Experiment (GOME), the SCanning Imaging Absorption for Atmospheric CHartographY (SCIAMACHY) and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). For the analysis of spectra recorded by these instruments it is necessary to make good use of efficient radiative transfer codes. These computer codes need as input, a dataset of high quality spectroscopic parameters which can be generated only through a careful analysis of high quality laboratory measurements. In addition some of the future satellite missions which are under preparation at the European Space Agency (ESA) are briefly described.

GNSS - GPS, GLONASS, Galileo and more is the extension of the scientific bestseller GPS - Theory and Practice to Global Navigation Satellite Systems (GNSS) and includes the Russian GLONASS, the European system Galileo, and additional systems.

The book refers to GNSS in the generic sense to describe the various existing reference systems for coordinates and time, the satellite orbits, the satellite signals, observables, mathematical models for positioning, data processing, and data transformation.

With respect to the individual systems GPS, GLONASS, Galileo and more, primarily the specific reference systems, services, the space and the control segment, as well as satellite signals are described. Furthermore, augmentations by space- and ground-based systems are discussed.

This book is a university-level introductory textbook and is intended to serve as a reference for students as well as for professionals and scientists in the fields of geodesy, surveying engineering, navigation, and related disciplines."

This introduction to the use of radar for remote sensing of natural surfaces provides the reader with a thorough grounding in practical applications, focusing particularly on terrestrial studies that may be extended to other planets. An historical overview of the subject is followed by an introduction to the nomenclature and methodology pertaining to radar data collection, image interpretation and surface roughness analysis. The author presents a summary (illustrated with examples from the natural environment) of theoretical explanations for the backscatter properties of continuous rough surfaces, collections of discrete objects, and layered terrain.

This volume contains the papers presented at the Conference on Spatial Inf- mationTheory, heldinEllicottville, NewYorkinSeptember 2005.COSIT2005 was the 7th International Conference held under the COSIT name. When - drewFrankandhiscolleaguesorganizedthe?rstCOSITconferenceontheisland of Elba, Italy, in 1993, it represented the maturing of an international research community that had already met four or ?ve times in the United States, Spain, and Italy. Of course, cognitive and computational approaches to space and s- tial phenomena werenot themselves new topics, but a contextof providingth- retical underpinning for geographicinformation systems refocused some of these researchers and brought them up against practical and conceptual challenges. A second international symposium under the COSIT name, held in Semmering, Austria in 1995, established COSIT as a biennial conference series that cont- ued at Laurel Highlands, Pennsylvania, USA (1997), Stade, Germany (1999), Morro Bay, California, USA (2001) and Ittingen, Switzerland (2003). A prod- tive partnership with Springer s Lecture Notes in Computer Science has ensured that the papers from every COSIT meeting have been widely disseminated, and the COSIT community has contributed signi?cantly to the development of G- graphic Information Science, Geoinformatics and Spatial Information Theory in general."

The applications of image-based measurement are many and various: image-guided surgery, mobile-robot navigation, component alignment, part inspection and photogrammetry, among others. In all these applications, landmarks are detected and located in images, and measurements made from those locations.Precision Landmark Location for Machine Vision and Photogrammetry addresses the ubiquitous problem of measurement error associated with determining the location of landmarks in images. With a detailed model of the image formation process and landmark location estimation, the Cramer-Rao Lower Bound (CRLB) theory of statistics is applied to determine the least possible measurement uncertainty in a given situation.This monograph provides the reader with: the most complete treatment to date of precision landmark location and the engineering aspects of image capture and processing; detailed theoretical treatment of the CRLB; a software tool for analyzing the potential performance-specific camera/lens/algorithm configurations; two novel algorithms which achieve precision very close to the CRLB; an experimental method for determining the accuracy of landmark location; and, downloadable MATLAB registered] package to assist the reader with applying theoretically-derived results to practical engineering configurations. All of this adds up to a treatment that is at once theoretically sound and eminently practical.Precision Landmark Location for Machine Vision and Photogrammetry will be of great interest to computer scientists and engineers working with and/or studying image processing and measurement. It includes cutting-edge theoretical developments and practical tools so it will appeal to research investigators and system designers.

A critical issue which is fundamentally affecting the development of the Earth Observation sector is not so much the technology but the data policy. The conditions which govern access to the data, distribution of the data and the price of the data are now vital to the exploitation of this important environmental data resource. This book examines and analyses these data policy issues and recommends how the Earth observation sector can best develop appropriate and useful policies so that the scientific, operational and commercial value of the data can be maximised. This book provides a summary of the influences on Earth observation data policy and a review of the main organisations which develop Earth observation data policy including the United States, the committee on Earth Observation Satellites, the International Earth Observing System and space agencies such as the European Space Agency. The book analyses four key parts to Earth observation data policy: access to Earth observation data, data protection, pricing policy and data preservation. Details of the satellite Earth observation systems of the United States, Europe, Japan, Canada and other nations are included throughout the book. In preparing the book the author has interviewed over 70 experts in Earth observation data policy in Europe, the United States and Canada.

GIS is used today to better understand and solve urban problems. GIS in Sustainable Urban Planning and Management: A Global Perspective, explores and illustrates the capacity that geo-information and GIS have to inform practitioners and other participants in the processes of the planning and management of urban regions. The first part of the book addresses the concept of sustainable urban development, its different frameworks, the many ways of measuring sustainability, and its value in the urban policy arena. The second part discusses how urban planning can shape our cities, examines various spatial configurations of cities, the spread of activities, and the demands placed on different functions to achieve strategic objective. It further focuses on the recognition that urban dwellers are increasingly under threat from natural hazards and climate change. Written by authors with expertise on the applications of geo-information in urban management, this book showcases the importance of GIS in better understanding current urban challenges and provides new insights on how to apply GIS in urban planning. It illustrates through real world cases the use of GIS in analyzing and evaluating the position of disadvantaged groups and areas in cities and provides clear examples of applied GIS in urban sustainability and urban resilience. The idea of sustainable development is still very much central in the new development agenda of the United Nations, and in that sense, it is of particular importance for students from both the Global South and Global North. Professionals, researchers, and students alike will find this book to be an invaluable resource for understanding and solving problems relating to sustainable urban planning and management.

This section gives a description of notions used throughout this study. Current achievements in developing action-centered ontologies are also discussed. 2.1 Ontologies In the context of information extraction and retrieval, different kinds of ontologies can be distinguished [15]: * Top-level ontologies describe very general concepts like space and time, not depending on a particular domain, * Domain ontologies and task ontologies describe the vocabulary related to a generic domain or kind of task, detailing the terms used in the top-level ontology, * Application ontologies describe the concepts that depend on the particular domain and task within a specific activity. Several investigations have been conducted to bring actions (tasks) to bear on - tologies. Among them are Chandrasekaran et al. [6] and Mizoguchi et al. [23] in the fields of AI and Knowledge Engineering. For the geospatial domain, Kuhn [21] and Raubal and Kuhn [26] have attempted to support human actions in ontologies for transportation. Acknowledging the importance of human actions in the geographic domain, a research workshop was held in 2002, bringing together experts from diff- ent disciplines to share the knowledge and work on this issue [1]. Camara [5], one of the workshop participants, has proposed that action-driven spatial ontologies are formed via category theory, for the case of emergency action plans.

These proceedings contain the papers selected for presentation at the 5th edition of the International Workshop on Web and Wireless Geographical Information Systems, held in December 2005, in Lausanne, Switzerland. The aim of the series of annual W2GIS workshops is to provide an up-to-date review of advances on recent devel- ment and research results in the field of web and wireless geographical information systems. It follows the successful 2001, 2002, 2003, 2004 editions, held in Kyoto, Singapore, Rome and Seoul, respectively. It now represents a young but rapidly - turing research community. In its 5th year, W2GIS reached new heights of recognition as a quality workshop for the dissemination and discussion on latest research and development achievements in the domain. The number of papers received for this workshop demonstrates the growing interest of the research community. There were 70 submissions from 17 countries, many of them of excellent quality and most of them very related to the t- ics of the workshop. Each paper receives three reviews. Based on these reviews, 25 papers were selected for presentation and inclusion in the proceedings. The accepted papers cover a wide range of topics from the Semantic Web, Web personalization, contextual representation and mapping to querying in mobile environments, to mobile networks and location-based services. We had the privilege of having a distinguished invited talk "The next revolution: Peer-to-Peer discovery on mobile devices" by Ouri Wolfson, University of Illinois at Chicago, USA.

2 TheaimoftheannualW GIS workshop is to provide an up-to-date review of advances on recent development of Web and wireless geographical information systems, and new challenges and opportunities for researchers, developers and 2 users in the GIS community. The main topic of the W GIS workshop is theor- ical and technical issues of Web and wireless geographical information systems. This workshop followed the successful 2001, 2002 and 2003 editions, held in - oto, Singapore and Rome, respectively. The 2004 edition was held in Goyang, Korea. 2 In its 4th year, W GIS reached new heights of recognition as a quality wo- shopforthedisseminationanddiscussionofnewwaysofaccessingandanalyzing geospatial information. This year, 39 papers were submitted from 15 countries, and 20 papers were accepted from 11 countries. Similarly, the Program C- mittee consisted of 39 members from 16 countries. We had the privilege of having three distinguished invited talks: "Eliciting User Preferences in Web Urban Spaces," Yanwu Yang and Christophe Cla- munt, Naval Academy Research Institute, France; "Discovering Regional Inf- mation from Web: Localness and Landmark Computation," Katsumi Tanaka, Department of Social Informatics, Graduate School of Informatics, Kyoto U- versity, Japan; and "Towards Knowing, Always and Everywhere, Where - erything Is, Precisely," Christian S.

COSIT,theseriesofConferencesonSpatialInformationTheory,hasbeenaround for more than ten years. Its hallmarks are a fruitful interdisciplinary dialogue between computational and human perspectives on spatio-temporal information and a thorough review process that selects the best papers while giving all - thors detailed feedback on how to develop their work. A clear pro?le of the COSIT community has emerged from the series of conference proceedings, all published as Springer Lecture Notes in Computer Science, and from the per- nent web site at http://www. cosit. info, containing links to the conference web sites and proceedings, a history and program of the series, an impact study, interviews with participants, and pictures. The proceedings of this sixth conference provide ample evidence that COSIT is healthy and maturing, while retaining its youth. Out of the 61 submissions, the program committee selected 26 papers for presentation, in discussions based on at least three double-blind reviews and one or more meta-review from PC members for each paper. Classical COSIT themes, such as spatial reasoning (about distances and directions, regions and shapes) or vagueness are being f- ther re?ned; topics like way?nding and landmarks are boosted by new synergies betweencognitiveandcomputationalapproaches;andthestudyofontologiesfor space and time, a subject since the ?rst COSIT, is gaining more depth.

The goal of How to Make Maps is to equip readers with the foundational knowledge of concepts they need to conceive, design, and produce maps in a legible, clear, and coherent manner, drawing from both classical and modern theory in cartography. This book is appropriate for graduate and undergraduate students who are beginning a course of study in geospatial sciences or who wish to begin producing their own maps. While the book assumes no a priori knowledge or experience with geospatial software, it may also serve GIS analysts and technicians who wish to explore the principles of cartographic design. The first part of the book explores the key decisions behind every map, with the aim of providing the reader with a solid foundation in fundamental cartography concepts. Chapters 1 through 3 review foundational mapping concepts and some of the decisions that are a part of every map. This is followed by a discussion of the guiding principles of cartographic design in Chapter 4-how to start thinking about putting a map together in an effective and legible form. Chapter 5 covers map projections, the process of converting the curved earth's surface into a flat representation appropriate for mapping. Chapters 6 and 7 discuss the use of text and color, respectively. Chapter 8 reviews trends in modern cartography to summarize some of the ways the discipline is changing due to new forms of cartographic media that include 3D representations, animated cartography, and mobile cartography. Chapter 9 provides a literature review of the scholarship in cartography. The final component of the book shifts to applied, technical concepts important to cartographic production, covering data quality concepts and the acquisition of geospatial data sources (Chapter 10), and an overview of software applications particularly relevant to modern cartography production: GIS and graphics software (Chapter 11). Chapter 12 concludes the book with examples of real-world cartography projects, discussing the planning, data collection, and design process that lead to the final map products. This book aspires to introduce readers to the foundational concepts-both theoretical and applied-they need to start the actual work of making maps. The accompanying website offers hands-on exercises to guide readers through the production of a map-from conception through to the final version-as well as PowerPoint slides that accompany the text.

The use of synthetic aperture radar (SAR) represents a new era in remote sensing technology. A complete handbook for anyone who must design an SAR system capable of reliably producing high quality image data products, free from image artifacts and calibrated in terms of the target backscatter coefficient. Combines fundamentals underlying the SAR imaging process and the practical system engineering required to produce quality images from a real SAR system. Beginning with a broad overview of SAR technology, it goes on to examine SAR system capabilities and components and detail the techniques required for design and development of the SAR ground data system with emphasis on the correlation processing. Intended for SAR system engineers and researchers, it is generously illustrated for maximum clarity.

This open access book provides insights into the novel Locally Refined B-spline (LR B-spline) surface format, which is suited for representing terrain and seabed data in a compact way. It provides an alternative to the well know raster and triangulated surface representations. An LR B-spline surface has an overall smooth behavior and allows the modeling of local details with only a limited growth in data volume. In regions where many data points belong to the same smooth area, LR B-splines allow a very lean representation of the shape by locally adapting the resolution of the spline space to the size and local shape variations of the region. The iterative method can be modified to improve the accuracy in particular domains of a point cloud. The use of statistical information criterion can help determining the optimal threshold, the number of iterations to perform as well as some parameters of the underlying mathematical functions (degree of the splines, parameter representation). The resulting surfaces are well suited for analysis and computing secondary information such as contour curves and minimum and maximum points. Also deformation analysis are potential applications of fitting point clouds with LR B-splines.

In cognitive science, mental representations of spatial knowledge are metaphorically referred to as cognitive maps. However, investigations in cognitive psychology reveal that the cognitive map metaphor is inadequate and that more suitable conceptions of human spatial knowledge processing are needed.This book addresses mental processing of knowledge about geographic space from an AI point of view by presenting an experimental computational modeling approach. Results about human memory and visual mental imagery from cognitive psychology are combined with AI techniques of spatial and diagrammatic knowledge processing. The author develops the diagrammatic reasoning architecture MIRAGE as a comprehensive conception of human geographic knowledge processing.

This book is a collection of papers on spatial statistics for remote sensing. The book emerges from a study day that was organized in 1996 at the International Institute for Aerospace Survey and Earth Sciences, ITC, in Enschede, The Netherlands. It was by several means a memorable event. The beautiful new building, according to a design by the famous modern Dutch architect Max van Huet was just opened, and this workshop was the first to take place there. Of course, much went wrong during the workshop, in particular as the newest electronic equipment regularly failed. But the workshop attrackted more than hundred attendants, and was generally well received. The results of the workshop have been published in Stein et al. (1998). The aim of the workshop was to address issues of spatial statistics for remote sensing. The ITC has a long history on collecting and analyzing satellite and other remote sensing data, but its involvement into spatial statistics is of a more recent date. Uncertainties in remote sensing images and the large amounts of data in many spectral bands are now considered to be of such an impact that it requires a separate approach from a statistical point of view. To quote from the justification of the study day, we read: Modern communication means such as remote sensing require an advanced use of collected data. Satellites collect data with different resolution on different spectral bands.

Linking People, Place, and Policy: A GIScience Approach describes a breadth of research associated with the study of human-environment interactions, with particular emphasis on land use and land cover dynamics. This book examines the social, biophysical, and geographical drivers of land use and land cover patterns and their dynamics, which are interpreted within a policy-relevant context. Concepts, tools, and techniques within Geographic Information Science serve as the unifying methodological framework in which landscapes in Thailand, Ecuador, Kenya, Cambodia, China, Brazil, Nepal, and the United States are examined through analyses conducted using quantitative, qualitative, and image-based techniques.

Linking People, Place, and Policy: A GIScience Approach addresses a need for a comprehensive and rigorous treatment of GIScience for research and study within the context of human-environment interactions. The human dimensions research community, land use and land cover change programs, and human and landscape ecology communities, among others, are collectively viewing the landscape within a spatially-explicit perspective, where people are viewed as agents of landscape change that shape and are shaped by the landscape, and where landscape form and function are assessed within a space-time context. This book articulates some of these challenges and opportunities.

The past 20 years can be regarded as the adolescence of geographic information science (GIS), as it grew from a burgeoning area of study into a mature and thriving field. During those two decades, the International Journal of Geographic Information Science (formerly Systems) (IJGIS) was one of the most prominent academic guiding forces in GIScience, and looks to remain so for the foreseeable future. To celebrate this important milestone, Peter Fisher-the second editor of IJGIS-has compiled 19 of the most significant and influential articles ever published in the journal. Classics from IJGIS: Twenty Years of the International Journal of Geographical Information Science and Systems contains articles that shaped the way we approach the science of GIS, provided seeds from which grew key developments that have molded the field, opened new avenues of discovery across the landscape of modern GIScience, and some that may mark how it will change in the future. Accompanying nearly every article is a commentary written by at least one of the original authors. In these commentaries, the authors reflect on various aspects of the original work, including what drove their original research, why the concepts were widely adopted (or in some cases, why not), and what the future may hold for new research embarking on these and similar areas. The 20th article in this collection is an original contribution that examines the social and collaborative networks operating within and shaping the body of research in the field.
