Realistically representing our three-dimensional world has been the subject of many (philosophical) discussions since ancient times. While the recognition of the globular shape of the Earth goes back to Pythagoras' statements of the sixth century B. C. , the two-dimensional, circular depiction of the Earth's surface has remained prevailing and also dominated the art of painting until the late Middle Ages. Given the immature technological means, objects on the Earth's surface were often represented in academic and technical disciplines by two-dimensional cross-sections oriented along combinations of three mutually perpendicular directions. As soon as computer science evolved, scientists have steadily been improving the three-dimensional representation of the Earth and developed techniques to analyze the many natural processes and phenomena taking part on its surface. Both computer aided design (CAD) and geographical information systems (GIS) have been developed in parallel during the last three decades. While the former concentrates more on the detailed design of geometric models of object shapes, the latter emphasizes the topological relationships between geographical objects and analysis of spatial patterns. Nonetheless, this distinction has become increasingly blurred and both approaches have been integrated into commercial software packages. In recent years, an active line of inquiry has emerged along the junctures of CAD and GIS, viz. 3D geoinformation science. Studies along this line have recently made significant inroads in terms of 3D modeling and data acquisition.

The oceans cover approximately 71% of Earth's surface, 90% of the biosphere and contains 97% of Earth's water. Since the first launch of SEASAT satellite in 1978, an increasing number of SAR satellites have or will become available, such as the European Space Agency's ERS-1/-2, ENVISAT, and Sentinel-1 series; the Canadian RADARSAT-1/-2 and the upcoming RADARSAT Constellation Mission series satellites; the Italian COSMO-SkyMed satellites, the German TERRASAR-X and TANDEM-X, and the Chinese GAOFEN-3 SAR, among others. Recently, European Space Agency has launched a new generation of SAR satellites, Sentinel-1A in 2014 and Sentinel-1B in 2016. These SAR satellites provide researchers with free and open SAR images necessary to carry out their research on the global oceans. The scope of Advances in SAR Remote Sensing of Oceans is to demonstrate the types of information that can be obtained from SAR images of the oceans, and the cutting-edge methods needed for analysing SAR images. Written by leading experts in the field, and divided into four sections, the book presents the basic principles of radar backscattering from the ocean surface; introduces the recent progresses in SAR remote sensing of dynamic coastal environment and management; discusses the state-of-the-art methods to monitor parameters or phenomena related to the dynamic ocean environment; and deals specifically with new techniques and findings of marine atmospheric boundary layer observations. Advances in SAR Remote Sensing of Oceans is a very comprehensive and up-to-date reference intended for use by graduate students, researchers, practitioners, and R&D engineers working in the vibrant field of oceans, interested to understand how SAR remote sensing can support oceanography research and applications.

First established in 1993 with a conference in Elba, Italy, COSIT (the International C- ference on Spatial Information Theory) is widely acknowledged as one of the most - portant conferences for the field of spatial information theory. This conference series brings together researchers from a wide range of disciplines for intensive scientific - changes centered on spatial information theory. COSIT submissions typically address research questions drawn from cognitive, perceptual, and environmental psychology, geography, spatial information science, computer science, artificial intelligence, cog- tive science, engineering, cognitive anthropology, linguistics, ontology, architecture, planning, and environmental design. Some of the topical areas include, for example, the cognitive structure of spatial knowledge; events and processes in geographic space; incomplete or imprecise spatial knowledge; languages of spatial relations; navigation by organisms and robots; ontology of space; communication of spatial information; and the social and cultural organization of space to name a few. This volume contains the papers presented at the 9th International Conference on Spatial Information Theory, COSIT 2009, held in Aber Wrac'h, France, September 21-25, 2009. For COSIT 2009, 70 full paper submissions were received. These papers were carefully reviewed by an international Program Committee based on relevance to the conference, intellectual quality, scientific significance, novelty, relation to previously published literature, and clarity of presentation. After reviewing was completed, 30 papers were selected for presentation at the conference and appear in this volume. This number of papers reflects the high quality of submissions to COSIT this year.

Remote Sensing from Space Supporting International Peace and Security provides the reader with an overview of the state-of-the-art EO related research in the most relevant topics of security research. Whilst focusing on remote sensing technologies the book follows an interdisciplinary approach. It comprises management aspects (Issues and priority of security research, crisis response), applied methodologies and process chains (Treaty monitoring, estimation of population densities and characteristics, border permeability models, damage assessment) and the latest developments in generic tools (feature recognition, change detection and visualization). Contributing authors are leading researchers from private companies, national research institutions and international organizations working together in a European research project GMOSS (Global Monitoring for Security and Stability). Additionally the book tackles the issues of data sharing, data standards and new approaches of training security relevant techniques.

This book is tailored for the scientific community dealing with the application of EO data as well as for project managers and decision makers working in the field of security and having an interest in technical solutions. Many figures and sample images ease reading and allow to quickly grasping the technical background of modern technologies applied in people s security research.

Globalisation has not led to the 'death of geography'. Intensified relations between communities in different parts of the world have only highlighted the need for understanding and managing phenomena on a variety of geographic scales. From global warming to credit crunch, and from epidemics to terrorism, causes and solutions are sought on local, regional, national as well as inter-continental levels. With the advent of Geospatial Technology, scholars, policymakers and entrepreneurs have valuable tools in hand to proceed.

This book offers the first systematic account of the science behind this mental and technological revolution. Tracing the adoption and dissemination of Geospatial Technology in a range of disciplines, it examines the impact this technology has had, and is likely to have, on the explanation of spatial behaviour, phenomena and processes. At the same time, stressing innovative usage, it explores scientific contributions to technology advancement.

This volume contains the papers presented at the International Workshop "Information Fusion and Geographic Information Systems" (IF&GIS'09) held in St. Petersburg, Russia in May 2009. The workshop was organized by the St. Petersburg Institute for Informatics and Automation of the Russian Academy of Sciences (SPIIRAS). The workshop continues a series organised biannually, and attracts academics and industrials from a wide range of disciplines including computer science, geography, statistics, mathematics, hydrography, geomorphology, and environmental sciences. The objective of this workshop is to provide a forum for innovative research oriented towards Geographic Information Science and tech- logies and Corporate Information Systems whose close association highlight novel theoretical and practical challenges. The papers selected by the International Program Committee cover a wide range of innovative areas including ontological and semantic approaches for the representation of geographical data, geographical data monitoring, situation management and forecast, to emerging applications oriented to the maritime environment, disaster management and security threats. While traditional topics of GIS conferences are well represented and still being advanced, several new domains appear and stress the need for the development of versatile monitoring systems and decision making systems. While GIS already have a de facto standard for geographical monitoring and analysis, the papers accepted in this volume also illustrate several novel directions of application whose objective is more closely oriented to process modeling and decision making, and where the nature of the objects represented is revisited using ontological and semantic approaches.

The Association of Geographic Information Laboratories for Europe (AGILE) was established in early 1998 to promote academic teaching and research on GIS at the European level. Since then, the annual AGILE c- ference has gradually become the leading GIScience conference in Europe and provides a multidisciplinary forum for scientific knowledge prod- tion and dissemination. GIScience addresses the understanding and automatic processing of geospatial information in its full breadth. While geo-objects can be represented either as vector data or in raster formats these representations have also guided the research in different disciplines, with GIS researchers concentrating on vector data while research in photogrammetry and c- puter vision focused on (geospatial) raster data. Although there have - ways been small but fine sessions addressing photogrammetry and image analysis at past AGILE conferences, these topics typically played only a minor role. Thus to broaden the domain of topics the AGILE 2009 con- rence it is jointly organized with a Workshop of the International Society of Photogrammetry and Remote Sensing (ISPRS), dedicated to High Re- lution Satellite Imagery, organized by Prof. Christian Heipke of the Le- niz Universitat Hannover. This collocation provides opportunities to explore commonalities - tween research communities and to ease exchange between participants to develop or deepen mutual understanding. We hope that this approach enables researchers from the different communities to identify common - terests and research methods and thus provides a basis for possible future cooperations."

As coastal environments around the world face unprecedented natural and anthropogenic threats, advancements in the technologies that support geospatial data acquisition, imaging, and computing have profoundly enhanced monitoring capabilities in coastal studies. Providing systematic treatment of the key developments, Remote Sensing of Coastal Environments brings together renowned scholars to supply a clear presentation of the state-of-the-art in this technically complex arena. Edited by a recipient of the prestigious PECASE award, this book provides unrivaled coverage of the issues unique to coastal environments. It presents the best available data for measuring and monitoring coastal zones and explains how decision makers and resource managers can use this data to address contemporary issues in coastal zone management. The text illustrates the latest developments in active remote sensing, hyperspectral remote sensing, high spatial resolution remote sensing, the integration of remote sensing and in situ data, and covers the effects of land-cover and land-use change on coastal environments. Complete with representative case studies, this authoritative resource provides a timely snapshot of the wide range of remote sensing applications in coastal issues to enhance the understanding of how increasing disturbances to our coastal regions are affecting the ecological dynamics, biological diversity, and ecosystem health of our coastal environments.

Aerosols have a significant influence on the Earth's radiation budget, but there is considerable uncertainty about the magnitude of their effect on the Earth's climate. Currently, satellite remote sensing is being increasingly utilized to improve our understanding of the effect of atmospheric aerosols on the climate system.

Satellite Aerosol Remote Sensing Over Land is the only book that brings together in one volume the most up-to-date research and advances in this discipline. As well as describing the current academic theory, the book presents practical applications, utilizing state-of-the-art instrumentation, invaluable to the work of environmental scientists.

With contributions by an international group of experts and leaders of correspondent aerosol retrieval groups, the book is an essential tool for all those working in the field of climate change.

This book is the fruition of work from contributors to the Art and Cartography: Cartography and Art symposium held in Vienna in February 2008. This meeting brought together cartographers who were interested in the design and aesthetics elements of cartography and artists who use maps as the basis for their art or who incorporate place and space in their expressions. The outcome of bringing together these like minds culminated in a wonderful event, spanning three evenings and two days in the Austrian capital. Papers, exhi- tions and installations provided a forum for appreciating the endeavors of artists and cartographers and their representations of geography. As well as indulging in an expansive and expressive occasion attendees were able to re? ect on their own work and discuss similar elements in each other's work. It also allowed cartographers and artists to discuss the potential for collaboration in future research and development. To recognise the signi? cance of this event, paper authors were invited to further develop their work and contribute chapters to this book. We believe that this book marks both a signi? cant occasion in Vienna and a starting point for future collabo- tive efforts between artists and cartographers. The editors would like to acknowledge the work of Manuela Schmidt and Felix Ortag, who undertook the task of the design and layout of the chapters.

Most of the papers contained in this volume grew out of presentations given attheInternational Workshop StatGIS03-InterfacingGeostatistics, GISand Spatial Data Bases, which was held in Portschach, Austria, Sept. 29-Oct. 1, 2003, and ensuing discussions, afterwards. Some of the papers are new and have not been given at the conference. Therefore, most of the papers should not be considered as conference proceedings in its original sense but rather moreasself-containedandactualcontributionstothethemeoftheconference, the interfacing between geostatistics, geoinformation systems and spatial data base management. Although some progress has been made toward interfacing, we still feel thatthereisonlylittleoverlapbetweenthedi?erentcommunities.Thepresent volume is intended to provide a bridge between specialists working in di?erent areas. According to the topics of the above mentioned workshop, this volume has been divided into three parts: Part I starts with general aspects of geostatistical model building (Pebesma) and then new methodological developments in geostatics are p- sented, in particular this pertains to neural networks (Parkin and Kanevski), Gibbs ?elds as used in statistical physics (Hristopulos). Furthermore, new - velopments in Bayesian spatial interpolation with skewed heavy-tailed data and new classi?cation methods based on wavelets (Hofer et al.) and support vector machines (Chaouch et al.) are presented.

This chapter has shown a small sample of GIS applications in economic devel- ment. GIS is a powerful tool for data analysis and presentation, and the economic development rami cations are truly signi cant. The speed at which data and stra- gies can be coordinated is clearly changing the way economic developers approach their job. There are a number of important trends that are likely to result in GIS becoming more pervasive in the economic development community. These include declining costs of GIS software, increased computing power, and the growth of Web-based GIS applications. There also has been increase in GIS skills among economic development professionals. References Bastian, L. (2002). Getting the best from the web.

There are more than 70 countries in the world that suffer from the presence of landmines. Annually, between 15,000 and 20,000 people are killed or injured by these mines so there is a pressing need for advances in technology to help to remove them.

Anti-personnel Landmine Detection for Humanitarian Demining reports on state-of-the-art technologies developed during a Japanese National Research Project which ran from 2002 2007. The conventional, and often reliable, method of landmine detection is to use a metal detector to pick up small amounts of metal within the mine. Unfortunately, minefields are frequently strewn with small metal fragments which can camouflage landmines greatly hindering progress using this form of demining. The challenge, then, is to develop practical detection systems that can discriminate between anti-personnel (AP) landmines and randomly scattered innocent metal fragments.

The results of research proposals from universities and industrial sources adopted by the Japan Science and Technology Agency are presented here. This book concentrates on various aspects of three main approaches to AP mine detection:

enhancing and confirming the results of metal-detection scans using ground penetrating radar (GPR);

using robot vehicles and manipulators to operate within minefields remotely; and

methods of sensing the explosives within mines.

Basic results are presented in the fields of GPR, nuclear quadrupole resonance, neutron thermal analysis and biosensors. The integration of these methods for workable robot operation is demonstrated.

The project was carried out in conjunction with mine action centers in Croatia, Cambodia and Afghanistan and evaluation data from field trials of the technologies are also reported.

The results presented by Professor Furuta and his colleagues will be most useful to anyone who is involved in the use or production of technical equipment associated with landmine removal. In addition, academics researching advances in this field and those working in remote sensing, mechatronics and robotics will find much to interest them and a co-ordinated body of work with which to expand their own studies.

In this landmark publication, leading experts detail how remote sensing and related geospatial technologies can be used for coastal ecosystem assessment and management.

This book is divided into three major parts. In the first part several conceptual and technical issues of applying remote sensing and geospatial technologies in the coastal environment are examined. The second part showcases some of the latest developments in the use of remote sensing and geospatial technologies when characterizing coastal waters, submerged aquatic vegetation, benthic habitats, shorelines, coastal wetlands and watersheds. Finally, the last part demonstrates a watershed-wide synthetic approach that links upstream stressors with downstream responses for integrated coastal ecosystem assessment and management.

The chapters in this volume were presented at the July-August 2008 NATO Advanced Study Institute on Unexploded Ordnance Detection and Mitigation. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. For the ninth time we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our eight previous ASI's continued at this meeting. The detection and neutralization of unexploded ordnance (UXO) has been of major concern for very many decades; at least since the First World war. UXO continues to be the subject of intensive research in many ?elds of science, incl- ing mathematics, signal processing (mainly radar and sonar) and chemistry. While today's headlines emphasize the mayhem resulting from the placement of imp- vised explosive devices (IEDs), humanitarian landmine clearing continues to draw signi?cant global attention as well. In many countries of the world, landmines threaten the population and hinder reconstruction and fast, ef?cient utilization of large areas of the mined land in the aftermath of military con?icts.

This publication collects the results of a practical experience of survey, through the direct control of satellite images from high to medium resolution, over areas subjected to desertification problems. The problems of the local population are closely tied to the equilibrium in the management of the territory, which is compromised by the difficulties of maintaining traditional methodologies of management. The new survey technologies, based on the Remote Sensing and Geographic Information System, allow analyzing the details of the present situation and point out the dynamism of the phenomena and the impacts with anthropogenic activities.

Training has been carried out in the Tozeur area, in central Tunisia, where participants had the chance to analyze on the field a series of different aspects. It has also been possible to discuss similar experiences in distant territories and the importance of the physical processes of desertification. During the development of the intensive training on the job, visits to entrepreneurial truths concerning the management of the territory have been carried out. The analyzed area finds in tourism an answer to the necessities of improving the living conditions of the population.

Specialists from twelve nations presented actions of management of the territory, with detailed attention on environmental security and the conditions of the territory. From the observations carried out the fragility of the landscape of the oases has emerged, which are subjected to total anthropogenic management and therefore closely linked to the availability of the specialized workers in the traditional methodologies. It is natural that the management of the lands changesaccording to modern technologies, but, with a too fast pace, this evolution risks to upset the management of the territory. The exchange of information, the ability to map the variations, the dialogue between the parts, will favor the maintenance of the political security in the Mediterranean region. This experience of cooperation and association constitutes a precedent for the development of a system of high education courses to be provided to the local communities for the common wellbeing.

The 8th edition of the International Symposium on Web and Wireless Geograp- cal Information Systems (W2GIS 2008) was held in December 2008, in the vibrant city of Shanghai, China. This annual symposium aims at providing a forum for discussing advances on recent developments and research results in the ?eld of Web and wireless geographical information systems. Promoted from workshop to s- posium in 2005, W2GIS now represents a prestigious event within this dynamic research community. These proceedings contain the papers selected for presen- tion at this international event. For the 2008 edition, we received 38 submissions from 16 countries. All subm- ted papers were related to topics of interest to the symposium. Each paper received three reviews. Based on these reviews, 14 papers were selected for presentation and inclusion in the proceedings. The accepted papers are all of excellent quality and cover topics that range from mobile networks and location-based services, to contextual representation and mapping, to geospatial Web techniques, to object tracking in Web and mobile environments. We wish to thank all authors that contributed to this symposium for the high quality of their papers and presentations. Our sincere thanks go to Springer's LNCS team. We would also like to acknowledge and thank the Program C- mittee members for the quality and timeliness of their reviews. Finally, many thanks to the Steering Committee members for providing continuous support and advice.

This book provides a general overview of research activities related to locati- based services. These activities have emerged over the last years, especially around issues of positioning, sensor fusion, spatial modelling, cartographic communi- tion as well as in the ? elds of ubiquitious cartography, geo-pervasive services, user-centered modelling and geo-wiki activities. The innovative and contemporary character of these topics has led to a great variety of interdisciplinary contributions, from academia to business, from computer science to geodesy. Topics cover an enormous range with heterogenous relationships to the main book issues. Whilst contemporary cartography aims at looking at new and ef? cient ways for com- nicating spatial information, the development and availability of technologies like mobile networking, mobile devices or short-range sensors lead to interesting new possibilities for achieving this aim. By trying to make use of available technologies, cartography and a variety of related disciplines look speci? cally at user-centered and context-aware system development, as well as new forms of supporting way? nding and navigation systems. The contributions are a selection of full reviewed papers submitted to the th 5 Conference on Location Based Services and TeleCartography in Salzburg November 2008, jointly organized by Salzburg Research and Vienna University of Technology, Research Group Cartography. The production of this book would not have been possible without the prof- sional and formidable work of Manuela Schmidt and Felix Ortag. The editors are grateful for their help as well as for the help of Sven Leitinger.

Wind erosion occurs in many arid, semiarid and agricultural areas of the world. It is an environmental process in?uenced by geological and climatic variations as well as human activities. In general, wind erosion leads to land degradation in agricultural areas and has a negative impact on air quality. Dustemissiongeneratedbywinderosionisthelargestsourceofaerosolswhich directly or indirectly in?uence the atmospheric radiation balance and hence global climatic variations. Strong wind-erosion events, such as severe dust storms, may threaten human lives and cause substantial economic damage. The physics of wind erosion is complex, as it involves atmospheric, soil and land-surface processes. The research on wind erosion is multidisciplinary, covering meteorology, ?uid dynamics, soil physics, colloidal science, surface soil hydrology, ecology, etc. Several excellent books have already been written about the topic, for instance, by Bagnold (1941, The Physics of Blown Sand and Desert Dunes), Greeley and Iversen (1985, Wind as a Geological P- cess on Earth, Mars, Venus and Titan), Pye (1987, Aeolian Dust and Dust Deposits), Pye and Tsoar (1990, Aeolian Sand and Sand Dunes). However, considerable progress has been made in wind-erosion research in recent years and there is a need to systematically document this progress in a new book.

Due to their unique geophysical and geodynamic environment, both the Arctic and Antarctic polar regions are often utilized for geodetic and geophysical observations. This book is a collection of papers on various aspects of the scientific investigation and observation techniques of the polar regions at both temporary and permanent observatories. Most papers focus on regional models based on data acquired in polar regions. Geodetic satellite positions systems (GNSS: GPS, GLONASS, GALILEO) will also be discussed as well as other space techniques (DORIS, VLBI). Gravimetry, absolute gravimetry, and tidal gravimetry are also discussed, as well as seismology and meteorology. The book also touches on data analysis and geodynamic interpretation and discusses methods of constructing autonomous observatories.

This book contains selected papers from participants at the 4th National Cartographic Conference GeoCart'2008, held in Auckland, New Zealand in September 2008. It provides a contribution to the literature related to contemporary Geoinformation and Cartography as part of the Springer - ries "Lecture Notes in Geoinformation and Cartography." The series aims to provide publications that highlight the research and professional acti- ties taking place in this exciting discipline area. Books published thus far cover a wide range of topics and their content reflects the diverse nature of interests of contributors in the field. The GeoCart conferences are held every two years and attract attendees from Australasia and globally. They offer a forum for reflecting on past practices, exploring future possibilities and reporting on the findings of - search undertakings. They make valuable contributions to the theory and praxis of Geoinformation and Cartography. The editors of this book, Antoni Moore, from the University of Otago, and Igor Drecki, from the University of Auckland, have provided contri- tions that fall under the categories of representation, egocentric mapping, the exploration of tangible and intangible geographical phenomena by v- ual means and Web mapping. The chapters provide valuable information from contributors that illustrate the exciting developments in the dis- pline. I applaud the efforts of the editors and authors for providing this work as an insight into their fields of activity. I hope that you find this book, from the land of the Long White Cloud, a valuable resource.

This book is a composition of diverse points of view regarding the application of Computational Intelligence techniques and methods into Remote Sensing data and problems. It is the general consensus that classi?cation, and related data processing, and global optimization methods are the main topics of Compu- tional Intelligence. Global random optimization algorithms appear in this book, such as the Simulated Annealing in chapter 6 and the Genetic Algorithms p- posedinchapters3and9. Muchofthecontentsofthe bookaredevotedto image segmentationandrecognition, using diversetoolsfromregionsofComputational Intelligence, ranging from Arti?cial Neural Networks to Markov Random Field modelling. However, there are some fringe topics, such the parallel implem- tation of some algorithms or the image watermarking that make evident that thefrontiersbetweenComputationalIntelligenceandneighboringcomputational disciplines are blurred and the fences run low and full of holes in many places. The book starts with a review of the current designs of hyperspectral sensors, more appropriately named Imaging Spectrometers. Knowing the shortcomings and advantages of the diverse designs may condition the results on some app- cations of Computational Intelligence algorithms to the processing and und- standing of them Remote Sensing images produced by these sensors. Then the book contentsmovesinto basic signalprocessing techniquessuch ascompression and watermarking applied to remote sensing images. With the huge amount of remotesensinginformationandtheincreasingrateatwhichitisbeingproduced, itseems only naturalthatcompressiontechniques willleapintoa prominentrole in the near future, overcoming the resistances of the users against uncontrolled manipulation of "their" data. Watermarkingis the way to address issues of o- ership authentication in digital contents.
