Terrain analysis has been an active study field for years and attracted research studies from geographers, surveyors, engineers and computer scientists. With the rapid growth of Geographical Information System (GIS) technology, particularly the establishment of high resolution Digital Elevation Models (DEM) at national level, the challenge is now focused on delivering justifiable socio-economical and environmental benefits. The contributions in this book represent the state of the art of terrain analysis methods and techniques in areas of digital representation, morphological and hydrological models, uncertainty and applications of terrain analysis.

Homeland security and context In the Geographical Dimensions of Terrorism (GDOT) (Cutter et al. 2003), the first book after 9/11 to address homeland security and geography, we developed several thematic research agendas and explored intersections between geographic research and the importance of context, both geographical and political, in relationship to the concepts of terrorism and security. It is good to see that a great deal of new thought and research continues to flow from that initial research agenda, as illustrated by many of the papers of this new book, entitled Geospatial Technologies and Homeland Security: Research Frontiers and Future Challenges. Context is relevant not only to understanding homeland security issues broadly, but also to the conduct of research on geospatial technologies. It is impossible to understand the implications of a homeland security strategy, let alone hope to make predictions, conduct meaningful modeling and research, or assess the value and dangers of geospatial technologies, without consideration of overarching political, social, economic, and geographic contexts within which these questions are posed.

As the United States grew into an empire in the late nineteenth century, notions like "sea power" derived not only from fleets, bases, and decisive battles but also from a scientific effort to understand and master the ocean environment. Beginning in the early nineteenth century and concluding in the first years of the twentieth, Jason W. Smith tells the story of the rise of the U.S. Navy and the emergence of American ocean empire through its struggle to control nature. In vividly told sketches of exploration, naval officers, war, and, most significantly, the ocean environment, Smith draws together insights from environmental, maritime, military, and naval history, and the history of science and cartography, placing the U.S. Navy's scientific efforts within a broader cultural context. By recasting and deepening our understanding of the U.S. Navy and the United States at sea, Smith brings to the fore the overlooked work of naval hydrographers, surveyors, and cartographers. In the nautical chart's soundings, names, symbols, and embedded narratives, Smith recounts the largely untold story of a young nation looking to extend its power over the boundless sea.

This book covers fundamental aspects of spatial data modelling specifically on the aspect of three-dimensional (3D) modelling and structuring. Realisation of "true" 3D GIS spatial system needs a lot of effort, and the process is taking place in various research centres and universities in some countries. The development of spatial data modelling for 3D objects is the focus of this book.

This book is addressed to students and professionals and it is aimed to cover as much as possible the wider region of topographic mapping as it has been evolved into a modern field called geospatial information science and technology. More emphasis is given to the use of scientific methods and tools that are materialised in algorithms and software and produce practical results. For this reason beyond the written material there are also many educational and professional software programs written by the author to comprehend the individual methodologies which are developed. Target of this book is to provide the people who work in fields of applications of topographic mapping (environment, geology, geography, cartography, engineering, geotechnical, agriculture, forestry, etc.) a source of knowledge for the wider region so that to help them in facing relevant problems as well as in preparing contracts and specifications for such type of work assigned to professionals and evaluating such contracting results. It is also aimed to be a reference of theory and practice for the professionals in Topographic Mapping. This book applies a didactics method where with a relatively small effort someone can digest a quite large volume of simple or complicated material of knowledge at a desirable scientific depth within a relative short time interval. The objective that educated people must be "smarter than the machine" and not to treat the machine as a "black box" being "button pushers" has been achieved, through the author's experience in USA and Greece, with relative success by adopting this didactics technique. There are 11 chapters and two Appendices including: Reference systems and Projections, Topographic instruments and Geometry of coordinates, Conventional construction of a topographic map, Design and reproduction of a thematic map, Digital Topographic mapping - GIS, Digital Terrain Models (DTM / DEM), GPS, methods of Photogrammetry, Remote Sensing, new technologies LIDAR, IFSAR, the method of Least Squares adjustment, Description of educational software accompanying the text.

The book covers the international state-of-the-art research in the field of 3D geo-information modeling. It focuses on comparing several types of 3D models. Due to the rapid developments in sensor techniques more and more 3D data becomes available. Effective algorithms for (semi) automatic object reconstruction are required. 3D analysis and 3D simulation techniques explore and extend the possibilities in spatial applications.

This book provides for the first time a general overview of research activities related to location and map-based services. These activities have emerged over the last years, especially around issues of positioning, spatial modelling, cartographic communication as well as in the fields of ubiquitious cartography, geo-pervasive services, user-centered modelling and geo-wiki activities. The innovative and contemporary character of these topics has lead 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 efficient ways for communicating 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 specifically at user-centered and conte- aware system development, as well as new forms of supporting wayfinding and navigation systems. Contributions are provided in five main sections and they cover all of these aspects and give a picture of the new and expanding field of Location Based Services and TeleCartography.

This book expands the current frame of reference of remote sensing and geographic information specialists to include an array of socio-economic and related planning issues. Using remotely sensed data, the project explores the efficacy and policy implications of new approaches toward analyzing data, integrates approaches from human geography and explores the utility of employing geo-technologies to further the politics of local growth and smart growth coalitions, as in green space programs.

This book describes an integrated approach to using remotely sensed data in conjunction with geographic information systems for landscape analysis. Remotely sensed data are compressed into an analytical image-map that is compatible with the most popular geographic information systems as well as freeware viewers. The approach is most effective for landscapes that exhibit a pronounced mosaic pattern of land cover. The image maps are much more compact than the original remotely sensed data, which enhances utility on the internet. As value-added products, distribution of image-maps is not affected by copyrights on original multi-band image data.

Multimedia Cartography provides a contemporary overview of the issues related to multimedia cartography and the design and production elements that are unique to this area of mapping. The book has been written for professional cartographers interested in moving into multimedia mapping, for cartographers already involved in producing multimedia titles who wish to discover the approaches that other practitioners in multimedia cartography have taken and for students and academics in the mapping sciences and related geographical fields wishing to update their knowledge about current issues related to cartographic design and production. It provides a new approach to cartography one based on the exploitation of the many rich media components and avant-garde approach that multimedia offers."

New and more accurate techniques for satellite gravimetry will be available soon, with promising applications in Earth sciences. With this special issue the authors want to stimulate discussion among Earth scientists on objectives and preferences for future satellite gravimetry missions. This is an urgently needed discussion. Visions for follow-on missions have to be developed today, if they are to be realized within 10 years, given the required preparation time of such satellite missions.

In view of the growing interest in maps and charts as brought about by the interrelation of countries and communities, the purpose of this publication is to supply in outline form the underlying principles of constructive cartography. It is also intended to illustrate the development of the scientific system of today and the educational value of this branch of human activities. A knowledge of the horizontal and vertical location of places and the configuration of the earth's surface are essential factors in carrying on the major activities of a nation. Such information as relates to land surfaces is given on the modern topographic map; the submarine relief and the navigational routes of travel and commerce are supplied by the nautical chart, and, in a similar manner, the needs of air travel and air commerce are served by the aeronautical chart. A nation of vast resources and industrial developments can well afford to provide maps and charts for the extension of its highways, railroads, and airways in all directions; for the harnessing of its rivers to furnish water power and irrigation; and for providing means of protection against the overflow of river banks and the encroachments of the sea upon its beaches. In the interests of navigation the mariner requires charts that supply not only the necessary accuracy in delineation and facility for use, but charts that are in keeping with the development of a nation's ports, its commerce, and the ever changing natural conditions. It is the purpose of this book to trace briefly the attempts made through the ages to depict on paper accurate geographic information which will lead to a better understanding of the terrain and the sea, their historyand relationship, their characteristics and phenomena. It will also outline what are now considered the best methods of securing and utilizing map data and to indicate how to use the maps and charts after they have been constructed and printed.

The development of wireless telecommunication and ubiquitous computing te- nologies has led to a growing mobile population and dramatically changed p- terns of working and everyday life. A smooth and safe mobility is only possible when the mobile person is well-informed of the happenings in his ambient en- ronments. Location-sensitive maps have proved a strong enhancement to what a mobile user can directly perceive from his ambient environments. Since ancient times the map has been the favorite communication language of spatial infor- tion. It is even more the case for mobile applications where brand-new maps can be wirelessly retrieved or generated in real-time. The upsurge of map-based s- vices on mobile devices has raised a number of new questions challenging the conventional computer-assisted cartography. Map-based mobile services provides a contemporary overview of research and development issues related to the design and the use of mobility-supporting maps. The book has been written for professional cartographers who are striving for - tending their theoretical, methodological and practical knowledge to mobile m- making, for surveyors and geo-service providers involved in the development of intelligent location-based services, for software developers and cognitive scientists engaged in human-computer interaction, and for students and academics in cart- raphy and geoinformation sciences. The book was initiated by the multidisciplinary workshop "Design of m- based mobile services" within the frame of the conference "Human and Computer 2003 - Interaction on the movement" held in Stuttgart, Germany, September 2003.

This book focuses on the integration of spatial statistics, GIS-technology, ecosystem studies, and scenario modelling. Its main aim is to extend the information gained at the stand level to larger spatial scales, i.e. to forest districts, forest landscapes or to the total area of Lower Saxony. The studies demonstrate the potential and limitations of regionalization approaches for forest ecological variables. The results provide valuable spatial information for forest managers and landscape planners as well as for policy-makers. Some spatial models outlined in this book have been implemented as useful tools in present forest management. With current improvements of data quality, e.g. from remote sensing and refined ground-based inventories, methods are now available to develop large-scale approaches to forest ecology and management. This book is an indispensable tool for scientists and those involved in forest management.

The book is an introduction to practical astrometry, dealing with the determination of positions, motions, distances and dimensions of celestial bodies ranging from quasars to artificial satellites. The main part is devoted to the description of instruments and observing techniques, and also includes the basic properties of optical instruments and a detailed description of the atmospheric effects on observations. A brief summary of the main phenomena in positional astronomy and of data treatment is given. Although classical astrometric methods are described, emphasis is put on new, more precise techniques such as CCD, optical and radio interferometry, space astrometry, etc. For this 2nd edition, the release of the Hipparcos and Tycho catalogs, the rise in CCD astrometry and the adoption of a new celestial reference frame by the IAU led to a significant modification of the text. And, especially, the outlook for astrometry has been completely rewritten.

Digital manipulation of landform is revolutionizing how our built environment is designed and constructed. On a technical level, three dimensional geometric modeling of topography has its origins at the interface of geographic information systems (GIS) and computer aided geometric modeling (CAD): the former with its representations of spatial attribute information with digital terrain in several representations (Triangulated Irregular Networks, contour lines, etc. ); the latter focusing primarily on the parameterization and combination of geometric primitives. The broadening of these two disciplines to embrace new surveying and navigation advances, e. g. global positioning systems (GPS), together with developments in engineering on the application side, are leading to powerful new suites of functionality. There has been a pronounced need for a forum where these traditionally separate parties can interact. These proceedings contain the technical papers selected and formally presented as part of the scientific program of the First International Symposium on Digital Earth Moving, 2001 (DEM 2001) held September 5 7, 2001 at the CIM Institute for Computing Science and Industrial Technologies of the University of Applied Science of Southern Switzerland (SUPSI iCIMSI) in Manno (Lugano), Switzerland. It is the first volume published on this explicit theme. Thirty six submissions were received, from fifteen countries, with thirteen select papers and posters presented in the official program and in this publication.

Maps make the world visible, but they also obscure, distort, and idealize. This wide-ranging study traces the impact of cartography on the changing cultural meanings of space. Combining cartographic history with crucial cultural studies and literary analysis, this book examines the construction of social and political space in maps, in cosmography and geography, in historical and political writing, and in he literary works of Marlowe. Shakespeare, Spenser, and Drayton.

This collection of conference papers describes state-of-the-art methodologies and algorithms used in the treatment of inverse problems, focusing on seismology and image processing. The papers also describe new general methodologies for analysis and solution of inverse problems by means of statistical and deterministic algorithms. The book gives a glimpse of recent techniques, many of which are still under development.

Geomatics is an amalgam of methods, algorithms and practices in handling data referred to the Earth by informatic tools. This book is an attempt to identify and rationally organize the statistical-mathematical methods which are common in many fields where geomatics is applied, like geodesy, geophysics and, in particular, the field of inverse problems and image analysis as it enters into photogrammetry and remote sensing.These lecture notes aim at creating a bridge between people working in different disciplines and making them aware of a common methodological basis.

Spatialcognitionisconcernedwiththewayshumans,animals,ormachinesthink about real or abstract space and also with the ways spatial structures can be used for reasoning. Thus, space is considered both, as an object of cognition and as ameans of cognition.

This is the second volume published in the framework of the Spatial Cog- tion Priority Program. It augments the results presented in Freksa et al. 1998.

This book describes the discovery of the stratosphere itself and of various unexpected phenomena in the stratosphere: e.g., a manned balloon flight in 1901 as high as 11 km; an expedition to Lake Victoria in Africa in 1908 which found inexplicable west winds in the stratosphere above the equator; and the discovery of the ozone layer in the 1930s, the Berlin Phenomenon in 1952, the Quasi-Biennial Oscillation in 1960, the influence of volcanic eruptions in 1970, the ozone hole in 1984, and the influence of the 11-year solar cycle in 1987. The book also describes how these phenomena are connected with each other and how they create variability in the climate system, in addition to man-made changes, such as the decrease in ozone. We use the stratosphere as one example of Nature's complexity and of how often discoveries are ignored because they do not fit prevalent concepts.

One of the most beautiful maps to survive the Great Age of Discoveries, the 1513 world map drawn by Ottoman admiral Piri Reis is also one of the most mysterious. Gregory McIntosh has uncovered new evidence in the map that shows it to be among the most important ever made.

This detailed study offers new commentary and explication of a major milestone in cartography. Correcting earlier work of Paul Kahle and pointing out the traps that have caught subsequent scholars, McIntosh disproves the dubious conclusion that the Reis map embodied Columbus's Third Voyage map of 1498, showing that it draws instead on the Second Voyage of 1493-1496. He also refutes the popular misinterpretation that Reis's depictions of Antarctica are evidence of either ancient civilizations or extraterrestrial visitation. McIntosh brings together all that has been previously known about the map and also assembles for the first time the translations of all inscriptions on the map and analyzes all place-names given for New World and Atlantic islands. His work clarifies long-standing mysteries and opens up new ways of looking at the history of exploration.

Due to plate motions, tidal effects of the Moon and the Sun, atmosphe ric, hydrological, ocean loading and local geological processes, and due to the rotation of the Earth, all points on the Earth's crust are sub ject to deformation. Global plate motion models, based on the ocean floor spreading rates, transform fault azimuths, and earthquake slip vectors, describe average plate motions for a time period of the past few million years. Therefore, the investigation of present-day tectonic activities by global plate motion models in a small area with complex movements cannot supply satisfactory results. The contribution of space techniques Very Long Baseline Interferome try (VLBI); Satellite Laser Ranging (SLR); Global Positioning System (GPS)] applied to the present-day deformations ofthe Earth's surface and plate tectonics has increased during the last 20 to 25 years. Today one is able to determine by these methods the relative motions in the em to sub-em-range between points far away from each other."

This elegant little book discusses a famous problem that helped to define the field now known as topology: What is the minimum number of colors required to print a map such that no two adjoining countries have the same color, no matter how convoluted their boundaries. Many famous mathematicians have worked on the problem, but the proof eluded fomulation until the 1950s, when it was finally cracked with a brute-force approach using a computer. The book begins by discussing the history of the problem, and then goes into the mathematics, both pleasantly enough that anyone with an elementary knowledge of geometry can follow it, and still with enough rigor that a mathematician can also read it with pleasure. The authors discuss the mathematics as well as the philosophical debate that ensued when the proof was announced: Just what is a mathematical proof, if it takes a computer to provide one -- and is such a thing a proof at all?
