Book excerpt: The advent of highly precise space-based geodetic techniques has led to the application of these techniques to the solution of global earth and ocean problems. Now under consideration is a worldwide network of interconnected fiducial stations where geodetic as well as other scientific measurements can be made. This book discusses the science rationale behind the concept of an extensive global network of fiducial sites. It identifies geophysical problems that cannot be solved without a global approach and cites geodetic objectives that call for a global deployment of fiducial sites. It concludes with operations considerations and proposes a plan for development of the global network.

Book excerpt: In this report, an ad hoc panel of the National Research Council's Committee on Geodesy, Board of Earth Sciences and Resources (1) evaluates the scientific importance of a global network of fiducial sites, monitored very precisely, using a combination of surface- and space-geodetic techniques; (2) examines strategies for implementing and operating such a network; and (3) assesses whether such a network would provide a suitable global infrastructure for geodetic and other geophysical systems of the next century. The panel concludes that a global network of fiducial sites would be a valuable tool for addressing global change issues and play a critical role in providing a reference frame for scientific Earth missions. The panel suggests that existing global networks be integrated and anticipates that such a network would grow from about 30 to the ultimate size of about 200 fiducial sites. It is noted that such a global network will provide a long-term infrastructure for geodetic and geophysical studies. The panel expects that these fiducial sites would evolve into terrestrial observatories or laboratories that would permit more comprehensive studies of the Earth than those now possible.

Available in PDF, EPUB and Kindle. Book excerpt: World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science. Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainabilityâ€"in areas such as human settlements, agriculture, industry, and energyâ€"and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.

Available in PDF, EPUB and Kindle. Book excerpt: Geodesy is the science of accurately measuring and understanding three fundamental properties of Earth: its geometric shape, its orientation in space, and its gravity field, as well as the changes of these properties with time. Over the past half century, the United States, in cooperation with international partners, has led the development of geodetic techniques and instrumentation. Geodetic observing systems provide a significant benefit to society in a wide array of military, research, civil, and commercial areas, including sea level change monitoring, autonomous navigation, tighter low flying routes for strategic aircraft, precision agriculture, civil surveying, earthquake monitoring, forest structural mapping and biomass estimation, and improved floodplain mapping. Recognizing the growing reliance of a wide range of scientific and societal endeavors on infrastructure for precise geodesy, and recognizing geodetic infrastructure as a shared national resource, this book provides an independent assessment of the benefits provided by geodetic observations and networks, as well as a plan for the future development and support of the infrastructure needed to meet the demand for increasingly greater precision. Precise Geodetic Infrastructure makes a series of focused recommendations for upgrading and improving specific elements of the infrastructure, for enhancing the role of the United States in international geodetic services, for evaluating the requirements for a geodetic workforce for the coming decades, and for providing national coordination and advocacy for the various agencies and organizations that contribute to the geodetic infrastructure.

Book excerpt: Published by the American Geophysical Union as part of the Geodynamics Series, Volume 24. There are times in the history of a science when the evolving technology has been combined with a singleness of purpose to make possible the next great step. For space geodesy the decade of the 1980s was one of those times. Initiated in the early 1980s, the NASA Crustal Dynamics Project (CDP), a global venture of unprecedented proportions, exploited new technologies to confirm and refine tectonic theories and to advance geodynamics. The highlights of the efforts of scientists and engineers from some 30 countries are contained in the 54 papers collected in three volumes which are dedicated to the memory of Edward A. (Ted) Flinn, the former Chief Scientist of the NASA Geodynamics Program.

Available in PDF, EPUB and Kindle. Book excerpt: Surveying a Century Ago As it was based on the principles of geometry and trigonometry, surveying may be may be looked upon as a branch of practical mathematics. Hence, it was necessary that land surveyors and hydrographers should have a fair general knowledge, not only of these subjects, but also of all the subjects comprised by the term mathemat ics. In addition, the knowledge of mathematics required in ordinary chain surveying and levelling was not very extensive but in geodetical work, the highest mathematical ability and great organising power were required for a proper conception and supervision of the operations (Threlfall, 1940). Only small area of a few hundred square kilometres can be accurately mapped and surveyed without a frame work, since no difficulty is encountered because of Earth-curvature. In the past, especially in hydrography due to the type of work, surveying was carried out on the principles of ordinary practice, but in a very rough man ner, rapidity of execution being of paramount importance, the permissible error was sometimes large. The relative positions of the main surface features were obtained by aid of portable instruments, such as sextants and lead lines, tide poles, and logships. Sketching, just like military surveying was often filling in the smaller detail. In contrary, survey works done by the national mapping agencies (NMAs) were of a higher-level, and comprised the delimitation of boundaries as well as topographical surveys.

The accuracy of current satellite geodetic data has approached the centimeter level and will improve by one or two orders of magnitude over the next decade. This bodes well for the application of geodetic data to the solution of problems in solid earth, oceanic and atmospheric sciences. The report Geodesy in the Year 2000 addresses many areas of investigation that will benefit from this improvement in accuracy.

Available in PDF, EPUB and Kindle. Book excerpt: Recognizing the increasing importance of the role of gravity and the geoid, and con sidering the substantial synergistic effects which result from close cooperation, the International Gravity Commission and the International Geoid Commission, both scientific bodies of the International Association of Geodesy, decided to hold a Joint Meeting under the common topic "Gravity and Geoid" in Graz, Austria, from Sept. 11 - 17, 1994. The earth's gravity field is increasingly attracting the attention of the geosciences for many reasons. As a response of the earth's internal mass distribution, it significantly helps us to understand the structure of the earth and its dynamics. On the other hand, the earth's gravity field controls the orbits of satellites and is of paramount im portance for accurate orbit prediction'. For geodesy the geoid, representing the gravity field, serves as a unique height reference surface. It is the link between satellite-derived positions and useful geodetic coordinates of utmost precision. For oceanography, the offset of the dynamic ocean surface from the geoid is the signal which bears important information about ocean circulation patterns.

Book excerpt: These proceedings include most of the papers presented at the lAG Sympo sium GPS Trends in Precise Terrestrial, Airborne, and Spacebome Appli cations held in July 1995 during the XXI-th IUGG General Assembly in Boulder, Colorado. The symposium was jointly organized by the lAG and the International Union of Surveys and Mapping (IUSM). The symposium was divided into four sessions, namely (1) The International GPS Service for Geodynamics (IGS) and other Permanent Networks, (2) Spaceborne Applications of the GPS, (3) Kinematic Applications of the GPS, and (4) The GPS and its Relations to Geophysics. The main purpose was to give an overview of the state of the art in 1995 of the applications of the GPS to geodynamics, geodesy, surveying, and navi gation. The call for papers generated a flood of originally more than 70 abstracts; quite a few could be redirected to other symposia, but still 56 papers found their way into these proceedings. We thus conclude that the volume gives a rather complete overview of GPS Trends in Precise Terrestrial, Airborne, and Spacebome Applications in the year 1995.
