Precise Geodetic Infrastructure


Book Description

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.




Contributions of Space Geodesy to Geodynamics


Book Description

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.







Geodesy and Physics of the Earth


Book Description

The investigation of the kinematics and dynamics of the Earth has achieved remarkable progresses in the last decades in understanding and explaining a large variety of geo- dynamical, geophysical and geological phenomena. The impact of increasingly precise geodetic space-time measurements and analyses have much contributed to these results. Papers presented atthe 7th International Symposium on Geodesy and Physics of the Earth focus onfour topics: - Present Day Tectonic Motions - Gravity Field and its Variation - Earth Rotation Characteristics - International Programs for Geodesy and Geodynamics Researchers and advanced students may use this volume as a comprehensive reference of concepts, techniques and results.




GPS for Geodesy


Book Description

An in-depth description of the theory and mathematical models behind the application of the global positioning system in geodesy and geodynamics. The contributions by leading experts in the field ensure a continuous flow of ideas and developments. The mathematical models for GPS measurements are developed in the first half of the book, and these are followed by GPS solutions for geodetic applications on local, regional and global scales.
