This book was released on 2014 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demonstration of accuracy of the developed geoid model, which is compared to GPS/leveling, shows the model based on the gravity anomaly with respect to the terrain effects have better accuracy than the model based on the free-air gravity anomaly. The achievement on the precision of geoid undulation, computed on a 2 arcmin grid, is 5.6 cm in standard deviation. This model is based on the airborne-only gravity data considering not only the terrain effects but also the downward continuation. The bias in the gravimetric geoid of about 15.5 cm, determined from the comparison with the GPS/leveling data, agrees with previously determined values.

Available in PDF, EPUB and Kindle. Book excerpt: This open access volume contains selected papers of the 2021 Scientific Assembly of the International Association of Geodesy – IAG2021. The Assembly was hosted by the Chinese Society for Geodesy, Photogrammetry and Cartography (CSGPC) in Beijing, China from June 28 to July 2, 2021. It was a hybrid conference with in-person and online attendants. In total, the Assembly was attended by 146 in-person participants and 1,123 online participants. The theme of the Assembly was Geodesy for a Sustainable Earth. 613 contributions (255 oral presentations and 358 poster presentations) covered all topics of the broad spectrum considered by the IAG: geodetic reference frames, Earth gravity field modelling, Earth rotation and geodynamics, positioning and applications, the Global Geodetic Observing System (GGOS), geodesy for climate research, marine geodesy, and novel sensors and quantum technology for geodesy. All published papers were peer-reviewed, and we warmly recognize the contributions and support of the Associate Editors and Reviewers.

Download or read book Geoid Determination written by Fernando Sansò and published by Springer Science & Business Media. This book was released on 2013-02-13 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will be based on the material of the lecture noties in several International Schools for the Determination and Use of the Geoid, organized by the International Geoid Serivice of the International Association of Geodesy. It consolidates, unifies, and streamlines this material in a unique way not covereed by the few other books that exist on this subjext. More specifically, the book presents (for the first time in a single volume) the theory and methodology of the most common technique used for precise determination of the geoid, including the computation of the marine geoid from satellite altimetry data. These are illustrated by specific examples and actual computations of local geoids. In addition, the book provides the fundamentals of estimating orthometric heights without spirit levelling, by properly combining a geoid with heights from GPS. Besides the geodectic and geophysical uses, this last application has made geoid computation methods very popular in recent years because the entire GPS and GIS user communities are interested in estimating geoid undulations in order to convert GPS heights to physically meaningful orthometric heights (elevations above mean sea level). The overall purpose of the book is, therefore, to provide the user community (academics, graduate students, geophysicists, engineers, oceanographers, GIS and GPS users, researchers) with a self-contained textbook, which will supply them with the complete roadmap of estimating geoid undulations, from the theoretical definitions and formulas to the available numerical methods and their implementation and the test in practice.

Book Synopsis Local and Regional Geoid Determination from Vector Airborne Gravimetry by : Juan Gilberto Serpas
Download or read book Local and Regional Geoid Determination from Vector Airborne Gravimetry written by Juan Gilberto Serpas and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The local geoid in a test area in the Canadian Rocky Mountains is computed using airborne gravimetry data. The geoid is computed by using the vertical and horizontal components (VC and HC) of the gravity disturbance vector. In addition, the combination of the three components by least squares collocation (LSC) is done. The use of crossovers to estimate biases and trends in the gravity signals, and the use of minimal control as constraints in the crossover adjustment are studied. Moreover, the downward continuation and direct and indirect effects due to removal and restoration of masses are investigated. An expression for the effect of the masses applied to disturbing potential is provided. Geoid estimates coming from VC and HC, computed using Hotine's and line integral, show the same level of accuracy when compared to the Canadian geoid. Relative accuracies on the order of 3 to 7 cm for the VC geoid, and of 4 to 12 cm for the HC geoid are achieved. The VC geoid suffers from edge effects on the results, while the HC geoid is highly dependent on ground control. Regarding the estimation of the geoid by LSC, using the three components of the gravity disturbance vector (3C-LSC), we observe differences in the range of 4 to 6 cm, with respect to the Canadian geoid. Comparing the 3C-LSC geoid with the VC geoid using Hotine's integral, the 3C-LSC are comparable and improved for some lines. In general the result from the 3C-LSC are better than those from HC, by line integral. On the other hand, the use of only the vertical component by least squares collocation (VC-LSC) provides, in general, better results than those from 3C-LSC, and those from the VC and HC by the use of Hotine's and line integral. We could expect better results for the case of 3C-LSC if we are able to improve the quality of the measured horizontal components of the gravity disturbance vector. The application of a wave correlation filter to both HC and VC geoids show promising results for the improvement of the accuracy of the combined geoid.
