Download or read book Global Geoid and Gravity Anomaly Predictions Using the Collocation and Point Mass Techniques written by Robert P. Bessette and published by . This book was released on 1984 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: We previously described (14,14) spherical-harmonic global adjustments of satellite altimetry using the AFGL short-arc technique supplemented with point masses to allow incorporation of short-wavelength geoidal detail. Recently, we have also investigated another technique to enhance short-wavelength detail: least squares collocation with noise. Both methods provide a means to determine a high resolution gravity field on a local, regional or global scale. Statistical comparisons of these two methods have been made in selected areas and the results tabulated.

Available in PDF, EPUB and Kindle. Book excerpt: A Bouguer Gravity Anomaly Map of Africa has been compiled using only terrestrial data. The map is a contoured representation of one degree x one degree mean anomaly values. Some one degree x one degree values are computed by conventional or statistical means directly from observed gravity data held at DMAAC in the DOD Gravity Library. The majority of the one degree x one degree values are predicted by geophysical-gravity correlation methods. The anomaly pattern shown on the map is discussed and evaluated with respect to regional and local tectonic and geologic patterns. The entire Bouguer anomaly map is computer generated and drawn by an electronic plotting device. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Mean gravity anomaly values which represent 1 degree x 1 degree surface areas can be predicted on the continents by geophysical gravity correlation methods whether or nor measured gravity data exists within those 1 degree x 1 degree areas. These methods take into consideration the earth's structure, composition, and response to changes in surficial mass distribution by means of observed or computed correlations between gravity and other geophysical parameters within geologic/tectonic provinces. Linear basic prediction functions, used to describe and predict the relationships between gravity and elevation, are shown to be a natural consequence of the properties of gravity reduction procedures and the observed behavior of gravity anomalies within structurally homogeneous regions.

Download or read book Accuracy of Mean Gravity Anomalies Obtained from Point and Profile Measurements written by Helmut Moritz and published by . This book was released on 1963 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean gravity anomalies for a certain rectangular area (block) can be computed from observed point or profile gravity values using some interpolation method (e.g., representation or least squares interpolation). If the covariance function of the gravity anomalies is known and the interpolation method is specified, then the accuracy (standard error and error covariance) of the mean anomalies can be computed without any additional numerical data. The formulas for this purpose are evaluated numerically for different sizes of blocks and different interpolation methods using an estimate for the covariance function. The integrals involved are approximated by summations performed by a highspeed computer. The results show the accuracies obtainable with a given observational material, by different interpolation methods. They are useful for numerical studies on the error propagation in the computation of gravimetric quantities (e.g., geoid undulations). (Author).
