ON THE IMPROVEMENT OF GRAVITY FIELDMODEL USING REGIONAL GRAVITY DATA
Shi Pan(Xi'an Research Institute of Surveying and Mapping, 710054)
:The theory and method for improvement of the coefficient of a known gra-vity field model using regional gravity data are shown systematically in thispaper. This problem is essentially of combined use of gravity anomalies andpotential coefficients. Two methods, the combined adjustment and the regionalintegral correction, are presented. The frequency weight combined method isdiscussed in datail.
