On determination of gravimetric transformations
© Dubovenko Yu.I.
Exact gravity transforms in the regional studies are determined by the solution of nonlinear boundary-value Alexidze problem for the gravity potential. The errors of its substitution by the appropriate problem for the Laplace's equation have been estimated. The accuracy of its solution extremely depends on the problem's conditioning, approximations of the required gradient direction, parameters of numerical calculus and direction of the external normal, along which the proper derivatives are calculated.
