Fourier Techniques in Physical Geodesy: A Fundamental Approach

摘要

Recently the use of Fourier techniques in physical geodesy has becomeincreasingly popular. In miscellaneous studies the method has been proven to be unrivalled in computation efficiency in cases where a large amount of data in a limited area is concerned. Only in very few cases an attempt has been made to start from the basics of potential theory and work out the Fourier solution without too much concessions to rigour. In the study such a derivation is presented. The effects of the discrete, finite boundary values (observations), and the planar approximation follow quite naturally and the method as a whole becomes more accessible.
