Analytical formulation of topographic effects in the second geodetic boundary value problem
Journal of Geodetic ScienceThe second geodetic boundary value problem plays an important role in physical geodesy, as complex mountainous terrain significantly affects its solution, making accurate computation of topographic effects essential for generating a high-precision geoid.

Recent Developments in the Geodetic Boundary Value Problem,
, 1977 Abstract : The report reviews progress in the mathematical formulation and treatment of the geodetic boundary-value problem, in particular, the existence and uniqueness theorems of L. Hormander and the gravity space approach due to F. Sanso. The method of Hormander uses a very advanced inverse function theorem of nonlinear functional analysis.

LINEAR SOLUTIONS OF THE GEODETIC BOUNDARY-VALUE PROBLEM
, 1966 Abstract : The report is concerned with formulas for the determination of the earth's physical surface and external gravity field from free-air gravity anomalies to an approximation linear in the elevation and its derivatives. Part A considers integral equations and their linear solutions; Part B gives an elementary deduction of these solutions from ...
