The methods and results analysis of terrain correction in airborne gravity gradiometry surveys
2011
The basic methods and principles of terrain correction in airborne gravity gradiometry surveys are briefly introduced in this paper.And some simulation calculations are presented depended on two kinds of numerical integral formulas which are based on line model of DEM,prism model of DEM.In term of the precise terrain correction of airborne gravity gradiometry surveys,the author calculates the terrain correction using the prism model considering the curvature of earth firstly. Finally,the necessary analysis is showed according to all the data results.
