Sažetak
Simple spatial density model was implemented in the planar terrain correction (tc) approximation. The methods of exact numerical integration and Fast Fourier Transform for the tc quadratic approximation were redefined to include, besides height and surface density models, the subsurface horizon's depth and density digital models as well. The redefined methods were compared with numerical integration and FFT methods in which only surface variable density model was utilized. The relationship between the redefined spatial and spectral domain methods was investigated, as well their sensitivity to the chosen density model. The superior time efficiency of the FFT was confirmed. It was shown that the terrain correction with proposed spatial density model could be used in solving physical geodesy problems.
