Description

This paper shows the idea and FORTRAN-77 source code of the division of the digital grid data set into an aggregate of triangular elements to calculate a gravity anomaly. Gravity effect calculated by a sphere model using the technique in this exhibited study was corresponding to the analytic solution well. Because of having come to be able to calculate appropriately and efficiently, calculating the repetition of the correction of the model became comparatively easy. The example that is computing results of the basement structure in Osaka Plain, South-west Japan, by the repetition is shown in this paper.
