Abstract
A computer system reviews and modifies horizons tentatively defined by a network of pairs of turnings. The curvature for each of the paths of turnings of the network in both the X and Y directions is assessed. If the curvature exceeds a predetermined value in any of the paths, that path is terminated at the point of excessive curvature. Also, each pair of turnings is tested to determine whether it is in a closed loop made up of four turnings which in turn make up four pairs of turnings to determine that there is three-dimensional continuity. The horizons are thereby modified if modification is required.
