Abstract/Summary
This report describes methods for identifying, checking and remediating issues in GSI3D models post calculation using cross-sections and exported surface and thickness grids. These checks are to ensure that the outputted geometry of geological units bear a true resemblance to the lateral and depth extents of those units correlated in GSI3D. The cross-section checks and issues include: • Missing envelopes or cross-section correlations geometries • Lack of correlation nodes on cross-section lines • Wrongly attributed correlation lines in cross-section • Lack of constraint at envelope boundaries The surface and thickness grid checks and issue include: • Bulls-eyes from anomalous correlation points • Holes in the top and base calculated surface • Surface crossovers • Unnatural artefacts in modelled surfaces from cross-sections
