The Merlinleigh Sub-basin, 2013 GeoModeller project contains both 3D and 2D geoscientific data and was originally a case history from Intrepid Geophysics’ used to show the capabilities of their data processing software INTREPID, combined with the geological and geophysical modelling package GeoModeller. Subsequent conversions have allowed the product also to be released as a GOCAD model and Geoscience ANALYST visualization. The 3D and 2D data are held in Map Grid of Australia (GDA94) Zone 50 eastings and northings.
