GeoModeller provides a complete suite of 3D interpolators and a comprehensive variographic analysis module aimed at grade estimation. Standard solutions include deterministic inverse distance interpolation, masked kriging and Gaussian simulations. In addition, users gain access to domain Kriging, a unique feature designed and developed by Intrepid Geophysics. GeoModeller’s domain kriging is a generalization of transect kriging to nD curvilinear spaces. Domain kriging enables users to soft constrain the interpolation to geological units and structures while limiting confirmation bias.
