Implicit 3-D modelling of geological surfaces with the Generalized Radial Basis Functions (GRBF) algorithm [electronic resource] / M.J. Hillier, E.A. de Kemp, and E.M. Schetselaar. [Ottawa] : Natural Resources Canada, Geological Survey of Canada, 2017. 15 p. : col. charts, col. ill. Geological Survey of Canada, open file ; 7814 Includes bibliographical references (p. 7). "We summarize an interpolation algorithm, which was developed to model 3D geological surfaces, and its application to modelling regional stratigraphic horizons in the Purcell basin, a study area in the SEDEX project under the Targeted Geoscience Initiative 4 program. We developed a generalized interpolation framework using Radial Basis Functions (RBF) that implicitly models 3D continuous geological surfaces from scattered multivariate structural data. The general form of the mathematical framework permits additional geologic information to be included in the interpolation in comparison to traditional interpolation methods using RBF’s such as: (1) stratigraphic data from above and below targeted horizons (2) modelled anisotropy and (3) orientation constraints (e.g. planar and linear)"--Abstract, p. 1. gccst Stratigraphy gccst Structural geology gccst Modelling Schetselaar, E.
