This scheme specifies concepts used to describe the method used to determine the planar or linear orientation of a GeologicFeature (eg, the dip of a fault), as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. By extension, it includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme. Designed for use in the determinationMethod property in GeoSciML GSML_PlanarOrientation and GSML_LinearOrientation elements.
