ElevationTIN

-- Name -- elevation TIN -- Definition -- Collection of elevation spatial objects forming a particular tessellation of the space based on a Triangulated Irregular Network (TIN) according the geometry GM_Tin (defined in ISO 19107:2003). Its components are a set of control points whose elevation property values are known, and a set of break lines and stop lines. -- Description -- NOTE The TIN can be calculated using any triangulation method, which determines the spatial relationships between the spatial objects in the collection. EXAMPLE An elevation TIN model calculated by means of the Delaunay triangulation method.
