Abstract
Documentation:
The corners of the triangles in the TIN are often referred to as pots. ControlPoint shall contain a set of the GM_Position used as posts for this TIN. Since each TIN contains triangles, there must be at least 3 posts. The order in which these points are given does not affect the surface that is represented. Application schemas may add information based on ordering of control points to facilitate the reconstruction of the TIN from the control points.
