Remarks
When a TIN is initially constructed it contains four generated points that reside far outside the declared data extent. These are connected into two triangles and this initial triangulation is what the data is added to. The four generated points are referred to as super nodes. The super node extent is the minimum bounding rectangle that surrounds these points.
Example
Get Super Node Extent
var superNodeExtent = tinDataset.GetSuperNodeExtent();
