Question

Which of the following statement about the TIN model is INCORRECT?

• A. \( \text{TIN contains irregularly spaced sampled points} \)
• B. \( \text{Triangulation is performed to form network of triangles} \)
• C. \( \text{In the TIN model, the edges represent features such as peaks and depression} \)
• D. \( \text{In the TIN model, the edges form contiguous, non-overlapping triangular facets and can be used to capture the position of linear features} \)

Hint:

Remember that TIN uses triangles to model terrain, with nodes at varying elevations and edges defining the triangular facets.

Answer 1

The Correct Option is C

In a Triangulated Irregular Network (TIN) model: \begin{itemize} \item TIN contains irregularly spaced sampled points. \item Triangulation is performed to form a network of triangles connecting these points. \item The facets (triangles), not just the edges, represent the terrain's surface and can capture the position of linear features. \item The edges of the triangles define the zonation and connectivity between the nodes, and changes in slope. Features like peaks and depressions are represented by the nodes and the overall structure of the triangular facets, not solely by the edges. \end{itemize}
