A surface created using the TIN algorithm for calculating earthwork volumes is called a:

• A. Elevation Surface
• B. DEM Surface
• C. Grid Surface
• D. TIN Volume Surface

Answer: (D)

Modeling earthwork volumes relies on a surface that represents the volume between the existing ground and the proposed design. A TIN Volume Surface uses the same triangulated irregular network approach to model that difference, triangle by triangle, so you can calculate cut and fill accurately. It’s built specifically for volumes, not just elevations. Elevation Surface, DEM Surface, and Grid Surface all represent elevations directly, but they don’t model the volumetric difference between surfaces. So the surface created with the TIN algorithm for calculating earthwork volumes is the TIN Volume Surface.
