The 3D surface area.

Remarks

The 3D surface area is the true area of the surface and accounts for variations in the surface elevation. The 3D area is the sum of the areas of each of the visible triangles in the surface without projecting the triangles. The greater the variation in elevations, the more the 3D area will differ from the 2D area.

An example of the difference between 2D and 3D areas is a building pad. The 2D area is the area that you can see from only the top and doesn't vary with the height of the building pad. The 3D surface area of the building pad is the sum of the areas of each face of the building pad, which would become larger the higher the building pad becomes.
