What is the difference between Area and Surface area


Area is 2D area looking down. Surface area is 3D area of surface inside region.

Area is the 2d plane. Surface area is a 3d measurement that includes the elevation changes which is why it is always larger. Basically a 3d surface is a bunch of triangles that connect the points from the point cloud together and a surface area is the sum of all the areas from those individual triangles.
