Surfaces
A surface, or 2-manifold, is a shape any small enough neighborhood of which is topologically equivalent to a neighborhood of a point in the plane.
Surfaces find application in physics, engineering, computer graphics, and many other disciplines, primarily when they represent the surfaces of physical objects.

Surface Creation and Analysis
With ArcGIS 3D Analyst, you can create new surfaces from existing datasets. For many applications, you may need to create a surface in order to drape other features over it.

Contouring
Contouring is covered in Raster Analysis II. In addition to creating entire contour data sets, with the 3D Analyst it is also possible to create single contours as simple graphics using the Contour tool .

The GIS deals with spatial objects or spatial phenomena which are at least 2 dimensional, but the natural features are often modeled in 3 or 4 dimension.
Sometimes the surface elevation information does not form a regular matrix, but rather comprises a collection of measured locations with altitude.
