About Surface Editing Operations
Edit surfaces using data edit operations, which are added to a surface definition as edit operations and not to any of the existing surface data components.
About Minimizing Flat Areas in a Surface
When contour data is added to a TIN surface, the resulting surface can contain flat spots (triangles whose points all come from the same contour) and flat edges (triangle edges that join points from the same contour or from different contours at the same elevation).
About Smoothing Surfaces
Surface smoothing resolves a problem associated with individual contour smoothing where the smoothing is applied to individual contour lines without regard to adjacent contours, which sometimes creates overlapping contours.
About Smoothing a Surface Using the Kriging Method
Kriging is more complex than Natural Neighbor Interpolation. It requires both a model of the spatial continuity or dependence (in the form of a covariance or semivariogram), and a sample of surface data to determine the statistical trend on which to base interpolated/extrapolated points.
