Editing Surfaces

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.
To Add Surface TIN Lines
To Delete Surface TIN or Grid Lines
To Swap Surface Triangle Edges
To Edit Surfaces by Adding Points
To Delete Surface Points
To Modify the Elevation of Surface Points
To Edit a Surface by Moving Surface Points
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 Point Interpolation/Extrapolation Output for Surface Smoothing
Choose between several options when you use either of the NNI or Kriging surface smoothing methods for the interpolation and extrapolation of the point output.
About Smoothing a Surface Using the Natural Neighbor Interpolation (NNI) Method
Use Natural Neighbor Interpolation (NNI) to estimate the elevation (Z) of an arbitrary point (p) from a set of points with known elevations.

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.
