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.
Use the Grid Based output location to interpolate surface points (NNI), or interpolate/extrapolate surface points (Kriging) on a grid defined within specified polygon areas selected in the drawing. After the areas are defined, the grid X and Y spacing, and orientation properties can be specified.
Use the Centroids output location to interpolate surface points (NNI and Kriging) at the existing surface triangle centroids within specified polygon areas selected in the drawing.
When this option is selected, the grid X and Y spacing and the orientation properties are disabled.
Use the Random Points output location to interpolate (NNI), or interpolate/extrapolate (Kriging) a specified number of random points within polygon areas selected in the drawing.
When this option is selected, the grid X and Y spacing and the orientation properties are disabled.
Use the Edge Midpoints output location to interpolate surface points (NNI and Kriging) at the midpoints of selected surface triangle edges in the drawing. To select the surface triangle edges, the triangles must be displayed in the drawing.
When this option is selected, the grid X and Y spacing and the orientation properties are disabled.
