The net result is that the subsequent gridding process is now using more control points which tends to constrain algorithms that may become "creative" in areas where there is little control.
Advantages: Reduces "bulls-eye" effect within inverse-distance-weighted modeling with small node spacings, restricts gridding to existing slopes, does not effect the fidelity of the gridding at the control points (unlike grid smoothing).
Disadvantages: Slows down the program, adding too many points (e.g. too many "passes") will eventually create a map/surface that is no different than a triangulation-based grid model.
Consider the following examples:
Here's a map illustrating a grid set to a maximum distance filter of 10% of the project area.
! Note: Color-contouring a grid that has been generated with the "Z=Color" option turned on requires that the user set the color scheme to the "Direct (Node Value = Color)" setting.
