Abstract
A method, apparatus, and article of manufacture provide the ability to produce a smooth triangulated irregular network (TIN) surface. A TIN surface is obtained in a drawing on a GIS/CAD application. Thereafter, a surface smoothing technique is selected, such as Kriging or natural neighbor interpolation (NNI). Once interpolation output parameters are specified, additional surface points are interpolated in accordance with the selected surface smoothing technique and interpolation output parameters. The interpolated points may then be used to smooth the TIN surface.

A method for producing a smooth triangulated irregular network (TIN) surface, comprising:
- obtaining a TIN surface in a drawing on a GIS/CAD application;
- selecting a surface smoothing technique;
- specifying interpolation output parameters;
- interpolating additional surface points in accordance with the selected surface smoothing technique and interpolation output parameters;
- and
- smoothing the TIN surface using the interpolated additional surface points.
An apparatus for producing a smooth triangulated irregular network (TIN) surface in a computer system comprising:
- (a) a computer system having a memory and a data storage device coupled thereto;
- (b) a GIS/CAD application executing on the computer, wherein the application is configured to:
- (i) obtain a TIN surface in a drawing on the GIS/CAD application;
- (ii) select a surface smoothing technique;
- (iii) specify interpolation output parameters;
- (iv) interpolate additional surface points in accordance with the selected surface smoothing technique and interpolation output parameters;
- and
- (v) smooth the TIN surface using the interpolated additional surface points.
An article of manufacture comprising a program storage medium readable by a computer and embodying one or more instructions executable by the computer to perform a method for smoothing a triangulated irregular network (TIN) surface in an GIS/CAD computer system, the method comprising:
- obtaining a TIN surface in a drawing on the GIS/CAD application;
- selecting a surface smoothing technique;
- specifying interpolation output parameters;
- interpolating additional surface points in accordance with the selected surface smoothing technique and interpolation output parameters;
- and
- smoothing the TIN surface using the interpolated additional surface points.
