ET GeoWizards Toolbox
Smooth B-Spline
(Go to the main page of the
function)
Smoothes the features of a polyline dataset using a B-Spline smoothing algorithm.
Command line syntax
ET_GPSmoothBSpline <input_dataset> <out_feature class> <smoothness> <freedom>
Parameters
| Expression | Explanation |
|---|---|
| <input_dataset> | A Polyline feature class or feature layer |
| <out_feature class> | A String - the full name of the output feature class (A feature class with the same full name should not exist) |
| <smoothness> | An Integer that defines the number of points in the output curve. The allowed values ( 2 to 20 ) in fact are point multiplier. The number of vertices of the original polyline multiplied by this value will give the number of vertices of the smoothed polyline. The larger the value of the <smoothness> parameter, the slower the process will be. |
| <freedom> | An Integer that defines how close to the original polyline the curve will be. The allowed values are from 3 to 10. Smaller values give better approximation. With large values the curve will become very similar to Bezier curve |
