Smooth Line/Polygon
Feature Description
Performs boundary smoothing on line datasets, region datasets, and network datasets.
Feature Entry
- Data Tab->Data Processing->Vector->Smooth Line/Polygon, opens the Smooth Line/Polygon dialog.
- Toolbox->Data Processing->Vector->Smooth Line/Polygon, opens the Smooth Line/Polygon dialog.
Parameter Description
- Source Dataset: Select the dataset to be smoothed.
- Line Intersection Point Unchanged: When processing line objects, checking this option preserves intersection points between lines.
- Smoothness: Specifies the number of nodes inserted between two adjacent nodes during smoothing. This must be an integer no less than 2. The positions of inserted nodes are determined using the B-spline method. More interpolation points result in smoother polylines. Recommended value range: [2,10].
For details about the B-spline smoothing process, please refer to the Smooth Method Description document.
