Smooth Line
Functional Overview
The Line Smoothing tool can smooth the input vector lines. It supports 2D and 3D polylines and polygons.
Usage
Click Data Management > Vector Tools > Smooth Line
Parameters Settings
- Input Files List: Input one or more vector files. Input file format: .gpkg, .shp, *.dxf.
- Method: Multiple methods are available to smooth the vector lines.
- Mean smoothing (3\5\7 neighborhood): Use a 3\5\7 neighborhood for mean smoothing on each point of the vector line.
- Bezier (Using Line as control): Smooth using segmented Bezier curves, generating a new vector line without control points.
- Bezier (Using Point as control): Smooth using segmented Bezier curves, generating a new vector line with control points.
- B-Spline (Using Point as control): Smooth using cubic B-spline curves, generating a new vector line passing through some of the control points.
- B-Spline Fit: Fit using cubic B-spline curves, generating a new vector line without any control points.
- Output Path: Output folder path. The newly generated vector lines will be output to this folder.
