Feature to Line

Overview​

The Feature to Line tool processes spatial topology between features. It identifies all intersections or overlapping boundaries between two input feature datasets (line or polygon), splits the original geometries at those contact locations, and outputs a set of independent line segment features.

Use Cases​

  • Road network topology optimization: Split road lines that physically intersect to create accurate junction nodes for route planning.
  • Utility network modeling: Split pipe or cable lines at crossings for subsequent segment flow calculation or flow direction analysis.
  • Data standardization: Convert complex intersecting polylines imported from CAD into independent GIS line features.

Parameters​

ParameterDescriptionNotes
Input feature 1The first feature dataset used in the split operation.Supports line and polygon features.
Input feature 2The second feature dataset used in the split operation.Supports line and polygon features.
Output pathFolder where the result is stored.Select a target folder.
Output file nameName of the output feature dataset.Text without a file extension.

Steps​

  1. Start the tool: Open the Geoprocessing Toolbox, go to Vector Tools > Feature Conversion, and open the Feature to Line tool pane.
  2. Set inputs: Select the input features to split in the two input boxes.
  3. Configure parameters: If needed, configure output field retention rules or reprojection options in the advanced settings.
  4. Configure output: Specify the output path and file name.
  5. Run the tool: Click Run. After processing, the generated independent line segments are loaded into the current map.

Notes​

  • Geometry validity: Make sure the input features do not contain severe self-intersection errors. iXGIS recommends running Repair Geometry before processing.
  • Attribute inheritance: Each line segment after splitting usually inherits the attributes of the original feature.
  • Coordinate system consistency: Use the same coordinate system for both datasets to obtain the most accurate split locations.
