Feature To Polygon
Overview
The Feature To Polygon tool extracts enclosed areas from intersecting geometries. It automatically calculates all intersections between two input feature datasets, such as lines or polygons, splits edges at the intersections, and reconstructs polygon features from the smallest closed rings formed after splitting.
How It Works
The tool reads the input vector file and the dividing vector file, runs the corresponding GIS operation, and writes the polygonized result to a new output vector file.
Use Cases
- Generate standardized polygon results from line or polygon boundaries.
- Use as an intermediate step in a longer GIS processing chain before subsequent analysis.
- Improve efficiency in batch processing, repeated execution, or standardized delivery workflows.
Parameters
| Parameter | Description | Notes |
|---|---|---|
| Input vector file | Vector file containing polygon or line features. | Required. |
| Dividing vector file | Vector file used for division. It contains polygon or line features. | Required. |
| Output vector file | Output file for the polygonized vector result. | Required. |
Steps
- Open the tool: Open the Geoprocessing Toolbox, go to Vector Tools > Feature Conversion, and open Feature To Polygon.
- Prepare inputs: Select the Input vector file and Dividing vector file according to the data type, and confirm that the input data is complete and readable.
- Set core parameters: Configure the core parameters according to the analysis goal.
- Set the output: Specify the Output vector file, and confirm that the output path, format, and naming rules meet downstream requirements.
- Run and check results: Click Run to execute the task. After completion, check whether the result extent, field structure, and spatial position are as expected.
Notes
- Before running a batch job on production data, test the parameter settings with a small sample dataset.
