Split By Features
Function Overview
The Split By Features tool spatially cuts input features by specified split features, usually polygon features, and generates multiple independent sub-features.
This operation physically splits the original features and creates new geometry objects.
Use Cases
Administrative Boundary Data Splitting
Split a city-level road network by district or county administrative boundaries for regional traffic flow analysis, maintenance, or management.
Land Planning Management
Split a large land area by planned parcel boundaries to assign independent parcel units for different uses, such as residential, commercial, or green space.
Other Uses
- Watershed splitting: divide hydrological features by sub-watershed boundaries.
- Project zoning: divide pipeline networks by construction areas.
- Ecological zoning: divide discrete observation points by protected areas.
Parameters
Basic Settings (Required)
| Parameter | Description | Data type |
|---|---|---|
| Input features | Original features to split. | Point, line, polygon |
| Split features | Spatial boundary features used for splitting. | Polygon |
| Attribute field | Field used to split the input features and generate output feature names. | |
| Output vector folder | Storage path for the output result. | Folder path |
Notes
Coordinate System Consistency
- Ensure that the input features and split features use the same coordinate system.
- Inconsistent coordinate systems may cause incorrect split locations.
Data Quality Checks
- Geometry validity: repair invalid geometries, such as self-intersections or empty geometries.
- Topology checks: ensure the data has no overlaps or gaps, especially for boundary-based splitting scenarios.
- Field completeness: check whether key fields contain null or abnormal values.
Operating Steps
Step 1: Start The Tool
Open the Geoprocessing Toolbox, go to Analysis Tools > Extraction Analysis, and double-click Split By Features to open the tool pane.
Step 2: Set Parameters
Enter the input features, split features, attribute field, and output vector folder as prompted. All parameters are required.
Step 3: Run And Monitor The Task
Click Run to start processing. You can view progress, run time, and completion status in the task list.
If the run fails, the tool provides an error message. Use the Edit button in the lower-right corner to return to the tool pane and adjust the parameters.
