Merge Feature Classes
Overview
Merge two or more input vector datasets into one unified output dataset.
How It Works
This tool creates a new feature collection by combining features from multiple input vector files. Reliable results depend on valid geometry and consistent coordinate systems.
Use Cases
- Generate a standardized merged dataset from multiple feature classes.
- Use the merged output as an intermediate result in a longer GIS processing workflow.
- Improve efficiency in batch processing, repeated processing, or standardized delivery workflows.
Parameters
| Parameter | Description | Notes |
|---|---|---|
| First input vector file | Specifies the first input vector file. | Required |
| Second input vector file | Specifies the second input vector file. | Required |
| Output vector file | Specifies the output vector file. | Required |
| Field data merge method | Defines how fields in the new vector file are derived from the input data. Supported methods include appending fields, creating new fields, and multiple aggregation methods for field merging, such as mean, median, minimum, and maximum. |
Steps
- Start the tool: Open the Geoprocessing Toolbox > go to Vector Tools > Vector Data > start the Merge Feature Classes tool pane.
- Prepare inputs: Select First input vector file and Second input vector file according to the data type, and make sure the input data is complete and readable.
- Set the field data merge method: Configure how fields from the input files are carried over, created, or aggregated in the output feature class.
- Set the output: Specify Output vector file, and confirm that the output path, format, and naming rules meet downstream requirements.
- Run and check the result: Click Run to execute the task. After completion, check whether the result extent, value distribution, field structure, and spatial location are as expected.
Notes
- Before running batch processing on production data, validate the parameter settings with a small sample dataset.
