The Merge Layers tool
copies two layers to create a single output
layer. Both layers must have the same geometry
type (tabular, point, line, or polygon) and the same schema. If
time is enabled on one layer, the other layer must also be time
enabled and have the same time type (instant or interval).
Workflow diagram
Example
The City of Los Angeles wants to restore the area around the Los Angeles River by developing a new park. The park must be near the Los Angeles River but not in close proximity to existing parks or toxic release facilities. Buffers around the existing parks and toxic release facilities can be merged into a single layer using the Merge Layers tool to create an exclusion zone where a new park cannot be developed.
Usage notes
- Two inputs of the same feature type are required (point, line, polygon, or tabular).
- The two inputs must have the same schema to be merged.
- The Merge Layers tool can merge inputs with the same schema that have fields in a different order. However, it is a best practice to only merge inputs with fields in the same order.
Parameters
| Parameter | Description | Data type |
|---|---|---|
Input Layer | The point features for which density will be calculated. | Features |
Merge With | The point, line, or polygon features or table to merge with the input layer. The merge layer must contain the same feature type and schema as the input layer. | Features |
Output layer
The output layer will retain the same schema of the input and merge layers.
Considerations and limitations
- Input layers can be point, line, or area features, and both must be the same feature type.
- Input layers must have the same schema.
- When merging fields with the same name but different nullable values (nullable can be true or false), the resulting field will be nullable.
