Merge Layers (Standard Feature Analysis Tools)

Summary

Copies all features from two layers into a new layer. The layers that will be combined must contain the same feature types (points, lines, or polygons). You can control how the fields from the input layers are joined and copied.

Usage

  • The inputs must be of the same feature type.

  • By default, all of the fields from both inputs will be copied to the output. Optionally, you can modify the fields from the merge layer using the Remove, Rename, or Match options of the Merging Attributes parameter.

Parameters

Label Explanation Data type

Input Layer

The point, line, or polygon features that will be merged with the merge layer.

Feature Set

Merge Layer

The point, line, or polygon features that will be merged with the input layer. The merge layer must contain the same feature type (point, line, or polygon) as the input layer.

Feature Set

Output Name

The name of the output layer that will be created on your portal.

String

Merging Attributes

(Optional)

A list of values that describe how fields from the merge layer will be modified and matched with fields in the input layer. By default, all fields from both inputs will be included in the output layer.

If a field exists in one layer but not the other, the output layer will contain both fields. The output field will contain null values for the input features that did not have the field. For example, if the input layer contains a field named TYPE but the merge layer does not contain a field named TYPE, the output will contain a TYPE field, but its values will be null for all the features copied from the merge layer.

Value table columns:

  • Merge field—Fields from the merge layer.

  • Action—How the fields from the merge layer are written to the output.

    • Remove—The merge layer field will be removed from the output layer.

    • Rename—The merge layer field will be renamed in the output.

    • Match—The merge layer field will be renamed and matched to a field from the input layer.

  • Input field—Fields from the input layer.
