HOW TO

Create a new feature layer from selected features in ArcGIS Online Map Viewer Classic

Last Published: July 27, 2023

Summary

When editing a web map in ArcGIS Online Map Viewer, it is useful to create a new feature layer based on feature selections, instead of creating a new layer and adding desired features in it. This article explains how to select features based on the desired attributes or spatial queries using the Find Existing Locations or Derive New Locations tool, after which a new layer is generated as the output.

Note:
The Find Existing Locations and Derive New Locations tools perform similar functions as the Select Layer by Attribute and Select Layer by Location tools in ArcGIS Pro.

Procedure

The following workflow is applicable to both the Find Existing Locations and Derive New Locations tools.

Note: 
Both tools perform similar functions; the main difference being the Derive New Locations tool can contain partial features. Refer to ArcGIS Online: Map Viewer analysis tools for more information.
Warning:   
In ArcGIS Online, using analysis tools in Map Viewer consumes credits, depending on the number of records and the generated output. Click 'Show credits' before running an analysis to check credit costs. Refer to ArcGIS Online: Understand credits for more information.
