By default, no specific set of analysis layers are configured for the portal. As the portal administrator, you can guide portal members to a specific group of layers you have decided are appropriate for use in standard feature, raster, and GeoAnalytics Toolsin the map viewer by setting the map viewer's Analysis Layers group.
You can choose one group as the portal's Analysis Layers group.
If your portal is configured to access Living Atlas of the World subscriber content, you can make the Living Atlas Analysis Layers available to your portal members from analysis tools in the map viewer.
Layers in the Living Atlas Analysis Layers group are optimized for analysis, but they access layers in ArcGIS Online. Your portal must have access to the Internet and be configured to access Living Atlas subscriber content to use content in this group. Note that because analysis on these layers runs remotely from the portal, performance times may be slower than when run on local layers.
As an alternative, you can create a group and share feature layers to it that your portal members will use most frequently in analysis workflows. You can share content from different sources to this group. For example, you could include feature layers hosted on the portal, feature layers from a federated server, and feature layers from Living Atlas. Just be sure that the feature layers you share to this group contain a single layer. If you place multilayer feature layers in the Analysis Layers group, analysis will always run on the first layer when portal members access the feature layer through the Analysis Layers group in the map viewer.
Decide which group to use for analysis layers
You can configure the portal to access Living Atlas subscriber content, which gives your portal members access to existing layers from ArcGIS Online. These layers are shared to a group named Living Atlas Analysis Layers in your portal. If these layers meet your analysis needs, you can configure the map viewer to use the Living Atlas Analysis Layers group for Analysis Layers.
If any of the following conditions exist, create your own group and share feature layers to it for analysis:
- You do not have access to Living Atlas subscriber content, but you do want to specify a group Analysis Layers.
- You have access to Living Atlas content, but you want to include layers from your portal along with Living Atlas layers for analysis.
- You only want portal members to perform analysis on local layers.
Specify the Analysis Layers group
Follow these steps to configure a group of layers for portal members to use in analysis tools in the map viewer:
- Sign in to the portal website as a member of the default administrator role.
- If you want to use Living Atlas subscriber content for analysis, follow the steps to enable access to this content in your portal.
- If you want to use a group you define, create a group with the following settings:
- Set the group's Status to Organization. This allows portal members access to the group.
- If you want the group to only contain the content you designate, set the group's Contributors property to Only group owner. This allows you to control what content is shared to the group.
- If you created your own group, share the layers you want used for analysis with the group and your portal organization.
You can include individual Living Atlas layers in your own group by sharing them with your group. However, do not remove any of these Living Atlas layers from the Living Atlas or Living Atlas Analysis Layers groups, or remove sharing on these items from your portal organization.
- Set the Analysis Layers group for the map viewer.
- Open My Organization > Edit Settings > Map.
- Scroll to the Analysis Layers section and choose the group to use for analysis tools in the map viewer.
- If you configured Living Atlas subscriber content to use for analysis, choose Living Atlas Analysis Layers from the drop-down list.
- If you configured your own group of content for analysis, choose your group's name from the drop-down list.
- To change how the layers are sorted, select a field in the drop-down list next to Sorted by. To change how the layers are ordered, check or uncheck the box next to Ascending. If you change the sort field or order here, the items on the group page, as well as in the gallery, are also changed.
- Click Save to apply your changes.
