Share a map image layer—ArcGIS Pro

With ArcGIS Pro, you can share a map image layer to your ArcGIS Enterprise portal. A map image layer is a type of web layer that can include both feature and non-feature layers as sublayers. All sublayers in a map image layer can be visualized; feature sublayers can be queried. Map image layers can be configured to draw dynamically from data or from new or existing cached tiles.

Map image layers do not support web-based editing; however, you can optionally share an editable feature layer when you share the map image layer.

The map image layer type is available only if you are sharing to an ArcGIS Enterprise portal. You must also have the privilege to publish server-based layers.

When you prepare map layers in ArcGIS Pro to share as a map image layer, follow the guidelines in Author a multiscaled map for optimal performance. Maps created in ArcGIS Desktop and imported to ArcGIS Pro must also follow these guidelines.

While in the process of sharing a map image layer, you may decide to save a service definition instead. A service definition compiles information into a single file, allowing you to share the map image layer at a later time. Information about saving a service definition is included in the workflow below. To learn more, see Introduction to saving service definitions.

You can also use ArcPy to share a map image layer to a portal. To learn more, see Automate sharing web layers.

Share a map image layer using the default configuration

This workflow explains how to share a map image layer using default settings. To change the default configuration, see Configure a map image layer.

To share a map image layer, do one of the following:
- Share all usable layers in the map as a web layer. On the Share tab, in the Share As group, click the Web Layer drop-down arrow, and click Publish Web Layer .
- Share selected layers in the map or scene as a web layer. Select the layers in the Contents pane, right-click any selected layer, point to Sharing, and click Share As Web Layer .
The Share As Web Layer pane appears.
Provide a name for the web layer.
Optionally, complete the Summary and Tags fields.
A summary and tags are required when sharing to an ArcGIS Enterprise 10.9 or earlier portal.
You can enter a maximum of 128 tags.
Under Data and Layer Type, click Map Image under one of the two data types:
- Reference registered data—Data that is registered with the server is referenced rather than copied to the server.
- Copy all data—All data is copied to the server.
  If you are sharing a catalog, line, or polygon layer in the 3D Layers category of a scene, the Map Image option does not appear under Copy all data.
For more information, see Understanding reference registered data and copy all data.
If you click Map Image under Reference registered data optionally check the Feature check box to share a web feature layer in addition to the map image layer.
If you are sharing a catalog, line, or polygon layer in the 3D Layers category of a scene, a web feature layer is automatically included.
Note:
If you share a feature layer in addition to the map image layer, see Share a web feature layer for information about configuring its properties.
Under Location, use the Portal Folder menu to choose a folder in your portal content in which to store the web layer. Optionally, create a folder.
By default, the web layer is stored at the root level of your portal content.
Tip:
Click the Browse button to browse to a folder in your portal content. You can also type a folder name in the text box.
Use the Server and Folder drop-down menus to specify the federated server where the service is published and the folder where it is stored. Optionally, create a folder.
By default, the service is stored in the root folder of the server.
Note:
You can click the Data Stores button to open the Manage Registered Data Stores pane. Use this pane to register geodatabases and folders with federated servers.
Under Sharing Level, specify how the web layer will be shared:
- Owner—Only the owner (and organization members with privileges to view content owned by other members) can access the item. This is the default option.
- Organization—Share your content with all authenticated users in your organization. This option is available when you are signed in with an organizational account.
- Everyone (public)—Share your content with the public. Anyone can access and see it.
1. Optionally, under Groups, select groups to which you belong to share your content with their members.
Optionally, click the Content tab to view the folder, new web layers, and sublayers with assigned IDs if available.
If you enabled the Allow assignment of unique numeric IDs for sharing web layers option on the Map Properties dialog box, assigned IDs appear for each sublayer. To change an ID, click the number next to the layer or table. On the Layer Properties or Standalone Table Properties dialog box, on the General tab, type a custom integer ID in the Layer ID or Table ID text box. For more information, see Assign layer IDs.
Under Finish Sharing, click Analyze to review for potential problems.
Errors and warnings are listed on the Messages tab. Right-click a message to open its help topic or take corrective action in the software. Errors must be resolved before you can share your GIS resource. Resolving warnings is recommended but not required.
Learn more about analyzing GIS resources
After you have resolved errors, and optionally, resolved warnings, click Publish to share the web layer.
To save a service definition for the web layer instead, click the Publish drop-down arrow and click Save As SD. To learn more, see Save a service definition for a web layer.
When the web layer is successfully published, click the Manage the web layer link at the bottom of the pane to access the web layer in your portal.
If the web layer will be drawn from cache built automatically on the server, the web layer may not be viewable while cache generation is in progress. Click Jobs to view the cache status in the Job Status pane.

Considerations when sharing to older portals

Map image layers can be shared to earlier versions of ArcGIS Enterprise and Portal for ArcGIS, starting with Portal for ArcGIS 10.4. However, not all functionality is supported by earlier versions. Limitations are listed below.

ArcGIS Enterprise 11.2 and earlier

Sharing subtype group tables is not supported.

ArcGIS Enterprise 11.1 and earlier

Sharing oriented imagery layers or catalog layers is not supported.

ArcGIS Enterprise 11.0 and earlier

The network analysis capability is not available for network dataset layers.

ArcGIS Enterprise 10.9.1 and earlier

The OGC Features layer is not available.

ArcGIS Enterprise 10.9 and earlier
