Overwrite a web imagery layer

In addition to publishing new web layers, you can use ArcGIS Pro to overwrite existing web imagery layers to reflect changes to a GIS resource or its source data.

You can overwrite an existing web imagery layer if all of the following conditions are true:

• You are signed in to your ArcGIS organization with the account that owns the web imagery layer being overwritten. You cannot overwrite an existing web imagery layer owned by another member of your organization.
• The location of the web imagery layer being overwritten has not changed while the Overwrite Web Layer pane is open.
• The web imagery layer is not a hosted imagery layer.

Overwriting a web imagery layer is similar to sharing a web imagery layer. You can change most of the properties of a web imagery layer when you overwrite it, including properties of the imagery and configuration settings. You can't change the name of the service or its location (the service URL).

1. Right-click the data that you want to overwrite the web imagery layer, and click Overwrite Web Layer.

   The Overwrite Web Layer dialog box appears.

2. On the Overwrite Web Layer dialog box, browse to the location of the web imagery layer in your portal, select it, and click OK.
3. Read the Overwrite Web Layer message and click OK to continue.

   Caution:

   If edits were made to the web layer, the edits will be overwritten.

   The Overwrite Web Layer pane appears. On the General tab, under Item Details, the name of the web layer is displayed. This name can't be changed.

4. Under the layer name, accept the Use the item description from the web layer default option or choose the Use the item description from the dataset option.

   The default option preserves the item description of the current web layer. The other option overwrites it.

5. Optionally, modify the information in the Summary and Tags fields. If the fields are empty, you must fill them in.

   The fields may be empty if you chose to use the item description from the dataset in the previous step.

6. Under Layer and Data Type, choose one of the following options:
   • 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.
7. Optionally, under Share with, change the settings.
   • Everyone—This option makes your content public. Anyone can access and see it.
   • My Organization—If you are signed in with an organizational account, you see this option. This option allows your content to be shared with all authenticated users in the organization.
   • Groups—You can share your content with groups to which you belong and their members.

   Leave all options unchecked if you don't want to share the item with anyone else at this time.

8. Optionally, click the Configuration tab and change settings.

   For more information, see Configure web imagery layers.

9. Under Finish Sharing, click Analyze to check for 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 the web layer. Resolving warnings is recommended but not required.

10. 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.
