Manage a hosted imagery layer item and service

A hosted imagery layer (item) can be used to manage the item properties and settings for the corresponding image service. A hosted imagery layer (item) contains content properties such as name and description that describe the item resource in a portal, and data service properties such as source and URL for the map tile service and the source feature service it was derived from.

You can use the item properties to:

Update the metadata for the hosted layer such as the name, description, and terms of use.
Make an item more discoverable in a portal.
Include important terms of use or credits information.
Find data service information such as the URL endpoint.
Change the sharing and security settings.

How to manage a hosted imagery layer (item)

When you create a new data service, the hosted layer and data service sharing level (privacy setting) is set to Owner. The item and data service are only available to you. This setting requires that applications provide a valid access token to authenticate requests to view the item or to access the data service.

The steps to change the sharing properties are:

Sign in to your portal:
- ArcGIS Location Platform: Go to https://location.arcgis.com > My portal.
- ArcGIS Online: Go to https://www.arcgis.com/home/signin.html.
- ArcGIS Enterprise: Go to your portal URL. Learn more at ArcGIS Enterprise > Use > Get started > Access.
Find the item.
Use the item page to change the item properties.

Process to access and manage a hosted map tile layer (item) in a portal.

Access an item page

You can manage the properties of a hosted layer by accessing the item page in a portal. If you are the owner of the item, you can use the item page to update the properties.

https://{portal}/home/item.html?{id}

Example: https://www.arcgis.com/home/item.html?id=c7b1872373474e9086259f5796228921

Content properties

The content properties of a hosted layer (item) describe the resource in a portal. These properties uniquely define a data service and allow it to be discoverable in a portal. As an owner, you can set properties such as the name, description, tags, thumbnail, and terms of use to provide details about the underlying data service. Other properties such as id, type, created date, and updated date are read-only and are maintained by the system.

Examples of general properties include the following:

*ID: The unique identifier for the item.
*Type: The type of hosted layer.
*Item created: Date the item was created.
*Item updated: Date the item was updated.
*View count: Number of times the item page was viewed.
*Owner: Name of the owner or publisher of the data.
Name: The name of the hosted layer.
Description: Text that describes the layer, what data it contains, and what it is used for.
Terms of use: Description of usage restrictions for the data.
Tags: Search text used to find an item in a portal.
Credits: Attribution for the data.
Terms of use: The terms and usage restrictions.

*Read-only properties

Data service properties

The service properties of a hosted layer (item) provide information about the underlying data service. For example, it contains the layers, source, and service URL. These are read-only but are useful when you need to find the URL for the underlying data service and layers.

Examples of service properties include the following:

*Layers: Access to other layers if present.
*Source: The type of data service (feature service, vector tile service, map service).
*Size: The size of the data in KB.
*URL: The URL used to access the layer in the data service.

*Read-only properties

Code examples

You can use data management tools to get the properties of a hosted map tile layer (item) or you can use the ArcGIS REST APIs. The following examples illustrate how to programmatically get the properties of a hosted imagery layer (item) and image service.

Get item properties

To access the imagery layer item properties directly, use the REST API with the item ID. The example below returns the item properties and values for a tiled imagery layer (item).
