ArcGIS Online and the developer dashboard provide content management tools to manage hosted layers and data services. These tools allow you to administer hosted layers through item pages. You use item pages to set hosted layer properties, set data service capabilities, and perform other maintenance operations such as caching, data uploading, exporting, and publishing.
Here are some operations you can perform with item pages:
- Set the item name, description, and tags.
- Set sharing properties.
- View data.
- Build indexes and caches.
- Optimize drawing and visibility levels.
- Set visualization properties.
- Set editing and edit tracking properties (hosted feature layer).
- Upload and replace data (hosted feature layer).
- Create views (hosted feature layer).
- Export data (hosted feature layer).
- Set offline capabilities.
- Publish new layers.
When you use data management tools to create a new hosted layer, a new item and layer in a data service are created. The item is assigned a unique ID and stored in your account. An item contains properties for the hosted layer such as the name, description, ID, URL, sharing settings, and data service (source). You use the item page to manage and update the properties and capabilities of your hosted layers.
You can access hosted layers with tools in ArcGIS Online and the developer dashboard.
To access hosted layers that you own, you need to sign in to ArcGIS Online or your developer dashboard. This gives you access to items in your account.
If you know the ID for a hosted layer, you can access the item page directly with a URL.
If the item is is private, you will be prompted to sign in and redirected to the item ID URL:
If you would like to search for all hosted layers that are public, you can do so using ArcGIS Online.
Item pages provide a number of settings through which you can manage your hosted layers. The available (visible) settings depend upon the type of hosted layer the item page represents, and also whether it is the owner or another user viewing the item page. Only the owner of an item can change its settings through the item page. If an item is private, it is only accessible to the owner; if it is public, others can search for and find those items on ArcGIS Online.
The following is a list of the primary settings available in an item page for most hosted layers:
- Name: The name of the hosted layer.
- Description: Text that describes the layer, what data it contains, and what it is used for.
- Type: The type of hosted layer. e.g. Feature layer or Tile layer
- Layers: Access to other layers if present.
- Tags: Search text used to find item in ArcGIS Online.
- *Owner: Name of the owner or publisher of the data.
- *Source: The type of data service.
- *URL: The URL used to access the layer in the data service.
- *ID: The unique identifier for the hosted layer.
*Read-only properties that are assigned when the hosted layers are created.
You can update and change these properties as necessary. Properties such as the Owner and URL are defined by ArcGIS Online when a hosted layer is created.
If you are viewing the item page in ArcGIS Online, properties are organized into the following tabs: Data, Visualization, Usage, and Settings.
The most common property to set in an item page for a hosted layer is the sharing property. When a hosted layer is created, the Sharing property (privacy setting) is set to Owner. This setting requires that applications use an API key or some other mode of authentication to access that hosted layer. Learn more about authentication in Security and Authentication.
The following is a list of available sharing options:
- Owner: Only the owner has access.
- Organization: All members of your organization can access.
- Everyone (public): Anyone can view and access.
To set the sharing property, use the Share button on your item page.
