Items are the contents available in ArcGIS Online. Each item includes an item page with a variety of information, options, and settings. Browse or search the organization for items, click the item title to get a preview of what each item contains and how to use it, and open the item details page to access more information about the item.
Tip:
The information and options available to you depend on the item type, your privileges, and whether you are the item owner or administrator. Only item owners or organization administrators can configure an item's settings.
Item pages allow you to explore items in depth in a variety of ways. For example, an interactive attribute table integrates related records and attachments, allowing you to explore attribute data and view all aspects of a field together, including field values, summary statistics, and settings. Content creators and administrators can change an item's settings without having to go to other places on the site. For example, you can configure an app from a scene on the Overview tab or edit app settings directly on the Settings tab. Feature layer styles, pop-ups, and other layer properties can be configured on the Visualization tab as an alternative to opening the layer in a map viewer.
Open the item details page
To access an item page, do one of the following:
- From the gallery, click the Options button
and click View item details.Tip:
Click the thumbnail of an item to open the item details panel, which provides a quick view of an item's details. If the item contains what you need, click View item details on the item details panel to open the item details page.
- Click View details for an item.
- Click the item name on the Content page.
- Click the item name when searching for layers in a map viewer.
Sublayers in feature and table layers
Individual sublayers in a feature layer or table layer have their own details pages. These pages contain information and functionality that pertain to and affect the sublayer only. To access details for a sublayer, open the details page for the feature or table layer and click the sublayer in the Layers or Tables list on the Overview tab. To return to the details for the feature or table layer, click the layer name in the banner at the top of the details page.
You can do the following from a sublayer's details page:
- Read a summary that is specific to the sublayer.
- Read a description that is specific to the sublayer.
- Discover attribution information for the layer. It is not uncommon for each layer to have a different source or origin.
- Copy the URL for the sublayer so you can reference the individual sublayer in another app.
- Open the sublayer in Map Viewer or Map Viewer Classic.
- Access each sublayer's metadata.
- View each sublayer's attribute data.
- Visualize the sublayer.
- If the item is a hosted feature layer and the layer owner or an administrator enables exporting, you can export the sublayer's data to another format.
View overview information
The Overview tab includes a summary of information about an item that explains what the item contains. Use the overview information described below to better understand the item before you use it.
Title
The title is the item name that is shown when you access the item. The title reflects what the item contains.
Summary
The summary is a short description of the item.
Item status
Organization administrators can indicate what items are the authoritative version of a particular set of data, a map, a scene, or an app. When an item is designated authoritative, an authoritative badge is shown near the top of the item's Overview tab.
For example, if the organization contains several layers representing roads, an administrator can identify the layer that is the most complete and accurate, and designate it as the authoritative layer.
When an item is outdated or is no longer needed, an administrator or the item owner can designate the item as deprecated. If that is the case, the deprecation label displays near the top of the item's Overview tab. The deprecation badge acts as a warning that the item may soon be deleted. It indicates that you should not use this item and, if you are using it, provides you time to find a replacement.
Tip:
Authoritative and deprecated badges also appear on the item on the Content page or search results. You can also use the status filter on the Content page to identify authoritative and deprecated items.
Developer information
Apps that are registered with the OAuth 2.0 credential, token, and redirect information appear with an OAuth 2.0 Application badge. This badge indicates to developers that they can use the information in the app item to allow users of the app to authenticate using their ArcGIS Online credentials.
Description
The description provides in-depth information about the item.
Thumbnail image
The thumbnail image provides a visual representation of the item.
For layers, maps, and scenes, this is usually a preview of the item's content. However, the item owner or organization administrators can change the thumbnail image. For example, items related to the same project might include a thumbnail image that represents that project. For file-based items, the owner could add a thumbnail image that indicates the type of file it is or the type of information the file contains.
The thumbnail appears on the item details page as well as the Content page when you view items in a list or grid.
Terms of Use
This section provides information about how the item can be used and by whom. For example, if you must display copyright information or credits to the source agency for a web map you use in a report or article, that information will be stated in the item's Terms of Use field.
Metadata
Metadata provides even more in-depth information about an item. If the item has metadata defined, you can click the Metadata button to view the item's metadata in the metadata style configured for the organization.
Individual layers in a multilayer feature layer can store metadata that is different than what is set for the feature layer. To access the metadata for a sublayer, click the sublayer in the Layers section on the feature layer's Overview tab.
Item ID
Every item in ArcGIS Online is assigned a unique identifier (ID). This ID is part of the item's URL and is also available in the Details section of the Overview tab on the item details page.
Every item in your organization is assigned a unique identifier (ID). This ID is part of the item's URL and is also available in the Details section of the Overview tab on the item details page.
Developers who need to reference an item in their custom apps use the ID to ensure they access the correct item. They can copy the ID from the Details section to paste into code.
For examples of using an item's ID, see the following developer pages:
Image properties
If the item is a hosted imagery layer, the details and image properties are listed on the item page. Details include the size and image count of the imagery layer. Image properties include the source type, pixel type, number of bands, and cell size.
Level of sharing
Items are labeled to indicate who has access to them—the public, all organization members, members of specific groups, or only the item owner.
Ensure that the item is configured for the appropriate level of sharing before you use an item, send someone the URL for an item, or share the item on social media. For example, you cannot share an item to Twitter if the item is not shared with the public. Similarly, if an item is shared with a group and you send the item's URL to people who are not members of that group, they won't be able to access the item.
The level at which the item is shared is visible under Share on the item's Overview tab, and also on the item in the Content page.
Credits (Attribution)
Attributions for the individual or agency who provided the data let you know where the data originated.
Attributions for layer items appear at the bottom of the map when you add the layer item to Map Viewer.
When attributions are set on the sublayers in a multilayer feature layer, the sublayer attributions appear in Map Viewer when you add the layer to a map.
Tags
Tags are added to items by the item owner or organization administrator to help people find the items when they initiate a search. In most cases, you won't read the tags on the item detail page unless you need to comment on the keyword tags that you expected for the item, and thereby help the item owner improve search results for the item.
Feature and table layer details
Feature layers and table layers include a Data tab in their item details. You can view the attribute table for the layer on the Data tab using either of the following options:
- Table—When you view the attribute table using this option, all the fields (columns) and rows in the table, the fields and rows in related tables, and all the attribute data are shown. This view of the table is best when you want to view, sort, or edit or delete the attribute data stored in the table and when you want to view and add attachments, such as related photos or other files. Layer owners, organization administrators, data curators, and members of shared update groups can edit or delete attribute data.
You can also learn more about the individual fields—for example, determine whether a field is required or view its default value—by clicking the column header of the field and clicking Show Detailed View. The table is reduced in size to a more focused view of the field you selected, with a Summary section; a Settings section with field attribute rules, such as required fields and default value; and a Details section with information such as the field name and type. The information available in each section depends on the field type and your privileges. For example, in the Summary section, a histogram is shown for numeric fields, or a list of the top 10 unique values and associated count information are shown for text fields.
To choose a different field to explore without returning to the full table, click the Options button
and select a different field. After you finish viewing detailed information about a field, you can return to the full table view by clicking the Close button. - Fields—When you view the table from the Fields page, a list of all the fields in the attribute table is shown, including hidden fields and fields from related tables. You can filter for specific data types and change the list order of the fields on the Fields page by clicking the Sort by button. For more information about a particular field, click the field's Display Name setting.
If the layer owner or administrator defined a description or type for each field, this information displays on the Data tab. This helps you determine how to represent the fields in your maps and what information is required when you edit attributes in the layer.
Note:
For feature layers that contain multiple layers, you can work with the attributes and fields of the individual layers by first selecting the layer from the Layer drop-down menu. If you click the Data tab on the details page of an individual sublayer, the Layer drop-down menu is not available. All changes you make on a sublayer's Data tab apply only to that sublayer, and you cannot switch between sublayers.
View attributes
Attribute data for a feature layer item can be viewed in the attribute table. Do either of the following to view attributes:
- To make it easier to view attribute data, sort the attributes by clicking the column header and selecting Sort Ascending or Sort Descending.
Note:
Some older versions of ArcGIS Server may not support sorting.
- To hide or show attribute fields, click the Show/Hide Column button at the top of the table. Check the boxes to show attribute columns. Uncheck the boxes to hide them.
Tip:
If the layer is an editable hosted feature layer, data curators and members of shared access groups can edit or delete attributes. To edit an attribute in the table, select the value in the cell, type a new value (or remove the value if you want to delete it), and press Enter to save your changes.
Options that allow you to interact with the item
If, after reading the item information, you determine the item meets your needs, you can use options on the Overview tab to do the following:
- Open or download the item. (Options to open the item are also present on the details preview panel.)
- Add the item to a list of your favorites. (The option to add the item to your list of favorites is also available on the details preview panel.)
- Add a rating or comment to the item.
- Copy the source URL for items that have them, such as web services or web apps.
- Share the item's details page using a short URL.
- Share the item to social media sites.
Some types of item pages have additional options. For example, you can explore and change how you visualize feature layers, publish apps from the item page of configurable apps, create an app from a web map or web scene, export data from export-enabled hosted feature layers, or copy the WMTS endpoint for a hosted tile layer.
Open or download items
The action buttons available on the Overview tab of the item page or the preview panel depend on the item type.
By default, items open in the most appropriate app. For example, maps open in Map Viewer or Map Viewer Classic, scenes open in Scene Viewer, and layer packages open in ArcGIS Pro. Sometimes other options are available. For example, you may be able to open a map in ArcGIS Pro instead of Map Viewer.
You can open the sublayers of a feature layer in Map Viewer or Map Viewer Classic only.
Note:
The option to open a feature layer in Map Viewer Classic is not present if the feature layer contains data that is not supported in Map Viewer Classic.
Some items, such as files, can be downloaded. Once you save the file to your local machine, you can open it in the appropriate software.
Maintain a list of favorite items
You can create a list of favorite items to make it easy to access items you use frequently.
You can add an item to your favorite items list from the My content, My groups, My organization, or Living Atlas tabs of the Content page using one of the following methods:
- Click the Options button for the item and click Add to favorites.
- Click the item's title to open the item preview panel, and click Add to favorites on the panel.
You can view the list of items from the My favorites tab on the content page and when you search for layers to add to a map.
Remove a favorite item from the list by opening the My favorites tab of the Content page and doing one of the following:
- Click the Options button for the item and click Remove from favorites.
- Click the item's title to open a pane containing information about the item, and click Remove from favorites in that pane.
Add ratings and comments
Ratings and comments can help content creators and other users assess the usefulness of an item.
Each item page includes a rating. Ratings are based on a weighted average of five stars, with one star indicating a poor item and five stars indicating a great item. The rating value provides a weighted average that factors in the number of ratings an item has received as well as the average rating. For example, an item with two ratings of four stars each has a higher rating than an item with one rating of four stars. To rate an item, you must be signed in and can only rate items you don't own. You can only add one rating per item. While you can change your rating, the count remains the same. To rate an item, click the appropriate star in the Details area on the side of the Overview tab.
Item pages can also include a section for comments, depending on whether your organization enables them. Comments appear at the bottom of the Overview tab and can be added by the item owner or other signed-in users. Once you publish a comment, you can delete it, but you can’t edit it. People who are signed in can also reply to a comment. Item owners receive email notifications of new comments and can delete comments published for items they own. Use the Sort by option to sort comments from newest to oldest (New) or by most recent reply (Latest Reply). You can subscribe to an RSS feed of comments for an item that is shared with everyone (public). You cannot subscribe to comments for an item that is only shared with your organization (or that is private).
Copy the URL
You can copy and paste the URL of an app, ArcGIS Server layer, or hosted layer and use it elsewhere. For example, developers can include the URL of a hosted web layer in apps they build.
For image items that are shared with the public (everyone), the URL field can also be used to include the image in pop-ups.
Share an item page using a short URL
To share an item page by providing a link to the page, use the Short URL button 
in the Details section. Clicking the Short URL button generates a short URL for the item page that you can copy and paste into emails, text messages, and other communications. You can share the item page short URL for any item
on the website, including those owned by others. However, before sharing the short URL, ensure that the item has been shared
with the recipients of the link; otherwise, some people may not have access to the URL.
For example, if you provide the short URL to individuals inside and outside your organization but the item has only been shared with the organization, those who are outside the organization cannot access the item.
Share an item page through Facebook or Twitter
If your organization allows sharing outside the organization and you have privileges to share with the public, the item page includes a Facebook button 
and a Twitter button 
. Use the buttons to share an item page through your
Facebook and Twitter accounts. You can share the item page of any item
on the website, including those owned by others. It's a good idea to
share only pages for items that you know are shared
with everyone; otherwise, some people may not be
able to access the links.
When you use the Facebook and Twitter buttons on an item page, you are sharing the item page, not the item. To share a map (as opposed to its item page), use
the Share button
on the map.
Explore feature layers
The item details of feature layers include a Visualization tab. On the Visualization tab, you can make changes to the default properties of a feature layer without opening the layer in a map viewer. You can change the layer’s style, apply a filter, configure pop-ups, or label the features in the layer. You can also hide the layer in the legend or change the refresh interval. As in Map Viewer, the Visualization tab provides tools to explore the layer and access the basemap gallery, as well as a search box to find an address or place.
If you own the item, you can save changes you make to the layer. Changes to the layer properties are saved to the existing layer item.
Both the item owner and those who have privileges to create content can also save a copy of the layer as a new item. The new item references the original source layer but appears on the My content page of the member who creates the copy. You can save copies of layers as items in Map Viewer or on the Visualization tab of the layer item's details page.
Some of the properties you can configure on the Visualization tab are listed below.
Note:
If the feature layer contains multiple layers, use the Layer drop-down menu to select a sublayer. If you click the Visualization tab on the sublayer's details page, the Layer drop-down menu is not available; all the changes you make are automatically applied to the sublayer.
- Change the style
- Apply filters
- Configure pop-ups
- Configure labels
- Set layer refresh interval
- Search locations and features
- Navigate the map
- Choose a basemap
- Save changes to a layer and save a layer as a new item. This option is available for item owners, administrators, or shared update group members.
