Members of the default administrator role or custom roles with the appropriate administrative privileges can choose which basemaps, configurable apps, and analysis layers your organization uses to create maps, scenes, and apps, and to perform analysis. You can also set the default basemap, extent, and units and include a Bing Maps key to allow your organization to use Bing Maps.
- Verify that you are signed in as a member of the default administrator role or custom role with administrative privileges to manage the organization website.
- At the top of the site, click Organization and click the Settings tab.
- Click Map and scene on the side of the page.
- Configure any of the following map settings:
Tip:
Group owners can add public items to their groups. This means that as a group owner, you can include basemaps and app templates shared to ArcGIS Online by Esri in your customized basemap and configurable apps galleries. For example, you can include the World Transportation layer in the basemap gallery.
Primary map viewer
Members of your organization have access to two map viewers included with ArcGIS Online: Map Viewer and Map Viewer Classic. Select the primary map viewer for your organization to use when working with maps and layers. The map viewer you specify will open by default when members click the Map link at the top of the website or open maps and supported layers from content or item pages.
Note:
Individual organization members can set a different primary map viewer from their user settings. Both Map Viewer and Map Viewer Classic are available from the app launcher regardless of the primary map viewer specified.
Basemap gallery for maps and scenes
To specify the basemap gallery used in Map Viewer and Map Viewer Classic, under 2D Group, click the Edit button 
to open the Group drop-down menu and select the group that contains the maps that will be used as basemaps:
- Choose Esri Default to use only Esri default vector basemaps.
- Specify a custom basemap gallery group in your organization to include basemaps shared with it.
If you specified a custom basemap gallery group, you can click Share basemaps to share the Esri default basemaps with the group. You can also change how the basemaps are sorted in the gallery by selecting a field and a sort option from the drop-down menus under Sort order. If you change the sort field or order here, the items on the group page, as well as in embedded galleries or gallery apps, are also changed.
To check for new basemaps or remove deprecated maps from your organization's custom basemap gallery, click Update basemaps. Use the options in the Action drop-down menus to remove or add basemaps and click Save updates. You can also use the filters to narrow the basemap list or click the name of the basemap owner to access more information.
To specify the basemap gallery used in Scene Viewer, under 3D Group, click the Edit button to open the Group drop-down menu and select the group that contains the web scenes that will be used as basemaps:
- Choose Esri Default to use only Esri default vector basemaps.
- Specify a custom basemap gallery group in your organization to include basemaps shared with it.
Note:
You can specify a different basemap gallery for Map Viewer and Map Viewer Classic than for Scene Viewer. The Scene Viewer basemap gallery only displays basemaps that are supported in Scene Viewer.
Custom 3D basemaps are not supported in Scene Viewer. The 3D Group section can be used to select a subset of 3D basemaps provided by Esri for use with Scene Viewer.
By default, 3D basemaps provided by Esri are available and can be used in web scenes. To hide these basemaps from users, turn off the Use 3D basemaps toggle button in the 3D Group section.
Map and scene defaults
If you chose a custom 2D basemap group for the Basemap gallery setting, choose a basemap from that group that you want opened when users create a map with Map Viewer or Map Viewer Classic. Similarly, if you chose a custom 3D basemap group for the Basemap gallery setting, choose a basemap from that group that you want opened when users create a scene with Scene Viewer. If you chose Esri Default as the basemap gallery (for both maps and scenes), the default Esri basemap will be displayed for new maps and scenes. If you chose None for the default 3D basemap, the default 2D basemap will be used in new scenes.
Note:
Scene Viewer only uses the specified default basemap if it is a supported web scene.
The default basemap opens at the default extent you set. To set the default extent to the extent of your currently selected default basemap, click Use map extent as default. To set a different extent, click Choose extent in the Default extent section. Choose from the following options:
- To create an extent based on the default extent specified for the organization, click Organization's extent.
- To create an extent based on the region specified for the organization, click Organization's region.
- To navigate to a place or address, under Use location search, type keywords in the search box. Keywords can include addresses, street intersections, places, points of interest, and longitude and latitude coordinates. The extent centers on the place or address you specify.
- To draw a shape representing the extent, click Draw Extent and drag a box on the map. Make changes to the extent as needed by dragging any of the vertices of the extent box or clicking inside the box and dragging it to a new location.
- To create an extent by specifying coordinate values (in decimal degrees) for the extent boundaries, click Coordinates and type the coordinates in the Top, Bottom, Left, and Right boxes.
Once you have set the extent, click Save.
Under Units, choose US Standard or Metric as the default units for the map scale bar, measure tool, directions, and analysis. US Standard sets the units to miles, feet, and inches; Metric sets the units to kilometers, meters, and centimeters. Members can set the units they see through their settings page.
Bing Maps
If your organization wants to use Bing Maps in maps, enter the Bing Maps key that Microsoft provided you.
If you enable this option, members of your organization see Bing Maps as an option for adding layers from the web in Map Viewer Classic.
Check the box to allow your Bing Maps key to be used in maps shared publicly by organization members (your Bing Maps key is exposed to the public). This option only appears if your organization allows anonymous access to your site (in the Security section). If you disable anonymous access, the public can no longer see your maps with Bing Maps. To reenable public access to your maps with Bing Maps, check the option to allow anonymous access and check the option to allow your Bing Maps key to be used in maps that are shared publicly.
If you have questions about using Bing Maps with ArcGIS Online, contact your account manager or local Esri office.
Configurable apps
Choose a group that contains the app templates you want to show in the apps gallery when members choose Configurable Apps to create an app.
Choose Esri Default to use the current Esri default configurable apps for your language. Alternatively, you can choose a different group from the group list.
If you select a group other than the default, you can configure the following options:
- Change how the apps are sorted in the gallery by selecting a field from the Sort order list and choosing Ascending or Descending. If you change the sort field or order here, the items on the group page are also changed.
- Include Esri default apps in the gallery with your group items by clicking Share the Esri default configurable apps with group. You can also add other Esri public configurable apps not included in the default set (for example, retired apps) by sharing items with your group. (To remove configurable apps, open the group and remove the items you no longer want to appear in the apps gallery.)
- Add more Esri default apps (for example, after a site update) by clicking Share the Esri default configurable apps with group.
Note:
Each app template in your group must include a downloadable .zip file containing its source code and a preview version that can be displayed in a web browser. Add the preview version as a Web Mapping Application item and attach your source code to the item.
Include web styles
Web styles are collections of symbols created in ArcGIS Pro and stored as items. Apps such as Map Viewer and Scene Viewer can use web styles to symbolize features with 2D or 3D symbols.
To include web styles in Map Viewer symbol galleries or in Scene Viewer, do the following:
- Create one or more groups.
- Share the web style items with the group or groups you created.
Note:
If you are using the group to include 2D web styles in Map Viewer symbol galleries, you must also share the web style items with the public.
- At the top of the site, click Organization and click the Settings tab.
Note:
You must be signed in as a default administrator or custom role with administrative privileges to manage the organization website.
- Click Map on the side of the page.
- Do either of the following:
- For 2D web styles, click the box under 2D web style group and choose the group you created for the 2D web styles.
- For 2D sketch web styles, click the box under 2D sketch web style group and choose the group you created for the 2D sketch web styles.
- For 3D web styles, click the box under 3D web style group and choose the group you created for the 3D web styles.
The web style items in the specified group are added to the symbol galleries.
Analysis layers
Note:
This functionality is only supported in Map Viewer Classic.
Choose a group with the layers you want used in the Analysis layers gallery. Layers added to this group must include a tag that indicates their geometry type—point, line, or polygon. The analysis tools use this tag to determine the appropriate layer type. Currently, only feature items that contain a single layer are supported in the analysis gallery. Any other item types in the group, including feature layers with multiple layers, will not be displayed in the gallery.
To change how the layers are sorted in the gallery, select a field from the Sort order list. To change how the layers are ordered, choose either Ascending or Descending. If you change the sort field or order here, the items on the group page, as well as in the gallery, are also changed.
