Add a reference layer

When you add a reference layer to an ArcGIS Map Search map, you're providing context for the geotag and geosearch features. After you add and configure the layers, users can drag their SharePoint documents onto the map to geotag them with the location attributes you specify, and search for those documents by clicking the map. Reference layers can include layers created using data in your geocoded SharePoint lists, or they can include demographic data such as household income, age, or education. They can also include publicly shared feature layers available on ArcGIS.

For example, imagine you're an oil company worker with several wells located all over the United States. Each well has a variety of information and safety documents and related safety data sheets that provide crucial information about procedures to follow in the event of a fire or spill. You can add a reference layer that identifies the location of each well and set the geotagging attributes accordingly. Then generate geotags for all your documents by dragging them to the appropriate location on the map. Later, in the event of an emergency, users can quickly retrieve the appropriate documents by clicking the affected location on the map.

Note:

Although you can add several types of layers from ArcGIS—including feature service, map service, image service, vector tile service, KML, and WMS layers—only feature service layers and layers created from SharePoint data can be used for geotagging.

Note:

The ArcGIS Map Search app part must be in edit mode for changes to persist in the map.

Add a reference layer from SharePoint

To add a reference layer from a geocoded SharePoint list, do the following:

  1. On your ArcGIS Map Search map-enabled SharePoint page, place the page and the app part in edit mode.
  2. On the map toolbar, click Layers to open the Add layers pane.
  3. From the Add layer drop-down menu, choose From SharePoint.

    The pane lists all available content from your SharePoint site collection. Content that appears in this list has already been geocoded for use with ArcGIS Map Search. If a list doesn't appear here, check to ensure that you've correctly prepared the SharePoint list.

  4. To display items in a subsite of your site collection, click Go to site Go to site and choose the subsite. To return to the root of your site collection, click the Back button Back to root next to the subsite title.
  5. From the list of available data, click the arrow next to a list to expand its contents.

    Depending on how your list view is configured, the contents may list one or more subsets of the list, or only All items.

  6. To view information about a list item, hover over the list item and click the Details button Item details.
  7. To create the reference layer, click the radio button next to the desired list.

    You can add multiple reference layers at once.

  8. Click Add to create the reference layer.

    The reference layer appears on the map using the default display and styling options.

  9. Click Apply in the ArcGIS Map Search app part configuration pane to save your changes and continue to work with the map. If you're finished working with the page, click Page > Save on the SharePoint ribbon.

You can now set the geotag attribute for the layer or change the layer's styling and display options.

Add a reference layer from ArcGIS

To add a reference layer from ArcGIS, do the following:

  1. On your ArcGIS Map Search map-enabled SharePoint page, place the page and the app part in edit mode.
  2. On the map toolbar, click Layers to open the Add layers pane.
  3. From the Add layer drop-down menu, choose From ArcGIS.

    The ArcGIS search pane appears.

  4. Type a keyword in the Search field and press Enter to look for relevant content.

    The search results appear in the pane.

    By default, the search looks for content relevant to the currently displayed map extent. To expand the search to a broader area, switch the Within map extent toggle key off.

  5. You can filter the search results to narrow the list of displayed items.
    • Click the Filter button Filter search to display the filtering options.
    • From the Type drop-down menu, choose the specific item types to display. For example, choose Feature service to show only that type of result.
      Note:

      Although you can add any of the listed types of layers to provide context for your map, only feature service layers and layers created from SharePoint data can be used for geotagging.

    • In the Sort by section, click Relevance and choose an option by which to sort the search results. For example, choose Title to view items sorted alphabetically by item title.
    • Click the Filter button Filter search again to close the pane.
  6. Click the desired item and click Add.

    You can add multiple layers at once.

    The reference layer appears on the map using the default display and styling options.

  7. Click Apply in the ArcGIS Map Search app part configuration pane to save your changes and continue to work with the map. If you're finished working with the page, click Page > Save on the SharePoint ribbon.

You can now set the geotag attribute for the layer or change the layer's styling and display options.

Manage layers

You can manage how layers are displayed individually or all at once.

To manage layer display, do the following:

  1. To show a layer on the map, check the box next to the layer's title in the Layers pane. To hide the layer, uncheck the box.
  2. To rename a layer, double-click the layer name, type a new name in the field, and press Enter.
  3. To display the layer's symbol styling (legend), click the arrow in front of the check box.

    The layer expands to show the styling used for symbols on the layer.

  4. To manage all layers at once, do the following:
    • On the Layers pane, click the Manage layers button Manage layers.
    • Choose from the following options:
      • Turn all layers on
      • Turn all layers off
      • Expand all layers
      • Collapse all layers
  5. To change the order of layers in the Layers pane, click the Layer options button Layer options for the layer and choose Move up or Move down.
    Note:

    When you add layers from ArcGIS, feature service layers are always added to the top of the layer stack; and map service, image service, KML, and WMS layers are always added to the bottom. You can move these layers up or down, but they cannot be placed over a feature service or SharePoint layer. In this case, the Move up and Move down options will be unavailable.

  6. Click Apply in the ArcGIS Map Search app part configuration pane to save your changes and continue to work with the map. If you're finished working with the page, click Page > Save on the SharePoint ribbon.
