Add a knowledge graph to a map

You can add entities with a spatial location to a map. This allows you to visualize spatial relationships between entities that are not apparent in a nongeographic view.

When you add entities and relationships to a map, a knowledge graph layer is created in the Map Contents pane (number 1 in the image below). A knowledge graph layer is a composite layer with a knowledge graph as its data source. The knowledge graph layer contains knowledge graph feature sublayers and knowledge graph table sublayers. Knowledge graph feature sublayers provide access to entity and relationship types in which their instances can have spatial features. Knowledge graph table sublayers provide access to nonspatial entity and relationship types.

You can create a blank map in the Investigation Contents pane or you can start from any of the views in which you work with a knowledge graph: link charts, the knowledge graph view, data cards, global search, and other maps. You can select entities and relationships in the active view and add them to a new map. After adding content from a knowledge graph to a map, use the context toolbar (number 2 in the image above) to work with graph layers in much the same way you work with feature layers and stand-alone tables.

Open a feature sublayer's attribute table to see the properties of entities that can have spatial features. Open a table sublayer in the knowledge graph layer to see the properties of nonspatial entities and relationships.

Note:

You can open a maximum of 13 content items at the same time in Knowledge Studio. If you have reached this limit, you need to close a tab before you can open a map.

Create a blank map

After you create a blank map, use any of the other methods listed to add data to the map.

1. In the Investigation Contents pane, click Add Content.
2. Click Map .

A map is created in the Investigation Contents pane.

Add a knowledge graph layer from the knowledge graph view

You can add a single record, an entire entity type, or specific instances of an entity or relationship type to a map from the knowledge graph view. When you add content to a map, a knowledge graph layer representing the entire knowledge graph is created and added to the map. New maps appear in the Investigation Contents pane.

Add a single entity or relationship

A record displayed in the details pane can be added to a map.

1. On the context toolbar, click Add Record To .
2. Click the appropriate option to add a knowledge graph layer to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Add multiple entities or relationships

Multiple records of an entity or relationship type can be added to a map from the knowledge graph view.

1. Check the check boxes to select entities or relationships from the record list.
2. From the record list, click Add Selection To .
3. Click the appropriate option to add a knowledge graph to the link chart.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Add an entire entity or relationship type

All records of an entity or relationship type can be added to a map.

1. Hover over an entity or relationship type in the contents pane and click Add Selection To .
2. Click the appropriate option to add a knowledge graph layer to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Note:

If you add an entire entity or relationship type to a map from the knowledge graph view, you cannot remove individual entities or relationships of that type.

Add an entire knowledge graph

All instances of an entity or relationship type can be added to a map.

1. In the contents pane, click Add Selection To next to the knowledge graph you want to add to the map.
2. Click the appropriate option to add a knowledge graph layer to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Note:

You cannot remove entities and relationships when you add an entire knowledge graph to a map from the knowledge graph view.

Add a knowledge graph layer from global search

Entities and relationships returned in global search results can be added to new or existing maps.

1. Select a record by checking its check box.
2. Click Add Selection To at the top of the search results pane.
3. Click the appropriate option to add the selected records to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Add a knowledge graph layer from a link chart

After you create a link chart from an investigation's knowledge graph, you can add records from the link chart to a map.

1. Select the entities and relationships in the link chart to add to the map.
   • Press the Ctrl key while clicking the entities and relationships.
   • Click Select All to select all entities and relationships.
   • Select records in the entity or relationship type sublayer record table.
   • Press the Ctrl key while clicking selected entities and relationships on the canvas to deselect them.
   • Click anywhere on the canvas to deselect all entities and relationships.
2. On the context toolbar, click Add Selection To .
3. Click the appropriate option to add a knowledge graph layer to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Add a knowledge graph layer from a map

After creating a map from an investigation's knowledge graph, you can add entities and relationships from the existing map to another map.

1. Select the entities and relationships in the map that you want to add to the new map.
   • Press the Ctrl key while clicking the entities and relationships.
   • Select records in the entity or relationship type sublayer record table.
   • Press the Ctrl key while clicking selected entities and relationships on the canvas to deselect them.
   • Click anywhere on the canvas to deselect all entities and relationships.
2. On the context toolbar, click Add Selection To .
3. Click the appropriate option to add a knowledge graph layer to the map.
   • Under Add to new, click Map to create a map in the project.
   • Under Add to existing, click the name of an existing map.

Turn the visibility of knowledge graph layers and sublayers on or off

You can show or hide the knowledge graph layer and entity type and relationship type sublayers on a map.

1. Click Options next to the layer in the Map Contents pane.
2. Click Toggle visibility to show or hide the knowledge graph layer and its sublayers.

Rename a knowledge graph layer or sublayers

A knowledge graph layer and its sublayers can be renamed in the map. Changing the name only changes the display name of the layer in the Map Contents pane of the current map. It does not change the layer's name across other maps in the project, or the name of the entity type or relationship type the layer represents.

1. Click Options next to the layer in the Map Contents pane.
2. Click Rename .

   The rename dialog box appears.

3. Provide the new layer name and click OK.

Remove knowledge graph records from a map

Entities and relationships can be removed from a map. Removed records remain in other maps, link charts, and data cards in the project.

Note:

You cannot remove entities or relationships from a map if the entire knowledge graph was directly added to the map from the knowledge graph view. If an entire entity type or relationship type is added to a map from a knowledge graph view, individual records of this type cannot be removed from the map.

1. Select the entities and relationships you want to remove from the map.
   • Press the Ctrl key while clicking the entities and relationships.
   • Select records in the entity or relationship type sublayer record table.
   • Press the Ctrl key while clicking selected entities and relationships on the canvas to deselect them.
   • Click anywhere on the canvas to deselect all entities and relationships.
2. On the context toolbar, click Remove .

View the legend

Each entity type and relationship type in the map has default symbology applied. Use the legend to see the symbology for each sublayer.

On the context toolbar, click Toggle Legend .

Change the basemap

By default, all maps use your organization basemap. You can change the basemap for the open map using the context toolbar.

1. On the context toolbar, click Change Basemap .
2. Choose the basemap to use.
