Explore Network

The source features of a network dataset can be added to the map display and the network elements and attributes of a network dataset layer can be examined using the Explore Network and Add Network Sources tools on the Data tab's Explore section.

The tools are available when you have a network dataset added to the map display and also when a network analysis layer is created and added to the Contents pane. When you a select network dataset or a network analysis layer in the Contents pane, the Explore Network and Add Network Sources tools become available on the ribbon.

Explore Network and Add Network Sources tools appear on the ribbon when a network dataset is added in the Contents pane.

Note:
The Explore Network and Add Network Sources tools are only available when the network data source of the selected network dataset layer or analysis layer is a file geodatabase, a mobile geodatabase, or an enterprise geodatabase. The tool is not available with a service- or shapefile-based network data source.

Explore network

You can inspect network elements and attributes of a network dataset referenced by a network dataset layer or network analysis layer in the map display using the Explore Network tool. The tool can help identify the following:

  • What network elements are associated with a source street feature
  • What other network elements are adjacent to it
  • The cost to traverse it
  • Whether its attributes are configured properly to return the expected values
  • Whether it is restricted by the active travel mode

Explore network window

When you activate the Explore Network tool and select an element or multiple elements in a network dataset, the Explore Network window appears. This is a dockable window and is divided into two parts:

  • Network Elements—The upper part of the window displays the network elements identified in the map by the Explore Network tool. These are grouped by element type—Edges, Junctions, and Turns. Each element in the elements list is represented by the element ID (EID) and the object ID (OID) of its associated source feature. If the network dataset's vertical connectivity policy is elevation fields, the element item header also includes logical elevation values for its endpoints of the associated source feature of each network element. For example, in the highlighted edge below, Elev (0,1) indicates the logical elevation at its from and to ends, respectively.
    Network Elements

    If an edge source uses any vertex group connectivity policy, some edge elements for that source will only cover part of the geometry of their associated source feature geometry. For example, EID:39703, OID: 19045 [0.13 - 0.85] indicates that this edge covers only a portion of its source feature geometry in the range from 13 percent to 85 percent along the edge. The other two edge elements, EID:39924, OID: 19045 [0 - 0.13] and EID:39699, OID: 19045 [0.85 - 1], cover the remaining portion of the source Streets feature with OID: 19045. The example below highlights the source feature that is made of these three edge elements.

  • Element details—The bottom part of the window is composed of the network element header summary, Travel Attributes subtab, and Connectivity subtab. Together these describe different aspects of the primary selected element.
    • Network element header summary—Displays a summary of the currently selected network element, for example, Edge (EID:4881) - Streets (OID: 17710) - Elev: (0,1).
    • Travel Attributes—This tab is in the lower part of the window and displays the travel attributes associated with the network dataset.
      • Values—On this tab, for edges, two sets of attributes (one for each direction) are displayed: the name of the attribute, the value along the digitized direction for an edge, and the value against the digitized direction for an edge. For junction and turn elements, the values are reported in a single column because junctions don't have direction and turns are defined in only one direction.
        Travel Attributes tab
      • Settings—On this tab, you can specify the source of the travel mode and time query options.

        In the Travel Mode section, you can choose the source of your travel mode to come from the network dataset or from a network analysis layer.

        • From this network dataset—When this option is selected, you can choose the available travel modes defined on the current network dataset, from the Name drop-down list.
          Change the travel mode settings on the Settings subtab.
        • From a network analysis layer—When this option is selected as the source, you can choose the network analysis layer from the Layer drop-down list that contains all the network analysis layers in the map that share the same local network data source. The Name option is disabled, and displays the name of the travel mode from the selected network analysis layer.
          Network analysis layer as the travel mode source
        • None—Not using a travel mode.

        In the Time Query Options section, you can select options from the Time Usage drop-down list to apply query settings to further configure the active network element query used to update the displayed travel attribute values.

        Time query options

        When the travel mode source is this network dataset, the Time Usage is editable unless the travel mode source is a network analysis layer and Use time settings from network analysis layer is checked. Depending on the chosen time usage, additional time query options can also be configured. You can use the time settings of the source network analysis layer to be applied to the query as well. If the source network analysis layer properties relevant to the query are edited in its ribbon or property page, the travel attributes values will automatically be re-queried. However, there can be some cases in which a change in properties of the source network analysis layer travel mode or time settings is not recognized. If this happens, you can explicitly refresh the query settings from the source network analysis layer and force a re-query of the travel attributes with those settings using the Re-query Travel Attribute Values button Refresh.

        On the Values tab, when you click the Filter Travel Attributes in Travel Mode button Filter, only the attributes used by the active travel mode and time query, if specified, will be displayed.

    • Connectivity—This tab, also in the lower part of the window, displays the connected and adjacent elements.

Identify network elements in the map display

In the image below, the left side shows the elements identified from a network dataset using the Explore Network tool. The Explore Network window, on the right, displays the attributes associated with the identified elements. The image shows that a total of 7 network elements are identified, which are displayed individually with the number of elements in each category: Streets (5), Junctions (1), and Turns (1), respectively. See the table below to learn more about the information that is updated in the Explore Network window based on the selection you make in your map display.
