Creating elevated segments to complete a network segment

In defense data, it is common to have instances in which a road feature ends when there is a bridge that overlays it. When this occurs, there may be a road feature that should be continuous but is instead divided by a bridge.

The Create Elevated Segments tool creates the underlying feature for the bridge based on the Transportation Use Category (TUC) or Transportation System Type (TRS) attribute value for the bridge. Using this tool, you can create a road, railroad, or aqueduct feature. For example, if you have a bridge feature that is surrounded by a road, you can use the tool to create a road feature beneath the bridge that is part of the road network.

步骤:

1. Start ArcMap.
   提示:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. Load the following layers in the table of contents, as appropriate:
   • BridgeL
   • AquedctL
   • RailrdL
   • RoadL
3. On the main menu, click Customize > Toolbars > Production Editing.
4. On the main menu, click Customize > Toolbars > Defense Mapping.
5. Click the Production Start Editing button on the Production Editing toolbar.
   注意:

   The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.

   提示:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Link Feature Manager To Attributes Window button on the Manage Features window.

6. Select one or more bridge features in the map.
7. Click the Create tab on the Manage Features window.
8. Right-click the BridgeL feature class on the Create tab tree view and click Keep Selected.

   Only the bridge features are selected.

9. Click the Create Elevated Segments button on the Defense Mapping toolbar.

Based on the value in the TUC field, new features are created. These can be road, railroad, or aqueduct features.
