Adding a bridge to a road feature

Dieses Thema gilt nur für ArcEditor und ArcInfo.

During the feature collection process, you might need to create bridges on roads to represent overpasses or other bridge structures. The Make Bridge tool allows you to create a bridge directly over a single road feature, then transfers the attributes of the road feature to the bridge. The attributes that are transferred are the Existence Category (EXS), Name (NAM), and Minimum Traveled Way Width (WD1). The Length/Diameter (LEN_, LGN, LEN) attribute is populated based on the length of the feature extracted.

The road feature will have the following fields populated:

• Location Category (LOC)
• Road Surface Type (RST)
• Weather Type Category (WTC)

You can choose which feature class to use as the target layer for bridges on the Defense Mapping Properties dialog box on the Feature Classes tab. Any feature class loaded in the map can be selected, but it is recommended that BridgeL be used.

Schritte:

1. Start ArcMap.
   Tipp:

   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. If necessary, load data in the map.
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.
   Hinweis:

   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.

   Tipp:

   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 a road feature.
7. Click the Make Bridge button on the Defense Mapping toolbar.

A bridge feature appears, along with the road feature, on the Update tab tree view on the Manage Features window.
