Removing duplicate centerline geometry

The ArcGIS Roads and Highways minimum schema models route concurrency by having routes share the same centerline associations in the centerline sequence table. Roads and Highways supports translating measures between networks the same way. The Remove Centerline Geometry Duplication tool takes care of ensuring there is only one common centerline in cases where centerline geometry overlaps. This may result in centerline changes, such as centerline splitting or even deletion of duplicated centerline features. It may also result in updated centerline sequence records to have routes share centerlines.

Overlapping centerlines can result when:

• Loading a network with routes and the network being loaded has concurrent routes
• Loading another network in addition to an already-loaded network
• Ad-hoc user centerline editing can result in centerlines overlapping

Hinweis:

While you can run the Remove Centerline Geometry Duplication tool at any time once you've successfully created an LRS Network and loaded data, you should consider only running the tool after you've finished creating all LRS Networks and loading all data in your LRS.

If additional columns are modeled on the centerlines, some of these attributes could be lost on centerlines deleted during the Remove Centerline Geometry Duplication process.

1. Start ArcMap.
2. In the Catalog window, right-click your LRS and click Remove Centerline Geometry Duplication.

   

   A progress dialog box appears and shows the steps and progress of duplicate centerline removal.

   Hinweis:

   This operation could take a significant amount of time to execute due to the work being done to the data. Running the Remove Centerline Geometry Duplication tool could result in hundreds of thousands of database operations, depending on the number of centerlines. If your LRS is inside a multiuser geodatabase, consider unregistering as versioned the centerline feature class, centerline sequence table, and the network feature class before running this tool. Once the tool is finished, reregister these elements as versioned. For more information, see A quick tour of registering and unregistering data as versioned.
