Deploying redline routes

The redline is a markup feature in the geodatabase that stores information about the proposed changes in the linear referencing system (LRS). Roadway characteristic editors can propose changes to the LRS through the Redline widget using redline routes. LRS editors can then apply the redline as an official change to the LRS using Roads and Highways for Desktop. The Redline Routes widget can be used to create, edit, and attach files to the redline routes. You can preconfigure redline activity types such as create route, extend route, realign route, realign concurrent route, calibrate route, retire route, reassign route, and so on.

For more information on redline routes, see:

• ALRS data model
• Using the Choose Redline tool

To enable web redlining of routes using the Roadway Characteristics Editor (RCE), you should author a web map using ArcMap and include a redline feature class. You can achieve this in one of the following ways:

• Include the redline layer in the same map service along with your routes and event layers.
• Create a separate map service for the redline.

The advantage of publishing a separate map service for the reline layer is that the feature access will only be exposed for the redline layer, not for other layers such as network and event layers. You can make the decision based on your security practices.

For detailed instructions on authoring a web map and configuring RCE, see:

• Configuring the Roadway Characteristics Editor web application
• Using a web map
• Roadway Characteristics Editor deployment guide

Note:

In the redline feature class, the attribute fields for which the Roadway Characteristics Editor application user may not be able to provide data must be made nullable. Doing so will make the data content for those fields optional.

Items to confirm before you start

Before you deploy redline routes capability in RCE, check that the following are true:

• Feature access and linear referencing capabilities are enabled
• The redline feature class has the m- and z-values disabled
• Symbology is defined for the Activity Type field

Enabling feature access and linear referencing capabilities

• If you're including the redline layer in the same map service as your network and event layers, make sure to enable the Feature Access and Linear Referencing capabilities when publishing the map service using ArcGIS for Server.

  

• If you're publishing the redline layer separately, make sure to enable only the Feature Access capability when publishing the map service using ArcGIS for Server.

Note:

The Roadway Characteristics Editor web application supports webmap, which has only one linear referencing capable map service.

Disabling m- and z-values for the redline feature class

The redline feature class should have the capability to store disabled m- and z-values. To validate this, perform the following steps:

1. Start ArcCatalog.
2. Navigate to the redline feature class in your database.
3. Right-click the redline feature class and click Properties.
4. Click the General tab.
5. Confirm that both check boxes in the Geometry Properties area are unchecked.

   

Defining symbology for the Activity Type field

The symbology for the redline feature class's activity types should be set up.

1. Open the .mxd file that contains the redline layer.
2. Right-click the redline layer in the table of contents and click Properties.
3. Click the Symbology tab.

   

4. Choose Activity Type in the Value Field list.
5. Click Add All Values.
6. Choose line symbology for various redline activity types.
7. Click OK.

Deploying redline routes

Use the following steps to deploy redline routes for RCE.

• Configuring redline activity types
• Enabling redline attachments

Configuring redline activity types

You can configure redline activities by using the following steps:

1. Start ArcMap.
2. Display the Catalog window, and browse to the redline feature class in your database.
3. Right-click the redline feature class and click Properties.

   

4. Click the Subtypes tab.
Note that the domain assigned to the ACTIVITY_TYPE field is dActivityType.



5. Click Domains.
6. In the Workspace Domains dialog box, click the dActivityType domain name.

   You'll see preconfigured activity types in the form of coded domains for redlines in the Coded Values section. You can edit the activity types in this section.

   

7. Click Apply and click OK to close the Workspace Domains dialog box to save the edits.

Enabling redline attachments

You can enable redlines to contain attachments using the following steps:

1. Start ArcMap.
2. Open the Catalog window, and browse to the redline feature class in your database.
3. Right-click the redline feature class and click Attachments > Create Attachments.

   

Attachments will be enabled for redlines.
