Modifying shared line events that are contiguous (Production Mapping)

注意:

At version 10.2.1, linear referencing functionality is deprecated. Tools associated with linear referencing in Production Mapping can still be found in the Customize dialog box, but the Production Linear Referencing toolbar is no longer available. At the next major release of Production Mapping, this functionality will not be available.

It is recommended that you use Esri Roads and Highways to maintain your linear referencing information.

Some linear events, such as pavement conditions and speed limits, are used to describe route attributes that exist continuously along the route. While every location along the route has a pavement condition, the condition may not be the same along the entire length of the route. The Modify Shared Line Event tool allows you to adjust the value in the to- or from-measure field to ensure two events are contiguous, without overlaps or gaps. The tool can also be used to extend one event along a route and automatically adjust an adjacent event to maintain the coincidence of their endpoints.

When the events are already contiguous, the measure where one event ends is the same measure where another starts.

When you choose the location where the two events meet, the shared point is displayed in the map and can be moved to adjust the lengths of both events. In the illustration below, the shared point is selected between the two events and can be used to adjust the values in the to-measure field of one and the from-measure field of the other.

The map tip displays the current location of the shared point as it is moved along the route. When the new location is selected, the values are updated for the poor pavement event's to-measure and the good pavement event's from-measure. The updated events are symbolized in the map.

Example of coincident events with the shared point selected

If an entire event is selected, you have the option of choosing whether the event is modified using its starting point or endpoint. After you choose a point to use and select a new location, the to- and from-value of the feature are modified, and the events are redrawn on the map.

手順:

1. Start ArcMap.
2. Load event layers in the map.
   注意:

   When working with joins and event layers, make sure you add the event layer before you perform the join to ensure that edits to the event layer are performed correctly. If you join the event table before adding it as an event layer, you cannot update the attributes of the event while editing, and some of the event editing may not work.

3. On the main menu, click Customize → Toolbars → Production Editing.
4. Add the necessary tools by doing the following:
   1. Click Customize → Customize Mode on the main menu.

      The Customize dialog box appears.

   2. Click the Commands tab.
   3. In the Categories list, click Production Editing.
   4. Click and drag the Modify Shared Line Event button to a toolbar.
   5. Click and drag the Select Route Events button to a toolbar.
   6. [閉じる] をクリックします。
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.

   ヒント:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button on the Manage Features window.

6. Click the Modify Shared Line Event button .
7. Click the Select Route Events tool .
8. Select two events in the map by clicking and dragging a box around them.

   If an entire event has not been selected, the common point between the events is displayed as a red box.

9. Click and drag the box to where you want the first event to end and the second one to begin, then click the line.

   The value of the to-measure field is updated for the first event, and the value of the from-measure field is updated for the second event.

Both events are redrawn in the map to reflect the new values.
