Modifying shared line events that are not 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.

An overlap or gap occurs between two line events when the measure values of the selected ends of two events are not the same.

When this occurs, you are asked if you want to make the two event endpoints coincident. If you do not choose to make the events coincident, the tool cannot be used.

With this example, the poor pavement event is separated from the good pavement event by a small gap. Selecting the two events displays a message that notifies you that the selected to- and from-measure points are not coincident and asks if you want to make them coincident. If you choose to make the two events coincident, you can click the location along the route where you want two events to meet.

After a point is selected, the value is updated in the to-measure field for the poor pavement event, and the from-measure value is updated for the second event. The events are also redrawn to reflect the new measure values in 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.

   A message appears asking whether or not you want to make the events coincident.

9. Click Yes.

   The cursor changes to a turquoise circle, and a MapTip displays its current measure value along the route.

10. Drag the cursor to the new location 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.
