Configuring event replacement

Location Referencing ライセンスで利用可能です。

While performing pipeline maintenance, sometimes a section of a pipe is taken out of the ground and is replaced by a new pipe. This process is known as pipe replacement.

During the pipe replacement, the events that were part of the replaced pipe can be left as is, retired, or retired and replaced using the Event Replacement widget. The measures for the route do not change.

Event replacement scenario

The configuration of event replacement requires categorizing the events in the map service into three categories: As Is, Retire, and Retire and Replace using the Configure Event Replacement widget.

Before event replacement

The following diagram illustrates a pipeline section before replacement.

Pipe before replacement
Pipeline events before replacement are shown.

Before replacement, the pipe section has eight events, three point events (events 1-3) and five linear events (events 4-8).

A pipe with measures from 0 to 10 exists. Various line and point events are present in the pipe as shown above.

During inspection, it was determined that a section of the pipe between the measures 0 and 5 needs to be replaced on 12/31/2017, as shown below.

Categorizing events

The configuration of event replacement requires categorizing the events in the map service into three categories: As Is, Retire, and Retire and Replace.

To configure event replacement, complete the following steps:

  1. ArcGIS Event Editor を開き、プロンプトが表示されたら Portal for ArcGISArcGIS Online にサイン インします。
  2. Click the Edit tab.
  3. In the Edit Events group, click the Configure Event Replacement button イベント置換の構成.

    The Configure Event Replacement widget appears.

    ヒント:

    All the line events Line Events and point events Point Events available in the map service are listed in the Available Event Layers list.

    ヒント:

    If a default configuration has been created, click Default to load it. Click Reset to return to the last saved configuration in the map service.

  4. Click Shift or Ctrl and click and drag multiple line events from the Available Event Layers list to the Retire Events list.

    You can also choose event categories and use the arrow keys to move chosen line events into the lists from left to right or up and down between the Retire Events and Retire and Replace Events lists.

    Events placed in the Retire Events list are retired when events in the category are replaced using the Event Replacement widget.

    注意:

    Event layers left in the Available Event Layers list are left as is. If no events are configured to retire or to retire and replace, you'll be unable to save using the Event Replacement widget.

  6. Optionally, click the arrow for any event layer in the Retire and Replace Events list to expand it.

    An expanded list of fields in the event layer appears.

    You can use these check boxes to show or hide the fields when performing the event replacement operation.

    注意:

    Some attribute fields are required fields, which is denoted by the asterisk (*) symbol. A required field is a nonnullable field with no default value. Visibility can't be changed for required fields.

  7. Click Save to save the event replacement configuration.
  8. Click Export to export the configuration to an LRER file. Give the configuration file a name such as eventplacement1.lrer.
    注意:

    The event replacement configuration is saved in the local browser’s download folder.

  9. Copy the exported file to the Event Editor folder.
  10. Open the configuration file (config.json) in a text editor such as Microsoft Notepad.
  11. Type the LRER file name with the file extension in the eventReplacement section:

    注意:

    The Default button defaults to the event replacement configuration provided in the Event Editor configuration file.

    The Reset button restores the last saved event replacement configuration for that browser.

    You can edit the default event replacement configuration and use it in your browser.
