Configuring event replacement

While performing roadway maintenance, sometimes a road section is replaced by a new section.

During the roadway replacement, the events that were part of the replaced section can be left as is, retired, or retired and replaced using the Event Replacement widget. The measures for the route do not change. For example, the following diagram illustrates a roadway section before replacement

Roadway events before replacement are shown.

A road with a From measure of 0 and a To measure of 10 exists. Various line and point events are present on the road as shown above.

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

The workflow for event replacement in ArcGIS Event Editor involves the following two stages:

  • Configuring event replacement using the Configure Event Replacement widget
  • Replacing events using the Event Replacement widget

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. Open ArcGIS Event Editor and, if prompted, sign in to Portal for ArcGIS or ArcGIS Online.
  2. Click the Edit tab.
  3. In the Edit Events group, click the Configure Event Replacement button Configure Event Replacement.

    The Configure Event Replacement widget appears.

    Note:

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

    Opening the Configure Event Replacement widget

    Tip:

    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 selected 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 will be retired when events in the category are replaced using the Event Replacement widget.

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

    Only line events Line Events can be retired and replaced.

    Note:

    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.

    Note:

    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.
    Note:

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

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

    The Default button defaults to the event replacement configuration provided in the ArcGIS 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.
