  2. Click the Review tab.
  3. In the QC group, click Check Events.
    The Check Events tool

    The Check Events on Route widget appears.

  4. Click the Network (LRM) drop-down arrow and choose the LRS Network that will serve as a source for selecting the location of the quality control check.

    This can be any LRS Network published as a layer in the Event Editor.

  5. If your network is configured to have a route name, the Route Name text box appears, otherwise the Route ID text box will appear. Type a route name or a route ID. You can also use the drop-down list to do the following:

    This can be any LRS Network published as a layer in Event Editor.

    • Select the Choose Routes option and use the Select a Route on the Map tool Select a Route on the Map to pick the route that will be used to check events.
    • Select the Selected Routes option to pick all the routes that are selected using the route selection method.
    • Select the Highlighted Routes option to pick only the routes that are highlighted from the route selection set.

    The selected routes are now highlighted on the map.

  6. Type a From Measure value of the intended start location of the quality control check along the route in the From Measure text box, or use the Select From Measure on the Map tool Select From Measure on the Map to select the start location from the map.

    A green plus appears at the selected location on the map.

  7. The Select From Measure on the Map tool is disabled if you choose either the Selected Routes or the Highlighted Routes option. In those cases, the From Measure defaults to the Start Measure of the route.
  8. Enter a To Measure value of the intended end location of the quality control check along the route in the To Measure text box, or use the Select To Measure on the Map tool Select To Measure on the Map to select the end location from the map.

    If you do not enter the From and To Measure values, the tool runs with the Start and End Measure values of the route.

    A red cross symbol appears at the selected location on the map.

  9. The Select To Measure on the Map tool is disabled if you choose either the Selected Routes or the Highlighted Routes option. In those cases, the To Measure defaults to the End Measure of the route.
  10. Choose an option for validating events.
    • Check all event layers in the map.
    • Choose all the events present in a particular attribute set. For more information on how to create an attribute set containing multiple events, see Configuring attribute sets.
    • Choose a specific event layer using the drop-down arrow.
  11. Select checks.
    • Detect Gaps
    • Detect Overlaps
    • Detect Invalid Measures
  12. Click Run Checks.
