You can merge two or more line events using the Merge Events tool available in the ArcGIS Event Editor or through the attribute table.
Merging events with the Merge Events tool
Upon successful execution, the Merge Events tool merges multiple adjoining events into an existing target event. All the input events, except the target event, retire. The merged event acquires the lowest value from the From Measure field and highest value of the To Measure field from the input events by default. If a gap exists between the input events, the gap is bridged in the merged event. You can edit the attributes of the merged layer prior to committing the merge.
In the following image, if two events are merging and the From Measure of the starting event (EventId A) and the To Measure of the ending event (EventId B) have referent offset values, the resulting merged event (event A) will retain the referent offset values as its From Measure and To Measure.
Use the following steps to merge events in the Event Editor.
- Ouvrez ArcGIS Event Editor et, si vous y êtes invité, connectez-vous à Portal for ArcGIS ou ArcGIS Online.
- Cliquez sur l’onglet Mise à jour.

The event's attribute table opens at the bottom with the selected events highlighted in green.
The participating events's EventID is listed in the Target Event drop-down list.
- Optionally change the From Measure, To Measure, Start Date, and End Date values.
The start date defaults to today's date. All the records highlighted in green will be merged to the target event.
- Optionally edit the characteristic attributes in the table.
The attributes are from the Target Event by default.
Remarque :
