Event timeline screen

This topic provides an overview of the Event timeline screen and all the settings and buttons on it.

The Event timeline screen allows you to manage all the events associated with the case. You can create your event with or without an associated a location.

Events are used to determine if the device was at a location during the event time. The Event timeline screen allows you to add multiple events to the one location. Currently only the geo-fence analysis supports analyzing multiple events at the one location.

Events can also be created automatically when you upload a geofence or tower dump file. If there is not already an event for the same location and time frame then a new event is created and named "<Location name>,Event<n>", however if there is already an event for the same location and time frame then the new file data is added to the existing event and the event start and end times adjusted if required.

Single events associated with a location can also be added to a case from the Locations of interest screen (Case management). These events are also automatically added to the Event timeline, however deleting them from the timeline does not remove them from the Locations of interest screen (Case management) so that you can still use the event in your other analyses. You can also import a location file from the Locations of interest screen containing multiple locations and if the file also includes event times then an event is also automatically created on the Event timeline screen.

The Event timeline screen also allows you to add events without associating them with a location. Events with and without locations are both included in the Person whereabouts analysis.

You can also filter what data is displayed on the ESPA analysis center screen by the events using Event timeline on the Input and settings view.

NOTE: When performing a target development analysis, after making any changes to the event timeline you must reconsolidate the analysis before viewing the results on the ESPA analysis center's Target development view. You can reconsolidate your analysis by clicking Reconsolidate default analysis on the Target development management tab of the Manage files screen.

This lists all the events that have been added to the case. Click on an event to view or edit its details. If you edit the details you must click the relevant Save button to save any changes otherwise any changes you make are lost if you move to another screen. To delete existing events click , then from the dialog box, select the check-box next to the event you want to delete then click Delete selected.

Click to add an additional event to the case.

Click if you want to delete events. A dialog box opens allowing you to select which events you want to delete.

The Event details tab allows you to manage the event's name, date and time.

Enter a name for your event which is meaningful to you.

You can also edit existing names, such as those automatically created by OSS-ESPA. When you upload geofence or tower dump files OSS-ESPA automatically creates an event based on the times detailed in the file. Events created automatically, for example when you upload a geofence file or from the Locations of interest screen (Case management), are named "<Location name>,Event<n>".

Enter the event start date and time. For example if it is a crime scene you can enter the date and time the crime started. You can use the date and time pickers to enter the details, or you can enter them manually. If you enter them manually note that the date format used is month/day/year. The date and time are required for performing target development analysis of multiple events at the same location.
