Input and settings view

Click to pin the Date & Time, Event timeline and Sources to the Legends view.

Click to minimize the Input and settings view on the map. When it is minimized an icon is displayed on the top-left of the map. The icon is either red or green depending on whether or not you have loaded the case data on the screen by clicking Refresh.

This allows you to select the time period of interest. Using this information it searches the data you uploaded to the case for phone numbers that were used during this time period and displays them in Sources. Alternatively, if you are only interested in viewing the data during events you can use Event timeline.

Start date

This setting is mandatory. This setting is automatically completed with the date and time of the earliest data from all the CDRs and geo-location files that you uploaded for the case. If you want to change the start date and time 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. This date along with the End date are used to retrieve phone numbers used during the specified time interval from the CDRs that you have uploaded.

End date

This setting is mandatory. This setting is automatically populated with the date and time of the latest data from all the CDRs and geo-location files that you uploaded for the case. If you want to change the end date and time 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. This date along with the Start date are used to retrieve phone numbers used during the specified time interval from the CDRs that you have uploaded.

Save time frame to event timeline

Select then click Refresh to save the current date/time range as an event on the Event timeline screen. The maximum time range you can set is 48 hours.

This provides an alternative to using Date & Time and instead allows you to select the event timelines of interest. Using this information it searches the data you uploaded to the case for phone numbers that were used during this time period and displays them in Sources. Once you select the required sources and click Refresh then only the data during the event timelines you selected is displayed.

This allows you to select the sources you are interested in. It displays phone numbers from the CDR data and vehicle license plate numbers if the case has geo-location files which you either manually uploaded to a license plate or that were automatically uploaded by live location monitoring to a license plate.

NOTE: This information is automatically completed from the case information.

Select which of the phone numbers you want to use in the analysis. The analysis locates the cell towers used by the selected phone numbers in addition to investigating and displaying other call properties such as the time of the call, the type of call and the phone number the call was with. By default all the phone numbers are selected. The selected phone numbers are used to select the call records and to find any sectors which were involved for the selected calls during the specified date range.

If your case has geo-location files associated with a license plate then select the license plate to include the geo-location files in the geo-location analysis and the Geo-loc data tab.

Color selector

Click the phone icon alongside the source number to select a different color.

Select a color only if you want to change the color used to represent the currently selected phone from that of the default color for the selected operator. This changes the color of the sectors and event markers used to represent this phone on the ESPA analysis center screen and the Smart track triggered alerts screen. This setting is useful if you have multiple phones from the same operator and you want to display each with a different color.

This setting is coupled with the Display color setting on the People and devices screen.

Source number

If not all data sources are selected or if a timezone adjustment has been set an icon is displayed alongside the source number.
