Analyzing which persons are in the same location at the same time

This topic details how to view which persons were within a specified distance of each other within a specified time interval. You can specify this distance and time interval using the Advanced options dialog box. This analysis uses both geo-location and CDR data.

2. Click Common location-time to expand the list. Note, a before the analysis name indicates that the analysis has been run. If is displayed, you must click it to run the analysis first.

3. Click beside the common location, which is identified by Location<n>, to display the details of the phone numbers or license plates. This displays all the phone numbers or license plates that had geo-location events or used sectors within this common location and within the displayed time interval.

   

   If you want to investigate these locations, or the geo-location events or calls from these locations further continue with the following steps. Step 4 details how to zoom to the location on the map, and step 5 onwards details how to investigate the geo-location events or calls further using the Geo-loc data and CDR data tabs.

4. On the Geo-loc analyses tab right-click the location you want to investigate further, then select Zoom to this item. This will zoom to the latitude and longitude where the most geo-location events occurred in the defined location. If there is not one latitude and longitude point with more geo-location events than others then it zooms to the geo-location event with the first latitude and longitude in the defined location. All sectors that were included in the location's result are displayed with a bold black outline.
