Retrospectives

Retrospectives show what happened over a past period on a map. Each map is built from layers. A layer takes one kind of data, such as vehicle trips, incidents or person trails, from a time period and, if you like, an area. It then draws that data as shapes, bubbles, a heat map or shaded areas. You can save a retrospective and open it again later.

Typical questions a retrospective can answer:

• Where was a vehicle or person at a given time?
• Who, or which vehicles, were inside an area between two times?
• Who was driving a vehicle, and where did it go?
• Where do incidents of a certain kind happen most?
• Which areas got the most vehicle time or the most visits?
