1. A method of operation executed by a control unit of a navigation system comprising: using a control unit of the navigation system for: determining a travel context to detect a maneuver location traveling through a geographic region in real time by a location unit; generating a mental model for the travel context, the mental model being represented by a digital model; determining a landmark-determination zone dynamically and in real time with the control unit based on a radius from the maneuver location within which a capturing sensor detects an object; determining a guidance landmark including at least one of a stationary landmark and a dynamic landmark based on the mental model, the landmark-determination zone, or a combination thereof for providing a navigation guidance; and transmitting the guidance landmark for presenting on a mobile electronic device.
