An electronic map may be output based on map data including information related to a current configuration of each of a plurality of map objects and historical attributes of at least a portion of the plurality of map objects. The historical attribute associated with a map object may include information related to a historical configuration of the respective map object in the past. A time selection input may be received at a user interface. The map data may be processed to identify a map object having a current configuration different from a historical configuration at a time in the past which is determined based on the time selection input. An optical output device may be controlled to output a graphical representation of the identified map object that is dependent on both the current configuration and the historical configuration of the identified map object.
