Vector-based maps are an advanced capability of digital moving-map systems that are easily
customised and can be powerful aids to aircrew information processing and decision-making. However, they may place excessive demands on an aircrew's information processing
requirements, cause an increase in workload, and degrade situational awareness if the user
interface is not designed properly. There is little information available about the human
factors and situational awareness issues relevant to vector-based maps. In this paper, we
summarise relevant research on human factors and situational awareness aspects of using
vector-based maps, identify key issues, and recommend directions for future research.
