Chapter 6 Cognitive Processes and Cartographic Maps [chapter]

Robert Lloyd
1993 Advances in Psychology  
This paper represents the result of enriching cartographic maps with features used by pedestrians for navigation in urban areas.  ...  Users of cartographic maps must accomplish all of the way-finding, positioning and orientation tasks by themselves through connecting the elements of the environment and the map.  ...  This knowledge is used to move in routes and paths based on a sequence of landmarks, features, junctions, and nodes. Route knowledge is based on egocentric view [1] .  ...
