"Spatial navigators can construct maps in their heads as they experience a place, and also tend to be good at using maps as navigational aids." Walker opines "for spatial navigators, the answer to the question where? is a position in mapped space. For narrative navigators, the answer to where? is a story about how to get there." He believes that spatial navigation is an important tool for planners because it is "only with a spatial understanding of your city can you be attentive to certain of its possibilities and needs. Ideally, we'd get good training as children on how to develop both capabilities."
