ABSTRACT
This chapter itemizes the characteristics of geo-photos in relation to the human acquisition of spatial knowledge by reviewing the theoretical and experimental knowledge in literature about the human spatial cognition and reading of geospatial images (abbr. geo-images). A literature-based framework for evaluating the support of geo-images for spatial knowledge is used in assessing the effects of vantage point, number of visible vertical features, and visual realism for supporting landmark, route, and configurational spatial knowledge types. Particularly, the significance of high visual realism of photographs is addressed.
