The aim of this paper is to discuss the role of maps in the cognition of geographic space. The research topics were divided into (1) maps as a model of spatial cognition, and (2) maps as a source of spatial knowledge. As for the first topic, maps have become a conceptual model of the spatial cognition and enabled us to elaborate the model of cognitive processing of geospatial information, since Tolman (1948) devised the term of “cognitive map”. As a result, methods for measuring distortions in cognitive maps has been developed and applied by geographers. On the other hand, the role of maps as a source of spatial knowledge will become important as geographic information technologies spread among people. Specifically, advanced techniques for communicating geographic information through 3D view, animation, sound, and VR enabled by GIS lead to reconsideration of the dichotomy between direct and indirect sources of information. Hence, recent trend of digitization of geospatial information can change the role of maps in the cognition of geographic space.
