Abstract
Along with the advances in computer sciences in recent years, visualization has been developed to embrace new functions. The electronic map in a spatial information visualization system is an electronic tool of human spatial cognition and has more advantages in supporting human spatial cognition than a printed map. Investigations on the ability of human spatial cognition are increasingly drawing attention of cartographers. In this background, map spatial cognition research is attached importance to cartographers again. Cognition-based visualization systems are intelligent systems that serve human spatial cognition efficiently. Developing adaptive multi-perspective visualization systems of spatial information as one kind of these systems is a main goal of our research. This paper discusses the necessity and the characteristics of map spatial cognition research. The cognitive issues involved in spatial information visualization and major contents of cognitive research in the design of adaptive visualization system are presented. Finally, the experimental methods of electronic map visual cognition are introduced.
