ABSTRACT
Visualization is an emerging science that draws from a rich and diverse research literature including computer graphics, computational geometry and theories of human perception from cognitive science and psychology. From a GeoComputation (GC) perspective, visualization is an advanced form of display technology offering the potential for improving the efficiency and effectiveness of data communication between the machine and the user. From the perspective of human-computer interaction, visualization can be viewed as one member of a larger family of methods, where interaction is restricted to the visual domain only and specifically by forming images, scenes or virtual realities to graphically portray data. In sighted humans, vision is the dominant sense, making it the strongest candidate on which to base interaction with the computer (McCormick et al., 1987).
