Spatiotemporal Data Visualization using Morphing Approach

The research area of spatiotemporal visualization has received much attention over the past decade due to its challenging aspects and high benefits. In this paper we present the visualization of spatiotemporal data in the form of earth terrain movements. An additional temporal dimension t is added to the terrain spatial dimensions of x, y and z thus creating a spatiotemporal visualization system. Many existing visualization system uses animation to visualize spatiotemporal data. This paper however takes a closer look into a different approach of terrain movement visualization which is morphing. By using morphing technique, the structures of terrain that changes over time can be viewed in detail. A simple visualization tool was built to demonstrate this idea and we believe that with gradual improvements, it holds a very promising prospect to be commercialized.
