Summary

Dynamic models require dynamic and flexible visualization

• 2d and 3d animation essential
• scriptable interface provides ability to customize
• multiple surfaces, multiple datatypes provide more freedom to visualize without adding too much complexity

Integration with GIS encourages data development

• easier to reproduce results, easier to verify or recompute suspect data
• encourages experimental use of non-obvious data, increasing probability of discovery
• exploit assumptions inherent in GIS data types to optimize visualization algorithms
